Why do you divide by 3200 (= 3600-400) ?

May be it's due to my english skills and my understanding of "the clerical staff were to be reduced by 1/3" : I thought that the 400 persons were no more clerical but STILL employees of company X !

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%

Hello from the GMAT Club BumpBot!

Thanks to another GMAT Club member, I have just discovered this valuable topic, yet it had no discussion for over a year. I am now bumping it up - doing my job. I think you may find it valuable (esp those replies with Kudos).

Want to see all other topics I dig out? Follow me (click follow button on profile). You will receive a summary of all topics I bump in your profile area as well as via email.

Of the 3,600 employees of Company 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?

(A) 25% (B) 22.2% (C) 20% (D) 12.5% (E) 11.1%

We are given that there are 1/3 x 3,600 = 1,200 clerical employees. If that number is reduced by 1/3, there are now 2/3 x 1,200 = 800 clerical employees. Also, the total number of employees at the company will be reduced from 3,600 to 3,200.

Thus, the new percentage of clerical employees would be 800/(3600 - 400) = 800/3200 = 25%.

Answer: A
