B....

# of people before = 100
salary before = 10
Total salary = 1000

# of people after = 90
salary after = 11
Total salary = 990

% = 990/1000 = 99%

Let x be he number of employees before July 1st
And A be the average salary
Then total = xA

After July 1st , number of employees = 9x/10
And Average salary is =11A/10

New total = 99xA/100

Percent = 99xA/100/xA * 100 = 99
