Given : A can do a piece of work in 20 days and B can do it in 30 days.
To find : In how many days they together
complete the work?
We know that :
- A = 1/20
- B = 1/30
= A + B = 1/20 + 1/30
= A + B = 3 + 2/60
= A + B = 5/60
= A + B = 1/12
Therefore, 1/12 is the number of days they together complete the work.
