Question
A and B can complete a task together in 26 days, while B
alone takes 52 days to finish it. A began working alone and left after ‘x’ days, after which B completed the remaining work in 39 days. Determine the percentage of the total work completed by A.Solution
Let total amount of work be 52 units
Efficiency of (A + B) = 52/26 = 2 units/day
Efficiency of ‘B’ = 52/52 = 1 unit/day
Amount of work done by ‘B’ = 39 × 1 = 39 units
Percentage of work done by ‘A’ = {(52 – 39)/52} × 100 = 25%
