Answer 2

Answer:

They will take 6 days to complete the work together .

Step-by-step explanation:

Ankit can do work in days = 10

Ankit's 1 day work = $\frac{1}{10}$

Bitoo can do work in days = 15

Bitoo 1 day work = $\frac{1}{15}$

Together they can do a part of work in 1 day = $\frac{1}{10}+\frac{1}{15}$

                                                                           = $\frac{1}{6}$

They can do  $\frac{1}{6}$ part of work in days = 1

So, They can do complete work in days = $\frac{1}{\frac{1}{6}}=6$

Hence They will take 6 days to complete the work together .
