Question
There were 25 workers to complete a job in 10 days. But
after 4 days, 10 workers were reassigned. How many more days will be needed now?Solution
ATQ,
Assume efficiency of each worker = 'e' units/day
Total work = 25 × 10 × e = 250e units
Work completed in 4 days = 25 × 4 × e = 100e units
Work remaining = 250e - 100e = 150e units
Remaining workers = 25 - 10 = 15
Time needed = 150e ÷ (15 × e) = 10 days
Extra days = 10 - 6 = 4 days
