Without any changes in the salaries of remaining employees, the average ( mean) employee salary was 10% more after the decrease in the number of employees than before the decrease. The total of the combined salaries of all of the employees at company E after july 1 last year was what percent of that before july 1 last year?
a. 90%
b. 99%
c. 100%
d. 101%
e. 110%
Before July 1:
Let the number of employees = 10 and the original salary per employee = 10.
Sum = 10*10 = 100.
After July 1:
The new number of employees = 9 (10% fewer than before July 1).
The new salary per employee = 11 (10% more than before July 1).
New sum = 9*11 = 99, which is 99% of the old sum of 100.
The correct answer is
B.
