percentage question

[Guest]

In July 1st last year, the number of employees at a company decreased by 10%, so management raised the salary amount by 10% in August after the decrease in the number of employees.
The total of the combined salaries of all employees after July 1st this year was what percent of that before July 1st last year?

Answer choices: 90, 99, 100, 101, 110

My answer: 99%. Not sure about it. The way I solved this question was by plugging in values: I assumed the number of employees last year was 100, and that the pay was $11.00/hour.

Can you please let me know if my answer is correct.

Thanks! :wink:

Correct!
Salary amount doesn't matter (a buck a year will do!);
but must assume all employees earn same amount.
