Question
Aman is twice as efficient as Suman. Both of them began
working together, but Aman stopped after 12 days. Suman then finished the remaining work in 4 days. Determine the time it would take Aman to complete the entire work on his own.Solution
Let the efficiency of Suman be '1e' unit/day Efficiency of Aman = 2 X 1e = '2e' units/day Total work = (1e + 2e) X 12 + 4 X 1e = 36e + 4e = 40e units Therefore, required time = (40e/2e) = 20 days
