16 men can reap the field in 30 days; Thus, 1 men in 1 day can reap the field by:
1/(16×30)
=1/480.
Now, 20 men can real the field in 1 day by:
20×1/480
=1/24.
Thus 20 men can reap the field in 24 days
1/(16×30)
=1/480.
Now, 20 men can real the field in 1 day by:
20×1/480
=1/24.
Thus 20 men can reap the field in 24 days
