Question
A and B can complete a task together in 18 days, while B
alone takes 36 days to finish it. A began working alone and left after ‘x’ days, after which B completed the remaining work in 27 days. Determine the percentage of the total work completed by A.Solution
Let total amount of work be 36 units
Efficiency of (A + B) = 36/18 = 2 units/day
Efficiency of ‘B’ = 18/18 = 1 unit/day
Amount of work done by ‘B’ = 27 × 1 = 27 units
Percentage of work done by ‘A’ = {(36 – 27)/36} × 100 = 25%
