Question
‘A’ and ‘B’ can do a piece of work in 17 days
and 34 days, respectively. They started working together but ‘A’ left after 4 days. Find the time taken by ‘B’ to complete the remaining work.Solution
Let total amount of work be 34 units (LCM of 17 and 34). Efficiency of ‘A’ = 34/17 = 2 units/day Efficiency of ‘B’ = 34/34 = 1 units/day Amount of work done by ‘A’ and ‘B’ together in 4 days = (2 + 1) × 4 = 12 units Time taken by B to complete remaining work = {(34 – 12)/1} = 22 days
