Answer:Ram completes his work in 20 days.
He completes 1/20 th work in one day.
Shyam completes his work in 30 days.
He completes 1/30 th work in one day.
If both of them work together they can complete ( 1/20 + 1/30 ) th work in one day.
1/20 + 1/30 = 50/600 i.e. 8.3333% work completed in one day.
1 day : 8.3333% work = ? : 100% work
100/ 8.3333 = 12 days
So together, they can complete a piece of work in 12 days.

Answer:
4 whole 4/5 hours
Explanation:
Ram's one hour work = 1/8
Shyam's one hour work = 1/12
Ram and Shyam's one hour work = 1/8 + 1/12 = 5/24
Hence, Ram and Shyam would finish the work in 4 whole 4/5 hours.
