The total of the combined salaries of all the employees at Company E after the layouts was what percent of that before the layouts?
90%
99%
100%
101%
110%
Let the original number of employees = 10.
Let the original average salary = 10.
Sum of the salaries = number*average = 10*10 = 100.
Number of employees decreased by 10% = 9.
Average salary increased by 10% = 11.
New sum = number*average = 9*11 = 99.
New sum/Original sum = 99/100 = 99%.
The correct answer is
B.
