Answer 2

Time taken by the first person to do the work= 3hrs

Part of work completed by the first person in 1hr= 1/3 part

Time taken by the second person to do the work= 2hrs

Part of work completed by the second person in 1 hr= 1/2part

Part completed by first person and second person working together in 1hr= 1/3+1/2

----> 1/3+1/2

To complete the whole work they will take= 1÷5/6
