More Case Study Questions
We have class 10 maths case study questions in every chapter. You can download them as PDFs from the myCBSEguide App or from our free student dashboard .
As you know CBSE has reduced the syllabus this year, you should be careful while downloading these case study questions from the internet. You may get outdated or irrelevant questions there. It will not only be a waste of time but also lead to confusion.
Here, myCBSEguide is the most authentic learning app for CBSE students that is providing you up to date study material. You can download the myCBSEguide app and get access to 100+ case study questions for class 10 Maths.
How to Solve Case-Based Questions?
Questions based on a given case study are normally taken from real-life situations. These are certainly related to the concepts provided in the textbook but the plot of the question is always based on a day-to-day life problem. There will be all subjective-type questions in the case study. You should answer the case-based questions to the point.
What are Class 10 competency-based questions?
Competency-based questions are questions that are based on real-life situations. Case study questions are a type of competency-based questions. There may be multiple ways to assess the competencies. The case study is assumed to be one of the best methods to evaluate competencies. In class 10 maths, you will find 1-2 case study questions. We advise you to read the passage carefully before answering the questions.

Cbse 10th standard maths subject case study questions with solution 2021 part - ii answer keys.
(i) (a): 1 st situation can be represented as x + 7y = 650 ...(i) and 2 nd situation can be represented as x + 11y = 970 ...(ii) (ii) (b): Subtracting equations (i) from (ii), we get \(4 y=320 \Rightarrow y=80\) \(\therefore\) Proportional expense for each person is Rs 80. (iii) (c): Puttingy = 80 in equation (i), we get x + 7 x 80 = 650 \(\Rightarrow\) x = 650 - 560 = 90 \(\therefore\) Fixed expense for the party is Rs 90 (iv) (d): If there will be 15 guests, then amount that Mr Jindal has to pay = Rs (90 + 15 x 80) = Rs 1290 (v) (a): We have a 1 = 1, b 1 = 7, c 1 = -650 and \(a_{2}=1, b_{2}=11, c_{2}=-970 \) \(\therefore \frac{a_{1}}{a_{2}}=1, \frac{b_{1}}{b_{2}}=\frac{7}{11}, \frac{c_{1}}{c_{2}}=\frac{-650}{-970}=\frac{65}{97}\) \(\text { Here, } \frac{a_{1}}{a_{2}} \neq \frac{b_{1}}{b_{2}} \neq \frac{c_{1}}{c_{2}}\) Thus, system of linear equations has unique solution.
(i) (a): Situation faced by Sudhir can be represented algebraically as 2x + 3y = 850 (ii) (b): Situation faced by Suman can be represented algebraically as 3x + 2y = 900 (iii) (c) : We have 2x + 3y = 850 .........(i) and 3x + 2y = 900 .........(ii) Multiplying (i) by 3 and (ii) by 2 and subtracting, we get 5y = 750 \(\Rightarrow\) Y = 150 Thus, price of one Physics book is Rs 150. (iv) (d): From equation (i) we have, 2x + 3 x 150 = 850 \(\Rightarrow\) 2x = 850 - 450 = 400 \(\Rightarrow\) x = 200 Hence, cost of one Mathematics book = Rs 200 (v) (a): From above, we have \(a_{1} =2, b_{1}=3, c_{1}=-850 \) \(\text { and } a_{2} =3, b_{2}=2, c_{2}=-900\) \(\therefore \quad \frac{a_{1}}{a_{2}}=\frac{2}{3}, \frac{b_{1}}{b_{2}}=\frac{3}{2}, \frac{c_{1}}{c_{2}}=\frac{-850}{-900}=\frac{17}{18} \Rightarrow \frac{a_{1}}{a_{2}} \neq \frac{b_{1}}{b_{2}} \neq \frac{c_{1}}{c_{2}}\) Thus system of linear equations has unique solution.
(i) (b): Algebraic representation of situation of day-I is 2x + y = 1600. (ii) (a): Algebraic representation of situation of day- II is 4x + 2y = 3000 \(\Rightarrow\) 2x + y = 1500. (iii) (c) : At x-axis, y = 0 \(\therefore\) At y = 0, 2x + y = 1600 becomes 2x = 1600 \(\Rightarrow\) x = 800 \(\therefore\) Linear equation represented by day- I intersect the x-axis at (800, 0). (iv) (d) : At y-axis, x = 0 \(\therefore\) 2x + Y = 1500 \(\Rightarrow\) y = 1500 \(\therefore\) Linear equation represented by day-II intersect the y-axis at (0, 1500). (v) (b): We have, 2x + y = 1600 and 2x + y = 1500 Since \(\frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}} \neq \frac{c_{1}}{c_{2}} \text { i.e., } \frac{1}{1}=\frac{1}{1} \neq \frac{16}{15}\) \(\therefore\) System of equations have no solution. \(\therefore\) Lines are parallel.
(i) (b): We have \(6 x^{2}+x-2=0\) \(\Rightarrow \quad 6 x^{2}-3 x+4 x-2=0 \) \(\Rightarrow \quad(3 x+2)(2 x-1)=0 \) \(\Rightarrow \quad x=\frac{1}{2}, \frac{-2}{3}\) (ii) (c): \(2 x^{2}+x-300=0\) \(\Rightarrow \quad 2 x^{2}-24 x+25 x-300=0 \) \(\Rightarrow \quad(x-12)(2 x+25)=0 \) \(\Rightarrow \quad x=12, \frac{-25}{2}\) (iii) (d): \(x^{2}-8 x+16=0\) \(\Rightarrow(x-4)^{2}=0 \Rightarrow(x-4)(x-4)=0 \Rightarrow x=4,4\) (iv) (d): \(6 x^{2}-13 x+5=0\) \(\Rightarrow \quad 6 x^{2}-3 x-10 x+5=0 \) \(\Rightarrow \quad(2 x-1)(3 x-5)=0 \) \(\Rightarrow \quad x=\frac{1}{2}, \frac{5}{3}\) (v) (a): \(100 x^{2}-20 x+1=0\) \(\Rightarrow(10 x-1)^{2}=0 \Rightarrow x=\frac{1}{10}, \frac{1}{10}\)
Number of pairs of shoes in 1 st , 2 nd , 3 rd row, ... are 3,5,7, ... So, it forms an A.P. with first term a = 3, d = 5 - 3 = 2 (i) (d): Let n be the number of rows required. \(\therefore S_{n}=120 \) \(\Rightarrow \quad \frac{n}{2}[2(3)+(n-1) 2]=120 \) \(\Rightarrow \quad n^{2}+2 n-120=0 \Rightarrow n^{2}+12 n-10 n-120=0\) \(\Rightarrow \quad(n+12)(n-10)=0 \Rightarrow n=10\) So, 10 rows required to put 120 pairs. (ii) (b): No. of pairs in 1ih row = t 17 = 3 + 16(2) = 35 No. of pairs in 10th row = t 10 = 3 + 9(2) = 21 \(\therefore\) Required difference = 35 - 21 = 14 (iii) (c) : Here n = 15 \(\therefore\) t 15 = 3 + 14(2) = 3 + 28 = 31 (iv) (a): No. of pairs in 30 th row = t 30 = 3 +29(2) = 61 (v) (c): No. of pairs in 5 th row = t 5 = 3 + 4(2) = 11 No. of pairs in 8 th row = t 8 = 3 + 7(2) = 17 \(\therefore\) Required sum = 11 + 17 = 28
Let the numbers on the cards be a, a + d, a + Zd, ... According to question, We have (a + 5d) + (a + 13d) = -76 \(\Rightarrow\) 2a+18d = -76 \(\Rightarrow\) a + 9d= -38 ... (1) And (a + 7d) + (a + 15d) = -96 \(\Rightarrow\) 2a + 22d = -96 \(\Rightarrow\) a + 11d = -48 ...(2) From (1) and (2), we get 2d= -10 \(\Rightarrow\) d= -5 From (1), a + 9(-5) = -38 \(\Rightarrow\) a = 7 (i) (b): The difference between the numbers on any two consecutive cards = common difference of the A.P.=-5 (ii) (d): Number on first card = a = 7 (iii) (b): Number on 19th card = a + 18d = 7 + 18(-5) = -83 (iv) (a): Number on 23rd card = a + 22d = 7 + 22( -5) = -103 (v) (d): \(S_{15}=\frac{15}{2}[2(7)+14(-5)]=-420\)

Q. No. 1) Manpreet Kaur is the national record holder for women in the shot-put discipline. Her throw of 18.86m at the Asian Grand Prix in 2017 is the maximum distance for an Indian female athlete. Keeping her as a role model, Sanjitha is determined to earn gold in the Olympics one day.
![math case study examples class 10 cbse class 10 maths important questions](https://www.cbseguidanceweb.com/wp-content/uploads/2024/03/Screenshot-2024-03-09-152322.png)
Initially, her throw reached 7.56m only. Being an athlete in school, she regularly practiced both in the mornings and in the evenings and was able to improve the distance by 9cm every week.
During the special camp for 15 days, she started with 40 throws and every day kept increasing the number of throws by 12 to achieve this remarkable progress.
(i) How many throws Sanjitha practiced on 11th day of the camp?
(ii) What would be Sanjitha’s throw distance at the end of 6 weeks?
When will she be able to achieve a throw of 11.16 m?
(iii) How many throws did she do during the entire camp of 15 days?
Ans. (i) Number of throws during camp. a = 40; d = 12 𝑡 11 = 𝑎 + 10𝑑 = 40 + 10 × 12 = 160 𝑡ℎ𝑟𝑜𝑤𝑠
(ii) a = 7.56 m; d = 9cm = 0.09 m n = 6 weeks t n = a + (n-1)d = 7.56 + 6(0.09) = 7.56 + 0.54 Sanjitha’s throw distance at the end of 6 weeks = 8.1 m
a = 7.56 m; d = 9cm = 0.09 m t n =11.16 m t n = a + (n-1) d 11.16 = 7.56 + (n-1) (0.09) 3.6 = (n-1) (0.09) n-1 = 3.6/0.09 = 40 n = 41 Sanjitha’s will be able to throw 11.16 m in 41 weeks.
(iii) a = 40; d = 12; n = 15 S n = n / 2 [2a + (n-1) d] Sn = 15 / 2 [2(40) + (15-1) (12)] = 15 / 2 [80 + 168] = 15 / 2 [248] =1860 throws

Q. No. 3) One evening, Kaushik was in a park. Children were playing cricket. Birds were singing on a nearby tree of height 80m. He observed a bird on the tree at an angle of elevation of 45°.
When a sixer was hit, a ball flew through the tree frightening the bird to fly away. In 2 seconds, he observed the bird flying at the same height at an angle of elevation of 30° and the ball flying towards him at the same height at an angle of elevation of 60°.
![math case study examples class 10 cbse class 10 maths important case based questions](https://www.cbseguidanceweb.com/wp-content/uploads/2024/03/Screenshot-2024-03-09-153418.png)
(i) At what distance from the foot of the tree was he observing the bird sitting on the tree?
(ii) How far did the bird fly in the mentioned time?
After hitting the tree, how far did the ball travel in the sky when Kaushik saw the ball?
(iii) What is the speed of the bird in m/min if it had flown 20(√3 + 1) m?
Ans. i. tan 45° = 80/CE
⇒ 1/√3 = 80/CE
⇒ CE = 80√3
Distance the bird flew = AD = BE = CE-CB = 80√3 – 80 = 80(√3 -1) m
tan 60° = 80/CG
⇒ √3 = 80/CG
⇒ CG = 80/√3
Distance the ball travelled after hitting the tree =FA=GB = CB -CG
GB = 80 - 80 / √3 = 80 (1- 1 / √3 ) m
iii. Speed of the bird = distance/time = 20(√3 + 1)/2 m/sec = 10(√3 + 1)m/sec = 10(√3 + 1) x 60 m/min = 600(√3 + 1) m/min
Q. No. 4) An interior designer, Sana, hired two painters, Manan and Bhima to make paintings for her buildings. Both painters were asked to make 50 different paintings each.
The prices quoted by both the painters are given below:
- Manan asked for Rs 6000 for the first painting, and an increment of Rs 200 for each following painting.
- Bhima asked for Rs 4000 for the first painting, and an increment of Rs 400 for each following painting.
(i) How much money did Manan get for his 25th painting? Show your work.
(ii) How much money did Bhima get in all? Show your work.
(iii) If both Manan and Bhima make paintings at the same pace, find the first painting for which Bhima will get more money than Manan. Show your steps.
(iii) Sana's friend, Aarti hired Manan and Bhima to make paintings for her at the same rates as for Sana. Aarti had both painters make the same number of paintings, and paid them the exact same amount in total.
How many paintings did Aarti get each painter to make? Show your work.
Ans. i. Notes that the amounts Manan is paid for each painting forms an AP.
Takes a = 6000, d = 200 and n = 25 to find the amount as
6000 + (25 - 1)200 = Rs 10800.
ii. Finds the total amount earned by Bhima as follows:
S 50 = 50/2 [2(4000) + (50 - 1)(400)]
Solves the above expression to find the total amount as Rs 6,90,000.
iii. Frames equation as follows:
6000 + ( n - 1)200 = 4000 + ( n - 1)400
Solves the above equation to find the value of n as 11 .
Writes that, since they both earn the same amount for the 11th painting, as Bhima's increment is more, Bhima gets more money than Manan for the 12th painting.
Assumes that the number of paintings required is n .
Frames equation as follows:
S n (Manan) = S n (Bhima)
=> 𝑛/2 [2(6000) + ( n -1)200] = 𝑛/2 [2(4000) + ( n -1)400]
Solves the equation from step 1 to find n as 21.

Find one possible pair of coordinates of the second arrow's landing mark. Show your work.
(iii) An arrow landed on the boundary and is worth 20 points. The coordinates of the landing mark were of the form ( m , - m ).
Find all such coordinates. Show your steps.
Ans. i. Writes two pairs of possible coordinates such that Rohan scored 20 and 5 points for them. For examples, (1.5, 0) and (3.5, 0).
ii. Finds the distance of (2, 2.5) from (0, 0) as:
√(4 + 6.25) = √10.25 units
Hence, concludes that 5 points will be awarded.
iii. Finds the distance of (1.2, 1.6) from the origin as:
√{(1.2) 2 + (1.6) 2 } = 2 units
Assumes that the second arrow lands on the boundary mark and writes that the ratio in which the first arrow divides the origin and the second arrow's landing mark is the ratio of their radii = 2:1.
Assumes the coordinates of the second arrow's landing mark as ( x , y ) and uses section formula to write:
(2𝑥+0/3 , 2𝑦+0/3) = (1.2, 1.6)
Solves the above equation to find the values of the coordinates of the second arrow's landing mark as (1.8, 2.4).
Identifies the distance between the origin and the coordinate ( m , -m ) as 2 units and uses the distance formula to write the equation as:
m 2 + (- m ) 2 = 22
Simplifies the above equation as 2 m 2 = 4.
Solves the above equation to get y as √2 and (-√2).
Finds the coordinates as (√2, -√2) and (-√2, √2)

(Note: Take √3 as 1.73.)
Ans. Assumes the vertical distance between the top of the tree and the drone to be h and finds h as:
h = 5√3 × tan 30° = 5√3 × 1/√3 = 5 m
Finds the height of the tree as 100 - 65 - 5 = 30 m
![math case study examples class 10](https://www.cbseguidanceweb.com/wp-content/uploads/2024/03/Screenshot-2024-03-09-161844-1.png)
Finds the value of θ as:
tan θ = 30√3/30 = √3
Thus finds the value of θ as 60°
iii. Assumes the horizontal distance between the remote and the drone as x and finds its value as:
x = 50√3/tan60° = 50 m
Finds the distance covered by the jeep in 2 mins as:
10 × 120 = 1200 m
Finds the horizontal distance covered by the drone before it stopped as:
1200 + 50 = 1250 m
Finds the speed of the drone as:
1250/120 = 10.42 m/s
Assumes the horizontal distance between the drone and the tiger to be x when the angle of depression was 30° and finds the value of x as:
x = 54√3 × tan 30° = 54√3 × 1/√3 = 54 m
Assumes the horizontal distance between the drone and the tiger after 3 seconds as y and finds the value of y as:
y = 54√3 × tan 45° = 54√3 m
Finds the distance covered by the tiger in 3 seconds as:
54√3 - 54 = 39.42 m
Finds the average speed of the tiger during that time as:
39.42/3 = 13.14 m/s
Q. No. 7) Shown below is the trophy shield Akshi received on winning an international Table tennis tournament. The trophy is made of a glass sector DOC supported by identical wooden right triangles ∆ DAO and ∆ COB. Also, AO = 7 cm and AO : DA = 1 ∶ √3 (Use √3 = 1.73)
![math case study examples class 10](https://www.cbseguidanceweb.com/wp-content/uploads/2024/03/Screenshot-2024-03-09-162746.png)
Based on the given information, answer the following questions:
(i) Find ∠𝐷𝑂𝐶
(ii) Find the area of the wooden triangles
(iii) Find the area of the shape formed by the glass portion
If Akshi wants to decorate the boundary of the glass portion with glitter tape, then find the length of the tape she needs.
Ans. (i) Let ∠𝐷𝑂𝐴 = 𝜃, then tan 𝜃 =𝐴𝐷/𝐴𝑂 = √3/1 ⟹ 𝜃 = 60° ∠𝐷𝑂𝐴 = ∠𝐶𝑂𝐵 = 60° ∠𝐷𝑂𝐶 = 180° − (60° + 60°) = 60°
(ii) Area of two wooden triangles = 2 × 1/2 × 7 × 7√3 = 84.77 𝑐𝑚 2 (iii) 𝐴𝑂/𝐷𝑂 = cos 60° ⟹ 7/𝐷𝑂 = 1/2 ⟹ 𝐷𝑂 = 14 𝑐𝑚 Area of sector 𝐷𝑂𝐶 = 60/360 × 𝜋 × 14 2 = 102.67 𝑐𝑚 2
𝐴𝑂/𝐷𝑂 = cos 60° ⟹ 7/𝐷𝑂 = 1/2 ⟹ 𝐷𝑂 = 14 𝑐𝑚 Length of tape required = 2 × 14 + 60/360 × 2 × 𝜋 × 14 = 42.67 cm
Q. No. 8) A school auditorium has to be constructed with a capacity of 2000 people. The chairs in the auditorium are arranged in a concave shape facing towards the stage in such a way that each succeeding row has 5 seats more than the previous one.
![math case study examples class 10](https://www.cbseguidanceweb.com/wp-content/uploads/2024/03/Screenshot-2024-03-09-163408.png)
(i) If the first row has 15 seats, then how many seats will be there in 12 th row?
(ii) If there are 15 rows in the auditorium, then how many seats will be there in the middle row?
(iii) If total 1875 guests were there in the auditorium for a particular event, then how many rows will be needed to make all of them sit?
If total 1250 guests were there in the auditorium for a particular event, then how many rows will be left blank out of total 30 rows?
Ans. (i) 𝑎 = 15, 𝑑 = 5
𝑎 12 = 15 + 11×5 = 70
(ii) 𝑛 = 15
Middle row = 8th row
𝑎8 = 15 + 7 × 5 = 50
(iii) 1875 = 𝑛/2 [2 × 15 + (𝑛 − 1) × 5]
⟹ 𝑛 2 + 5𝑛 − 750 = 0
⟹ (𝑛 + 30)(𝑛 − 25) = 0 ⟹ 𝑛 = 25
∴ Total number of rows required = 25
1250 = 𝑛/2 [2×15 +(𝑛 − 1) × 5]
⟹ 𝑛 2 + 5𝑛 − 500 = 0
(𝑛 + 25)(𝑛 − 20) = 0 ⟹ 𝑛 = 20
∴ Number of rows left = 30 − 20 = 10
Q. No. 9) The students of Class X of a secondary school have been allotted a rectangular plot of land for their gardening activity. Saplings are being planted on the boundary at a distance of 1 m from each other. There is a triangular grassy lawn in the plot as shown in the figure. The students are to row seeds of the flowering plant on the remaining area of the plot.
![math case study examples class 10](https://www.cbseguidanceweb.com/wp-content/uploads/2024/03/Screenshot-2024-03-09-163933.png)
(i) If a tree is to be planted exactly in the middle of the triangle PQR ie. at the centroid of ∆PQR to give shed to the people sitting in the lawn, then find the coordinates of the point where the tree should be planted.
(ii) What type of triangle is formed by the grassy lawn?
(iii) Find the area of the plot in which the students have to row the seeds.
If a special flowering plant has to be planted at a point which divides the line joining the points C and Q in the ratio 2:3, then find the coordinates of the point where this plant will be planted
Ans. (i) 𝑃(3,3), 𝑄(8,2), 𝑅(6,5)
Coordinates of required point are ( 3+8+6/3, 3+2+5/3) = ( 17/3 , 10/3 )
(ii) 𝑃𝑅 = 𝑄𝑅 = √13
𝑃𝑄 2 = 𝑃𝑅 2 + 𝑄𝑅 2
∴ ∆ 𝑃𝑄𝑅 is an isosceles right triangle
(iii) Area of the plot to row seeds = 13 × 9 − 1/2 × √13 × √13 = 110.5 𝑚
Coordinates of required point are ( 2×8 + 3 ×13 / 2+3 , 2×2+3×9 / 2+3 ) = (11, 31/5 )

Quadratic Equations Case Study Questions With answers
Here, we have provided case-based/passage-based questions for Class 10 Maths Chapter 4 Quadratic Equations
Case Study/Passage Based Questions
1)Formation of Quadratic Equation
Quadratic equations started around 3000 B.C. with the Babylonians. They were one of the world’s first civilizations and came up with some great ideas like agriculture, irrigation, and writing. There were many reasons why Babylonians needed to solve quadratic equations. For example to know what amount of crop you can grow on the square field. Now represent the following situations in the form of a quadratic equation.
The sum of squares of two consecutive integers is 650. (a) x 2 + 2x – 650 = 0 (b) 2x 2 +2x – 649 = 0 (c) x 2 – 2x – 650 = 0 (d) 2x 2 + 6x – 550 = 0
Answer: (b) 2×2 +2x – 649 = 0
The sum of two numbers is 15 and the sum of their reciprocals is 3/10. (a) x 2 + 10x – 150 = 0 (b) 15x 2 – x + 150 = 0 (c) x 2 – 15x + 50 = 0 (d) 3x 2 – 10x + 15 = 0
Answer: (c) x2 – 15x + 50 = 0
Two numbers differ by 3 and their product is 504. (a) 3x 2 – 504 = 0 (b) x 2 – 504x + 3 = 0 (c) 504x 2 +3 = x (d) x 2 + 3x – 504 = 0
Answer: (d) x2 + 3x – 504 = 0
A natural number whose square diminished by 84 is thrice of 8 more of a given number. (a) x 2 + 8x – 84 = 0 (b) 3x 2 – 84x + 3 = 0 (c) x 2 – 3x – 108 = 0 (d) x 2 –11x + 60 = 0
Answer: (c) x2 – 3x – 108 = 0
A natural number when increased by 12, equals 160 times its reciprocal. (a) x 2 – 12x + 160 = 0 (b) x 2 – 160x + 12 = 0 (c) 12x 2 – x – 160 = 0 (d) x 2 + 12x – 160 = 0
Answer: (d) x2 + 12x – 160 = 0
2)Nature of Roots A quadratic equation can be defined as an equation of degree 2. This means that the highest exponent of the polynomial in it is 2. The standard form of a quadratic equation is ax 2 + bx + c = 0, where a, b, and c are real numbers and a ≠ 0. Every quadratic equation has two roots depending on the nature of its discriminant, D = b 2 – 4ac
Which of the following quadratic equation have no real roots? (a) –4x 2 + 7x – 4 = 0 (b) –4x 2 + 7x – 2 = 0 (c) –2x 2 +5x – 2 = 0 (d) 3x 2 + 6x + 2 = 0
Answer: (a) –4×2 + 7x – 4 = 0
Which of the following quadratic equation have rational roots? (a) x 2 + x – 1 = 0 (b) x 2 – 5x + 6 = 0 (c) 4x 2 – 3x – 2 = 0 (d) 6x 2 – x + 11 = 0
Answer: (b) x2 – 5x + 6 = 0
Which of the following quadratic equation have irrational roots? (a) 3x 2 +2x + 2 = 0 (b) 4x 2 – 7x + 3 = 0 (c) 6x 2 – 3x – 5 = 0 (d) 2x 2 +3x – 2 = 0
Answer: (c) 6×2 – 3x – 5 = 0
Which of the following quadratic equations have equal roots? (a) x 2 – 3x + 4 = 0 (b) 2x 2 – 2x + 1 = 0 (c) 5x 2 – 10x + 1 = 0 (d) 9x 2 + 6x + 1 = 0
Answer: (d) 9×2 + 6x + 1 = 0
Which of the following quadratic equations has two distinct real roots? (a) x 2 + 3x + 1 = 0 (b) –x 2 + 3x – 3 = 0 (c) 4x 2 + 8x + 4 = 0 (d) 3x 2 + 6x + 4 = 0
Answer: (a) x2 + 3x + 1 = 0

SCALE FACTOR
Case study:
A scale drawing of an object is the same shape at the object but a different size. The scale of a drawing is a comparison of the length used on a drawing to the length it represents. The scale is written as a ratio. The ratio of two corresponding sides in similar figures is called the scale factor
Scale factor= length in image / corresponding length in object
If one shape can become another using revising, then the shapes are similar. Hence, two shapes are similar when one can become the other after a resize, flip, slide or turn. In the photograph below showing the side view of a train engine. Scale factor is 1:200
This means that a length of 1 cm on the photograph above corresponds to a length of 200cm or 2 m, of the actual engine. The scale can also be written as the ratio of two lengths.

Case Study Questions on Lines and Angles
A math’s teacher was teaching students about intersecting lines.
Suppose AB and CD are two intersecting lines, which meets at point O. In this point O, she draw a line OE and all these lines were making different angles with each other.
![math case study examples class 10](https://xamcontent.com/wp-content/uploads/2024/08/image-24.png)
After explaining the description of the figure, she asked the following questions from the students.
On the basis of the above information, solve the following questions.
Q 1. Find the measure of ∠BOD.
Q 2. Check whether pair of angles ∠AOC and ∠BOC makes a linear pair.
Q 3. Which of the following angles form a non collinear lines? (i) A, O, B (ii) C, O, E
Q 4. Find the measure of ∠AOE.
1. From figure,
$$ \angle B O D=\angle A O C=35^{\circ} $$
[Vertically opposite angles]
2. From figure, it is clear that
$$ \angle A O C+\angle B O C=180^{\circ} $$
$[\because A B$ is a straight line $]$ Hence, $\angle A O C$ and $\angle B O C$ makes a linear pair.
3. (i) It is clear from the figure that points $A, O$ and $B$ form a collinear points. (ii) It is clear from the figure that points $\mathrm{C}, \mathrm{O}, \mathrm{E}$ forms a non-collinear points.
Hence, points C, O, E form a non-collinear line.
4. From the given figure, $C D$ is a line segment.
Therefore, the sum of all angles of the same side of a line is $180^{\circ}$.
$$ \begin{aligned} & \therefore \angle \mathrm{COA}+\angle \mathrm{AOE}+\angle \mathrm{EOD}=180^{\circ} \\ & \Rightarrow 35^{\circ}+\angle A O E+75^{\circ}=180^{\circ} \\ & \Rightarrow \angle \mathrm{AOE}=180^{\circ}-110^{\circ} \\ & =70^{\circ} \end{aligned} $$
Understanding Lines and Angles
Line: A geometrical object that is straight and extends indefinitely in both directions. Line Segment: A part of a line with two end points. Ray: A part of line with one end point. Collinear Points: Three or more points lying on the same line are known as collinear points. Otherwise, they are non-collinear points. Angle: It is formed when two rays originate from the same end point. The rays are called arms and the end point is called vertex.
Types of Angles:
![math case study examples class 10](https://xamcontent.com/wp-content/uploads/2024/08/image-25.png)
- Acute Angle: An angle with measure more than 0° but less than 90°. In figure, ∠AOB is acute angle.
- Obtuse Angle: An angle with measure more than 90° but less than 180°. In figure, ∠AOD is obtuse angle.
- Right Angle: An angle with measure exactly 90°. In figure, ∠AOC is right angle.
- Straight Angle: An angle with measure 180°. In figure, ∠AOE is straight angle.
- Reflex Angle: An angle with measure more than 180° but less than 360°. In figure, ∠AOF is reflex angle, when measured anticlockwise.
- Complete Angle: An angle with measure 360°. In figure, ∠AOA is complete angle.
Pair of Angles:
![math case study examples class 10](https://xamcontent.com/wp-content/uploads/2024/08/image-26.png)
- Complementary Angles: Two angles with the sum of 90°. In above figure, ∠AOB + ∠BOC = 90°, so ∠AOB and ∠BOC are complementary angles.
- Supplementary Angles: Two angles with the sum of 180°. In above figure, ∠AOB + ∠BOE = 180°, so ∠AOB and ∠BOE are supplementary angles
- Adjacent Angles: Two angles having a common vertex and a common arm with uncommon arms on either side of the common arm. In figure, ∠AOC and ∠BOC are adjacent angles. OR When two angles are adjacent, then their sum is always equal to the angle formed by the two non-common arms. In figure, ∠AOB = ∠AOC + ∠BOC
- Linear Pair of Angles: Two adjacent angles with the sum of 180°. In figure, ∠AOC and ∠BOC are linear pair of angles.
![math case study examples class 10](https://xamcontent.com/wp-content/uploads/2024/08/image-27.png)
Vertically Opposite Angles: The pair of angles lying on the opposite sides of the point of intersection. In figure, (∠AOC and ∠BOD) and (∠AOD and ∠BOC) are pairs of vertically opposite angles.
![math case study examples class 10](https://xamcontent.com/wp-content/uploads/2024/08/image-28.png)
Bisector of an Angle: A ray which divides an angle into two equal parts.

Frequently Asked Questions (FAQs) on Lines and Angles Case Study
Q1: what are the different types of angles.
A1: Angles are classified based on their measures: Acute Angle : Measures less than 90°. Right Angle : Measures exactly 90°. Obtuse Angle : Measures more than 90° but less than 180°. Straight Angle : Measures exactly 180°. Reflex Angle : Measures more than 180° but less than 360°.
Q2: What are complementary and supplementary angles?
A2: Complementary Angles : Two angles are complementary if their sum is 90°. Supplementary Angles : Two angles are supplementary if their sum is 180°.
Q3: What is a linear pair of angles?
A3: A linear pair of angles is formed when two adjacent angles add up to 180°. The angles in a linear pair are always supplementary.
Q4: What is the Angle Sum Property of a Triangle?
A4: The Angle Sum Property states that the sum of the interior angles of a triangle is always 180°.
Q5: What are parallel lines and a transversal?
A5: Parallel Lines : Two lines that are equidistant from each other and never intersect. Transversal : A line that intersects two or more lines at distinct points. When a transversal cuts through parallel lines, it forms angles with specific relationships, like corresponding, alternate interior, and alternate exterior angles.
Q6: What is the significance of corresponding angles when a transversal intersects parallel lines?
A6: When a transversal intersects two parallel lines, the corresponding angles formed are equal. This property helps in proving that the lines are parallel and in solving various geometrical problems.
Q7: Are there any online resources or tools available for practicing Lines and Angles case study questions?
A8: We provide case study questions for CBSE Class 9 Maths on our website. Students can visit the website and practice sufficient case study questions and prepare for their exams.
