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 βxβ 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 unitsEfficiency of (A + B) = 16/8 = 2 units/dayEfficiency of βBβ = 16/16 = 1 unit/dayAmount of work done by βBβ = 12 Γ 1 = 12 unitsPercentage of work done by βAβ = {(16 β 12)/16} Γ 100 = 25%
