Answer 1

Given:

• Jaya and Seema can together do a piece of work in 10 hours.Seema alone can do it in 15 hours.

To Find:

• How long will Jaya take to do it alone?

Solution:

Together work done in 1 hour = 1/10

Let one day work of jaya = x

One day work of seema = 1/15

➞ x + 1/15 = 1/10

➞ x = 1/10 - 1/15

➞ x = 3 - 2/20

➞ x = 1/30

Hence,

• Jaya alone can do work in 30 Hours.
