Answer 2

Answer :

• 37 men will do it in 35 days

Given :

• If 20 men can do a piece of work in 65 days

To find :

• How Many men will do it in 35 days

Solution :

Here, Number of men doing a work and Number of days are in the inverse proportional so,

• Let the number of days taken by 35 men be x

Then,

• 65 : x = 35 : 20

⇢ 65 : x = 35 : 20

⇢ 65 × 20 = x × 35

⇢ x = 65 × 20 / 35

⇢ x = 1300/35

⇢ x = 37 men

Hence , 37 men will do it in 35 days
