20 men can cut 30 trees in 4 hours. if 4 men leave then how many trees will be cut in 6 hours

Answer»

As in 4 hours , 20 men can cut 30 trees.

So, in 1 HOUR , 20 men can cut 30 trees / 4.

So, in 6 hours, 20 men can cut 30 * 6 trees / 4 = 45 trees.

If 4 men left the WORK so rest people  = 20 - 4 = 16.

Now, 20 men can cut 45 trees in 6 hours.

So, 1 man can cut 45 trees / 20 in 6 hours.

And ,16 men can cut 45 * 16 trees / 20 =  36 trees in 6 hours .

The ANSWER will be 36.
