Answer 2

Given:

We have 36 men can do a piece of work in 7 days.

To Find:

We have to find the How many men will do the same work in 42 days?

Step-by-step explanation:

        We have given the 36 men can do piece of work in 7 days

• We know it is case of inverse proportion because whenever the work and time are related to each other there is inverse relation between them
• which shows that the increase in quantity of one thin will result in the decrease in the quantity of other thing or vice- versa
• Now to complete work in 7 days no of men required is 36.
• To complete the work in 1 day the no. of men required will be given by the $36\times7$

• Thus to complete the work in 42 days we reqired the no. of men should be given by the formula

         $\frac{36\times7}{42} =6$

Hence, 6 men will be required to complete the work in 42 days.
