‘A’ can do a piece of work in 20 days. ‘B’ can
do 80% of the same work in 30 days. If they work together for the entire time and get paid Rs.1610, then find the share of ‘A’.Solution
Let the total work be 60 units. (LCM of 20 and 30) Efficiency of A = 60/20 = 3 units/day Efficiency of B = (60/30) × (80/100) = 8/5 units/day Ratio of the efficiency of A : B = 3 : 8/5 = 15:8 Share of A = (15/23) × 1610 = Rs.1050
