Very good post.

There is a mistake thought in the answers. In Question 15 the correct answer is C not A.

Re: Collections of work/rate problem with solutions [#permalink] New post 03 Jan 2012, 04:20
Wonderful collection. thanks much -
I wonder if the answer to 2nd might need a change:
I get 3*(W/T+W/T-2) = 6W*(T-1)/(T*(T-2))... that leads to a quadratic
5T*T -34T+ 24 =0... hence T=5.
So answer would be D (2W corresponds to 2T=10 days)
Does that sound ok?
