Question
X and Y can complete a task together in 24 days, while Y
alone takes 48 days to finish it. X worked alone for some days and then Y completed the rest of the work in 36 days. What percentage of the total work was completed by X?Solution
ATQ,
Let total work = 48 units
Efficiency of (X + Y) = 48 / 24 = 2 units/day
Efficiency of Y = 48 / 48 = 1 unit/day
Work done by Y = 36 × 1 = 36 units
Work done by X = 48 – 36 = 12 units
Percentage of work done by X = (12 / 48) × 100 = 25%
