# Typists problem

### #51

Posted 24 April 2008 - 03:52 PM

If two typists can type two pages in two minutes, then one typist can type one page in one minute, which means she can then types a page/minute and would be able then to type 18 pages in 18 minutes since it's still a 1:1 ratio.

It doesn't say that both typists type at the same speed, in one minute, one may only be able to type a half of a page while the other can type a page and a half in the two minute time frame. Un fortunately, since there is no way to tell how fast they type individually, you must keep them together on this one.

Two typists can type two pages in two minutes... it will take two typists to type eighteen pages in eighteen minutes.

Here's the math:

Total Time= (Constant*Number of Pages)/Number of typists

T=KP/Y

2=2K/2

(2=2x/2)*2

(4=2K)/2

K, your constant = 2

Therefore- Total time=2*Number of pages/typists

(18=36/Y)*T

(18Y=36)/18

Y=2

So it will take 2 typists!

Your wrong, the answer is 2. If two typist type 2 pages in 2 minutes then that meant each typist typed one page in a 2 min period meaning that each typist types at a rate of 1 page every 2 mins. in 18 mins each typist would type 9 pages so you would need 2 typist to types 18 pages in 18 mins.If two typists can type two pages in two minutes, then one typist can type one page in one minute, which means she can then types a page/minute and would be able then to type 18 pages in 18 minutes since it's still a 1:1 ratio.

I've heard these many times, and there's a very simple way to solve them.

~~~If you are thinking each typist can type a page a minute, or "2 typists can EACH type two pages in two minutes", then your answer is ONE

~~~If you think each typist can type half a page a minute, or "2 typists can TOGETHER type two pages in two minutes", then your answer is TWO

So EACH (1:1 ratio) = One typist

TOGETHER (2:1 ratio) = Two typists

If two typists can type two pages in two minutes, how many typists does it take to type 18 pages in 18 minutes?

Simply 2 (if one typist can type one page in one minute, etc)

If they are a team and they can do 2 pages in 2 minutes only together then it , then you could say 9, or you could say 18. Depends on perception

think of it as dividing 2 by 2, and dividing 18 by 18... you get the same answer...1

although that had absolutley nothing to do with the answer.

(my 3rd post ever!!! yay.)
