Answer 2

It will take 6 days to dig a well if they work together​.

Explanation:

Rate of work$=\dfrac{\text{Work}}{\text{Time}}$

Given : Anil will take 10 days to dig a well.

We count the whole work as 1.

Rate of work for Anil =$\dfrac{1}{10}$

Sunil will take 15 days to dig a same well.

Rate of work for Sunil = $\dfrac{1}{15}$

let t be the time they will take to dig well if they work together.

then According to the question, we have

$\dfrac{1}{t}=\dfrac{1}{10}+\dfrac{1}{15}\\\\\dfrac{1}{t}=\dfrac{3+2}{30}=\dfrac{5}{30}=\dfrac{1}{6}\\\\\Rightarrow\ t= 6$

Hence, it will take 6 days to dig a well if they work together​.
