Answer:

20/3

Step-by-step explanation:

A can do a job in 10 days

Therefore, in 1 day, A can do 1/10th of the job.

B can do a job in 20 days.

Therefore, in 1 day, A can do 1/20th of the job.

Therefore, A & B together can do (1/10 +1/20)=  3/20th of the job.

A & B together can do 3/20th of a job in 1 day.

Hence, A & B together can do the complete job in 20/3 days.
