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?

Hi,

Im an L here, sorry for late response.

the result of the 2nd degree equation you report is incorrect. The correct result is T=6, thus, the Job of 2W would be done in 6*2=12 days which leads us to the answer E.

Rgds,
