Rakesh & Ravi together will complete the work in 50/7 Days if Rakesh alone do in 10 Days & ravi alone in 25 days

Step-by-step explanation:

Rakesh does a piece of work in 10 days

=> Rakesh do work in 1 day = 1/10

Ravi does the same in 25 days

=> Ravi do work in 1 Day = 1/25

Rakesh & Ravi together 1 day work  = 1/10  + 1/25

=  5/50  + 2/50

= 7/50

Rakesh & Ravi together will completer the work in  1/(7/50)

= 50/7 Days
