Question
‘A’ and ‘B’ can do a piece of work in 15 days
and 18 days, respectively. They started working together but ‘A’ left after 5 days. Find the time taken by ‘B’ to complete the remaining work.Solution
Let total amount of work be 90 units (LCM of 15 and 18). Efficiency of ‘A’ = 90/15 = 6 units/day Efficiency of ‘B’ = 90/18 = 5 units/day Amount of work done by ‘A’ and ‘B’ together in 5 days = (6 + 5) × 5 = 55 units Time taken by B to complete remaining work = {(90 – 55)/5} = 7 days
