Question

Rahul can do 2/7 of a certain work in 6 days while Suresh can do 3/5 of the same work
in 9 days. They started work together but after 7 days Rahul left the work. Find in how
many days Suresh can complete the remaining work?​

Answer 1

Answer:

Rahul

6days--------2/7 part

1days-------1/21 part

Suresh

9days--------3/5part

1days---------1/15part

In 7days

Work=(7*1/21)+(7*1/15)

=4/5

Remaining work=1-4/5=1/5

Days to complete work by Suresh =(1/5)*15=3days
