Answer:
5 days
Explanation:
Instead of working with a number of men and the number of hours in a day, consider the number of 'man-hours' used.
5 men working for 6 hours a day means:
5×6=30 man-hours a day.
The entire task of reaping the field takes:
30×20=600 man-hours
The question involves inverse proportion because if there are more men working and they work for more hours each day, then the task will be completed in fewer days.
15 men working for 8 hours a day means:
15×8=120 man-hours per day
To complete the task which requires 600 man-hours:
600÷120=5 days

Answer:
5 days
Step-by-step explanation:
5 men working 6 hours is 5 x 6 = 30 and the entire task of reaping the field is 30 x 20 = 600, so 15 men working 8 hours is 15 x 8 = 120, then divide 600 by 120 which is 5
