‘A’ and ‘B’ can complete a certain work in 12 days and 24 days, respectively. They started working together and worked till completion of the work for which they got Rs. 24000 as wage. Find the share of ‘B’ out of total wage.
Let total work = 24 units {LCM of (12 and 24)} Efficiency of ‘A’ = 24/12 = 2 units/day Efficiency of ‘B’ = 24/24 = 1 units/day Wages received by ‘A’ and ‘B’ will directly proportion to their efficiency. So share of ‘B’ = 24000 × (1/3) = Rs 8000
