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:

915

x = Number of employees in A = 64.2º

y = Number of employees in C & E = 72º + 93º = 165º

y - 2x = 165º - 2 × 64.2º = 36.6º

=   \(\frac{ 36.6º}{ 360º}\) × 9000

= 915
