Let the original number of employees = 10.On July 1 of last year, total employees at company E was decreased by 10%. Without any change in the salaries of the remaining employees, the average 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 the employees at Company E after July 1 last year was what percent of that before July 1 of last year?
90
99
100
101
110
Let the original average salary = 10.
Then:
Original combined salaries = number*average = 10*10 = 100.
Number of employees decreased by 10% = 9.
Average salary increased by 10% = 11.
New combined salaries = number*average = 9*11 = 99.
Resulting ratio:
(new combined salaries)/(original combined salaries) = 99/100 = 99%.
The correct answer is B.
