Time and Work
A and B together complete a work in 12 days. A alone works 8 days and B completes the remaining work in 20 days by doing it alone. In how much time will A alone finish the whole work? |
18 days 36 days 24 days 16 days |
18 days |
According to the question if A does not work 4 days, B has to work 8 days extra to finish the work". So, ⇒ 4 days of A's work = 8 days of B's work Ratio of efficiency = A : B = 2 : 1 Total Work = 12 x 3 = 36 A alone will complete the work in = 362 = 18 days |
