Answer:
If 25 men working for 8 hours a day can reap a field in 20 days
The total work for reaping the field is
= 25 men × 8 hours × 20 days
= 4000 man-hour-days.
How many days will it take 18 men to reap the field if they work for 8 hours a day?
Work done by 16 men working 10 hours a day
= 16 men × 10 hours
= 160 man-hours
Number of days the work will be completed
= Total work in terms of men-hour-days / men hours available
= 4000 men-hour-days / 160 men - hours
= 25days. is the correct answer.
