Question
Person 'X' can finish a task in 40 days while 'Y' can do it
in 50 days. How long will it take if both work together?Solution
ATQ,
Let the total work be 200 units (LCM of 40 and 50)
Efficiency of 'X' = 200 ÷ 40 = 5 units/day
Efficiency of 'Y' = 200 ÷ 50 = 4 units/day
Required time = 200 ÷ (5 + 4) = 22.22 days
