A completes a work in 12 days and B complete the same work in 36 days. If both of them work together, then the number of days required to complete the work will be?
Answer/Solution

Steps/Work
If A can complete a work in x days and B can complete the same work in y days, then, both

Therefore, here, the required number of days = 12 × 36/ 48 = 9 days.
Option 'A'
of them together can complete the work in x y/ x+ y days
