Question
A and B can complete a task together in 12 days, while B
alone takes 24 days to finish it. A began working alone and left after ‘x’ days, after which B completed the remaining work in 18 days. Determine the percentage of the total work completed by A.Solution
Let total amount of work be 16 units
Efficiency of (A + B) = 16/8 = 2 units/day
Efficiency of ‘B’ = 16/16 = 1 unit/day
Amount of work done by ‘B’ = 12 × 1 = 12 units
Percentage of work done by ‘A’ = {(16 – 12)/16} × 100 = 25%
