Answer 2

Answer:

The correct answer of this question is 18 days

Step-by-step explanation:

Given - Deepa and seema together do a work in 6 days. Deepa can complete the same work alone in 9 days.

To Find - How many days will seema to complete the work alone?

Deepa and Seema together can do a work = 6 days

And they do work in one day = 1/6

Deepa alone completes the same work = 9 days

and Deepa one day of work = 1/9

Seema one day work - $\frac{1}{6} - \frac{1}{9}$

$= \frac{3-2}{18} = \frac{1}{18}$

So, Seema will complete the work alone = 18 days
