Question
‘A’ can do a piece of work in 10 days. ‘B’ can
do 80% of the same work in 20 days. If they work together for the entire time and get paid Rs.1400, then find the share of ‘A’.Solution
Let the total work be 20 units. (LCM of 10 and 20) Efficiency of A = 20/10 = 2 units/day Efficiency of B = (20/20) × (80/100) = 4/5 units/day Ratio of the efficiency of A : B = 2 : 4/5 = 10:4 Share of A = (10/14) × 1400 = Rs.1000
