Answer 1

Given:

• 8 men can do a work in 10 days.

To find:

• How long will 10 men take to do same work

Solution:

According to the given question,

8 men take to do a piece of work = 10 days

∴ 1 men take to do same work = 10 × 8 = 80days.

Now,

We found that 1 men can do that work in 80 days.

∴ 10 men take to do same work = $\large{\bf{\dfrac{80}{10}\: =\: 8days}}$

Hence,

10 men will take 8 days to complete same work.

Therefore,

option 'b' is correct.
