Question
Two workers, A and B, can finish a task in 36 days and 48
days respectively, working alone. How many days will they take to complete the work together?Solution
ATQ,
Let the total work be 144 units (LCM of 36 and 48)
Efficiency of 'A' = (144 ÷ 36) = 4 units/day
Efficiency of 'B' = (144 ÷ 48) = 3 units/day
Required time = 144 ÷ (4 + 3) = (144 ÷ 7) = 20(4/7) days
