Study the pie-chart and answer the question.

Distribution (degree-wise) of the number of employees of a company working in 5 departments A,B,C,D and E.

If the total number of employees working in departments A and B exceeds the number of employees in department C by x, then x lies between:

120 and 140

Difference in  number of employee in department  A & B together to employee in department C = \(\frac{(79.2+57.6) - 122.4}{360}\) × 3200

= \(\frac{(14.4}{360}\) × 3200

= 128

Ans = 120 & 140
