Question
‘A’ and ‘B’ can complete a certain work in 20
days and 10 days, respectively. They started working together and worked till completion of the work for which they got Rs. 18000 as wage. Find the share of ‘B’ out of total wage.Solution
Let total work = 20 units {LCM of (20 and 10)} Efficiency of ‘A’ = 20/20 = 1 units/day Efficiency of ‘B’ = 20/10 = 2 units/day Wages received by ‘A’ and ‘B’ will directly proportion to their efficiency. So share of ‘B’ = 18000 × (2/3) = Rs 12000
