Answer: after joining of Ram, work will be finished in 4.44 days

Step-by-step explanation:

In 1 day, Rajesh can do =1/25 of work

And in 1 day Ram cam do = 1/20 of work

In 10 days Rajesh did = 10×(1/25) = 2/5 of work

Remaining work is 1- 2/5 = 3/5

Now in 1 day Rajesh and Ram can do together = 1/25+1/20 = 9/100 of work

They'll finish the work in = (2/5) /(9/100) = 4.44 days
