The given pie chart shows the breakup of total number of the employees of a company working in different offices (A,B, C, D and E).
Total No. of employees = 2400

If 40% of the number of employees in office A are shifted equally to office B and E, then what is the difference between the number of employees in B and that in C?

Employees in office A = 2400 $$\times \frac{126}{360}$$ = 840
40%  employees of office A = 840 $$\times \frac{40}{100} = 336
Number of employee in equal two parts = 336/2 = 168
Employees in office B = 2400 $$\times \frac{18}{360}$$ = 120
Total employees in office B after shifting = 120 + 168 = 288
Employees in office C = 2400 $$\times \frac{54}{360}$$ = 360

Difference between the number of employees in B and that in C = 360 - 288 = 72
