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

What is the number of offices in which the number of employees of the company is between 350 and 650?

1 employee = $$\frac{360}{2400}$$
350 employees = $$\frac{360}{2400} \times 350$$ = 52.5$$\degree$$
650 employees = $$\frac{360}{2400} \times 650$$ = 97.5$$\degree$$
Number of offices in which the number of employees of the company is between 350 and 650 = number of offices in which the number of employees of the company is between 52.5$$\degree$$ and 97.5$$\degree$$
= 3 offices
$$\therefore$$ The correct answer is option D.
