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:

Number of employees working in department A = x = $$\frac{64.2^{\circ\ }}{360^{\circ\ }}\times9000$$ = 1605

x = 1605

Number of employees working in department C = $$\frac{72^{\circ\ }}{360^{\circ\ }}\times9000$$ = 1800

Number of employees working in department E = $$\frac{93^{\circ\ }}{360^{\circ\ }}\times9000$$ = 2325

The total number of employees working in departments C and E = y = 1800 + 2325 = 4125

y = 4125

y - 2x = 4125 - 2(1605) = 4125 - 3210 = 915

Hence, the correct answer is Option D
