I'm new to this community, what do you suggest is the best way for me to post my questions? I need lots of help with quant. Should I find a thread to post my question or is there a general place to place your questions. Below is a sample of a question, where would place this?

Of the 3,600 employees of Co X, 1/3 are clerical. If the clerical staff were to be reduced by 1/3, what percent of the total number of the remaining employees would then be clerical?

ANS

A) 25%

B) 22.2%

C) 20%

D) 12.5%

E) 11.1%

MY ISSUE IS FINDING A QUICK METHOD TO COMPUTE THIS PROBLEM

The figure 3600 is misleading. Since the answer demands percentages and the statements use ratio, we can pick any number to our convenience.

For easier calculation take 36

So clerical employees left = 36 x 1/3 x 1/3 = 4

Remaining clerical employees = 36 x 1/3 - 4 = 8

Total employees left = 36-4 = 32

Req percentage = (Remaining clerks/Total remaining employees)*100 = 8/32*100 = 25%
