Direct and inverse proportion.

Answer 1

Answer:

15 days

Step-by-step explanation:

So, 15 men working 1hr. a day can plough the field=16×9days

So,1 men working 1hr. a day can plough the field =16×9×15

So, 18 men working 8 hrs. a day can plough the field=16×9×15/8×18=15 days

This is an inverse proportion.
