A water tank has two inlet and one outlet. inlet one can fill the tank alone in 40 minutes and inlet 2 can fill the tank alone in 20 minutes. The outlet can empty the tank in 30 minutes.

Step-by-step explanation:
Inlet=20min=1/20 (A let)
outlet=40min=1/40 (B let)
hence, the work done by a&b
=a+b=1/20+(-1/40)=1/40
hence tank will get filled in 40 minutes.
