assuming each of the first 2 typist each type a page per minute, and not one type 1 and a 1/2 and the other type 1/2. you only need one of them for 18 pages in 18 minutes

if 2 typists type 2 pages in 2 minutes, then 1 will type 1 page in 2 mins. It will therefore take 1 typist 36 mins to type 18 pages, and therefore it will take 2 typists 18 mins to type 18 pages.

Unless there is a trick in the wording, and 2 typists type 2 pages each in 2 minutes, then 1 will type 1 page in 1 minute, and 1 will type 18 pages in 18 minutes.

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


Actually, I don't think there is enough information to solve to problem. We need to know how many typewriters are present.

If there is only one typewriter, then each typist typed 1 page in 1 minute. Therefore a single typist could do 18 pages in 18 minutes.

However, if there were 2 typewriters available, then it took each typist 2 minutes to type 1 page each. It would be impossible for any number of such typists to type 18 pages in 18 minutes.

It really doesent matter. two typists in two minutes= 1 typist in 1 minute. therefore the only possible answer is one, because only one typist could type 18 pages in 18 minutes.

2 typist.2 can write 2 pages for 2 min,i.e. 2 typist write with the speed of 1 page/min,i.e. 2 typist will write 18 pages for 18 min.

are you quoting someone or are your just throwing your net wide to cover all the basis? :lol:

Anyway, I believe the math work out to 1 typist typing 1 page in 2 mins or .5ppm. Adding a typist will take you to 2 pages in 2 mins, or a factor of two. It will not take you to a factor of 4 and cut your time in half as well. So the end answer is that it will take 2 typists to type 18 pages in 18 mins.

Just depends on how you look at it...

An answer to this would be nice.

The answer is the one and only one.



so u say that 1 can type 1 page in 1 minute, So lets prove back the puzzle then

1st Typist-> Typed 1 page in 1 minute
2nd typist-> Typed 1 more page in same one minute.

So 2 typists can type 2 pages in 1 minute :P

So it must be one and only two :lol:
