Work done by X in 8 days = 1 x 8 = 1 . 40 5 Remaining work = 1 - 1 = 4 . 5 5 Now, 4 work is done by Y in 16 days. 5 Whole work will be done by Y in 16 x 5 = 20 days. 4 X's 1 day's work = 1 , Y's 1 day's work = 1 . 40 20 (X + Y)'s 1 day's work = 1 + 1 = 3 . 40 20 40 Hence, X and Y will together complete the work in 40 = 13 1 days. 3 3
