28 days​

Answer 1

Answer :

240 men are needed.

$\rule{100}2$

It is given that,

• 960 men can do a work in ' 35 days '

We've to find the no. of men should join them in order to complete the task in 28 days.

Let the total no. of men needed be ' x '.

Now,

960/x = 35/28

⇒ x = 960 × 35/28

∴ x = 1200

1200 men can finish the work in 28 days.

Now,

Subtract 960 from 1200 in order to find the number of men required.

= 1200 - 960

= 240

Therefore,

240 men are needed.
