Anil can do a piece of work in 25 days. He alone worked
at it for 10 days and then Sunil completed alone the rest work in 15 days. In how many days, they will complete the whole work, working together?Solution
Efficiency of Anil = 100/25 = 4% Work done by Anil in 10 days = 10/25 × 100 = 40% Remaining work = 60% Efficiency of Sunil = 60/15 = 4% Therefore, required number of days = 100/((4+4)) = 100/8 = 12(1/2) days   Â
