Question
A and B can complete a task together in 14 days, while B
alone takes 28 days to finish it. A began working alone and left after ‘x’ days, after which B completed the remaining work in 21 days. Determine the percentage of the total work completed by A.Solution
Let total amount of work be 28 units
Efficiency of (A + B) = 28/14 = 2 units/day
Efficiency of ‘B’ = 28/28 = 1 unit/day
Amount of work done by ‘B’ = 21 × 1 = 21 units
Percentage of work done by ‘A’ = {(28 – 21)/28} × 100 = 25%
