Question
A and B together can finish a task in 35 days. If B is
40% more efficient than A, how many days will it take for B alone to complete the task?Solution
Let the amount of work done by A alone in one day be ‘x’ units So the amount of work done by B alone in one day = 1.4x units So the total work = 35 × (x + 1.4x) = 84x units Time taken by B alone to complete the work = 84x/1.4x = 60 days
