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:
Answer & explanation
Correct answer: option 4
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
