Question
‘A’ and ‘B’ can do a piece of work in 12 days
and 24 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 24 units (LCM of 12 and 24). Efficiency of ‘A’ = 24/12 = 2 units/day Efficiency of ‘B’ = 24/24 = 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 = {(24 – 12)/1} = 12 days
