Krishna can do a piece of work in 25 days. He alone
worked at it for 10 days and then Balram completed alone the rest work in 20 days. In how many days, they will complete the whole work, working together?Solution
Efficiency of Krishna = 100/25 = 4% Work done by Krishna in 10 days = 10/25 × 100 = 40% Remaining work = 60% Efficiency of Balram = 60/20 = 3% Therefore, required number of days = 100/((4+3)) = 100/7 = 14(2/7) days
