A can copy 50 papers in 10 hours while both A & B can copy
70 papers in 10 hours. Then for how many hours
required for B to copy 26 papers?

Answer Posted / apoorva

A can copy 50pages in 10hrs;
B can copy 70 pages in 10hrs;
Both A And B togethr ie (A+B) can copy 70 pgs in 10hrs;
which means B alone can copy 20 pages in 10 hrs (since A can copy 50pages in 10hrs;) ie (B-A)

hence if B can copy 20 pages in 10 hrs then in 24 hrs he can copy ((26*10)/20) = 13 hrs
