No. of employees before 1st July = X
No. of employees after 1st July = Y
Change in no. of employees = reduced by 10%
So, Y = 0.9X
Avg. salaray before 1st July = P
Avg. salaray after 1st July = Q
Change in avg. salary = increased by 10%
So, Q = 1.1P
Total salary = Average salary x No. of employees
Total salary before 1st July = PX
Total salary after 1st July = QY
So,
QY/PX = (0.9X)(1.1P)/PX = (9/10)(11/10) = 99/100 = 99%
Choose B.
