Step-by-step explanation:
Raj takes 3 days to complete 1 work
Raj takes 1 day to complete 1/3 part of the work
Whereas,
Rohan takes 5 days to complete 1 work
Rohan takes 1 day to complete 1/5 part of the work
Total work done by both of them in 1 day = 1/3 + 1/5 part
=8/15 part
Therefore, 8/15 part of the work is done in 1 day.
The whole work will be finished in 15/8 days or 1.875 days 75 hrs.
Correct me if I'm wrong i had done these types of sums very earlier. <3
