The pie chart given below shows the number of students studying in 5 sections of a class. The data is presented in the terms of degrees.
Total number of students studying in section C and D = 400.
What is the difference between the number of students studying in section C and A?
Show answer & explanation
Correct answer: A
Explanation
A = 72°, B = 144°, C = 108°, D = 12°, E = 24°
Students in C + D = 400
C + D = 108° + 12° = 120°
120° → 400 students
1° → 400 / 120 = 10/3
Students in A = 72 × (10/3) = 240
Students in C = 108 × (10/3) = 360
Difference = 360 − 240 = 120
