Question
'Pawan' can complete a task alone
in 63 days. However, when working together with 'Bhanu,' they finish the same task in 42 days. How many days would it take for 'Bhanu' to complete the task alone?Solution
ATQ,
Let the total work be 126 units (LCM of 63 and 42) Efficiency of 'Pawan' = (126/63) = 2 units/day Combined efficiency of 'Pawan' and 'Bhanu' = (126/42) = 3 units/day So, efficiency of 'Bhanu' = 3 - 2 = 1 unit/day Therefore, required time = (126/1) = 126 days
