Answer 2

Answer:-

20 men can reap the field in 21 days.

Calculation :-

The number of men doing a work and the number of days taken are in inverse proportion.

Let the number of days taken by 20 men to reap the field be a.

Then, 30:20 :: 1/ a:14

Applying the rule, product of extremes = product of means

=30×14=20×a

$= > a = \frac{30 \times 14}{20}$

=> a =21

Hence, 20 men can reap the field in 21 days.
