Question
A work can be completed by ‘A’ and ‘B’, alone in
10 days and 15 days, respectively. Find the number of days taken by ‘C’ to complete the same work alone if ‘A’, ‘B’ and ‘C’ together can complete the whole work in 3 days.Solution
Let total work = 30 units (LCM of 10 and 15) Efficiency of ‘A’ = (30/10) = 3 units/day Efficiency of ‘B’ = (30/15) = 2 units/day Combined efficiency of ‘A’, ‘B’ and ‘C’ = (30/3) = 10 units/day Efficiency of ‘C’ = 10 – (3 + 2) = 5 units/day Required time taken = (30/5) = 6 days
