CGPSC Prelims CSAT 2020 Solved Paper 2

Question Numbers: 7-8

Direction: Study the pie-chart and answer the following questions.

Break-up (degree-wise) of students in terms of specialisation in different areas (A, B, C, D and E) in an MBA program

Total number of student

s = 2100

Question : 8 of 100

Marks: +1, -0

Solution:

Concept:

The pie chart gives angles for each specialisation; convert the angle difference into number of students using the total.

Explanation:

From the pie chart:

\angle A = 61.2^\circ

\angle B = 75.6^\circ

\angle C = 72^\circ

\angle D = 54^\circ

Total students

= 2100

Sum for A and B

= 61.2^\circ + 75.6^\circ = 136.8^\circ

Sum for C and D

= 72^\circ + 54^\circ = 126^\circ

Difference

x

in degrees

= 136.8^\circ - 126^\circ = 10.8^\circ

Since

360^\circ

represents

2100

students:

x = \frac{10.8^\circ}{360^\circ} \times 2100

x = 63

Here,

63

lies between

60

and

65

Answer:

x = 63

, so it lies between

60

and

65
