OK if two typest type 2 pages in 2 min, that means that they each are typing 1 page every two min. So in order to type 18 pages in 18 min you would need 36 typists.

If 2 are typing at the same time for 2 minutes and finish with 2 pages, and assuming they are equal then each did, in fact, take 2 minutes to type one page. At this rate, in 18 minutes each will have typed 9 pages. 9x2=18. It has to be 2 by this thinking.

36 would type 36 pages in 2 minutes with this logic, if everyone is typing 1 page every 2 minute.

If we count in the terms of typist-minute (like some people use man-day), it will be 2x2=4 typist-minute for 2 pages.
So for 18 pages you need 18/2 x 4 = 36 typist-minute

Since you are given 18 minutes, the number of typist you need = 36/ 18 = 2 typist.

As simple as 2. :D

2 typist can type 2 pages in 2 minutes, so each is typing .5 pages a minite, so in 18 minutes each would type 9 pages both of them together would type the 18 pages.

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



hmm well i know its too late to p0st my idea regarding this matter, but im just a new member here and as i viewed their comments about your post, m0st 0f them didnt s0lve this l0gically, well i h0nestly g0t ur answer f0r 2 minutes, and in fact its s0 easy, from the statement " two typists ca type two pages in two minutes means that 0ne typist can type 0ne page for two minutes.So the answer is 6 right?...t0 th0se wh0 cann0t get the explanati0n, well you need s0me meds to enhace your brain.

I) Problem: h0w many typists will it take to type 18 pages in two minutes:

since the answer is 0bviously stated ab0ve, that the two typists can type two pages in two minutes;
therefore the answer wud be 6.
shows that:

1 typist = 1 page for 2 minutes
1 typist = 3 pages for 6 minutes
2 typists = 6 pages for 6 minutes
3 typists = 9 pages for 6 minutes
4 typists = 12 pages for 6 minutes
5 typists = 15 pages for 6 minutes
6 typists = 18 pages for 6 minutes

well i agree that 1 typist can type .5 in 0ne minute,therefore 1 typist can type 3 pages in 6 minutes right? ( 1typist * .5page *6minutes = 3 pages )
so, if there are 6 typists, they can produced 18 pages in 6 minutes. ( 6typists * .5page * 6minutes = 18 pages )
