‘A’ can do a piece of work in 15 days. ‘B’ can do 80% of the same work in 20 days. If they work together for the entire time and get paid Rs.1408, then find the share of ‘A’.
Let the total work be 60 units. (LCM of 15 and 20) Efficiency of A = 60/15 = 4 units/day Efficiency of B = (60/20) × (80/100) = 12/5 units/day Ratio of the efficiency of A : B = 4 : 12/5 = 5:3 Share of A = (5/8) × 1408 = Rs.880
