Answer 2

$\huge\mathcal{Answer:}$

Given that :

2 men can Finish the work in 10 days

● If the men will increase then working days will decrease.

◆ If two quantities are related in such a way that increase in one results decrease in other and vice-versa, then it's called Inverse Variation

This is case of inverse variation

Let's consider men be x and days be y

Here,We find a Constant k such that xy = k

Hence,

2 × 10 = x × 4

20 = 4x

x = 20/4

x = 5

5 men will finish job in 4 days
