Madhya Pradesh Police Exam Model Paper 3

Given:
A number C is 2 times of the average of A, B and D
The number B is equal to the average of A and D
B = 16
Formula:
Average of n numbers Calculation:
Given that C is 2 times of the average of A, B and D
C=2(A+B+D)/3
⇒3C=2A+2B+2D
Number B is equal to the average of A and D
B=(A+D)/2
⇒2B=A+D
Now,
3C=2A+2B+2D
⇒3C=2(A+D)+2B
⇒ 3C=2(2×16)+(2×16)
⇒3C=64+32
⇒ 3C=96
∴ C = 32
