# How many Days will The Job be Finished :

A team can do a particular task in 10 days. Another team can do the same task in 20 days. In how many days will the job be finished, if both the teams work together?

- 15/2 days
- 19/3 days
- 20/3 days
- 22/3 days

**Answer: (3) 20/3 days**

**Explanation:-
**A team can do a particular task = 10 days

A team can do in a day = 1/10

Another team can do the same task = 20 days

Another team can do in a day = 1/20

Both teams work together in a day = 1/10 + 1/20

= (2 + 1)/20

= 3/20

Then, both teams can work together = 20/3 days

Hence, the answer is (3) 20/3 days.
