The pie graph shows the distribution of employees working in five departments A, B, C, D and E of a company. Total number of employees = 9000 If the number of employees working in department A is x and the total number of employees working in departments C and E is y, then the value of y - 2x is: Correct Answer 915

The number of employees working in department A = (64.2/360) × 9000 = 1605 

The total number of employees working in departments C and E = {(72 + 93)/360} × 9000 = 4125

Then,

y - 2x

⇒ 4125 - 2 × 1605
⇒ 4125 - 3210
⇒ 915

∴ If the number of employees working in department A is x and the total number of employees working in departments C and E is y, then the value of y - 2x is 915.
