If everyone types at the same rate, three.
6. One typist types one page in two minutes.
Assuming the typists all type at the same speed...Two typists typing two pages in five minutes means it takes 1 typist five minutes to produce 1 page.In ten minutes, each typist could produce two pages. So to produce twenty pages in that time, you'll need ten typists.

12 pages in 6 minutes = 2 pages per minute. 96 pages at 2 pages per minute = 96/2 = 48 minutes.

If two typists type 2 pages in 5 minutesIn 1 minute they will type 2/5pagestherefore 2 typists type 2/5 pages in 1 minute1 typist will type (2/5)/2 pages in 1 minute(he will type less)=1/5 pages.... eqn 1x typists type 20 pages in 10 minutesin 1 minute they will type 20/10 pages=2 pagestherefore x typists type 2 pages in 1 minute1 typist will type 2/x pages............eqn 2equating eqn 1 and 2 gives 2/x=1/5therefore x =10 typists
It will take 48 minutes to proofread 96 pages. Since you can proofread 12 pages in 6 minutes, you can proofread 96 pages in 48 minutes (12 pages x 8 = 96 pages).

12 pages in 6 minutes = 2 pages per minute. 96 pages at 2 pages per minute = 96/2 = 48 minutes.
It will take 96/12 = 8 and 8 times 6 = 48 minutes

If 100 pages are printed in 5 minutes, then 50 pages would take half the time, which is 2.5 minutes.
It will take 48 minutes.
