Question
A and B can complete a task together in 10 days, while B
alone takes 20 days to finish it. A began working alone and left after ‘x’ days, after which B completed the remaining work in 15 days. Determine the percentage of the total work completed by A.Solution
Let total amount of work be 20 units
Efficiency of (A + B) = 20/10 = 2 units/day
Efficiency of ‘B’ = 20/20 = 1 unit/day
Amount of work done by ‘B’ = 15 × 1 = 15 units
Percentage of work done by ‘A’ = {(20 – 15)/20} × 100 = 25%
