Question

7 men can build a wall in 4 days in how many days 2 men will build the same wall​

Answer 1

Given:

7 men can build a wall in 4 days

To find:

Number of men who can make the wall in 2 days.

Solution:

This can be solved by applying Inverse Variation.

As if the no. of worker decrease then the number of days will increase.

So,

Let the no. of men be $x$

$&#x21AA$$\bf7×4=2×x$

$&#x21AA$$\bf28=2×x$

$&#x21AA$$x=\frac{28}{2}$

$&#x21AA$$x=14$

Therefore,2 men will require 14 days to complete the same wall.
