Step-by-step explanation:
If 16 men can reap a field in 30 days, in how many days will 20 men reap the same field?
From the question,
16 men can reap a field in 30 days
1 man can reap a field in =(16×30) days .. [ less men, more days]
∴ Number of men required to reap a field in 24 days =(16×30)/24
=20 men ...[ More men, less days]
Hence, 20 men required to reap a field in 24
