Answer 2

Given,

Number of men = 10

Number of days = 3

To Find,

How many days one man will take to finish the job.

Solution,

Given that,

10 men can do work in 3 days.

Number of days 10men will take = 3

Let's take the number of days 1 man will take = x

Number of men = 10          1

Number of days = 3            x

We need to apply inversely proportions

Therefore, the number of days 1 man will take

x = (10 × 3)/ 1

30.

The number of days to complete work by 1 man is 30 days.
