Question
A can copy 60 pages in 15 hours, A and B together can
copy 126 pages in 21 hours. Then in how many hours B can copy 12 pages.Solution
Number of pages copied by x in hour = 60/15 = 4
Number of pages copied by x and y in 1 hour = 126/21 = 6
∴ Number of pages copied by y in 1 hour = 6 – 4 = 2
∴ Required time = 2 x 12 = 24 hours.
