In this type of questions we first get the filling in 1 minute for both pipes then we will add them to get the result, aspart filled by a in 1 min = 1/20part filled by b in 1 min = 1/30part filled by (a+b) in 1 min = 1/20 + 1/30= 1/12so both pipes can fill the tank in 12 mins. Part filled by b in 1 h = 1 6. Both the pipes are opened together but 4 minutes after the start the pipe a is turned off.

In This Type Of Questions We First Get The Filling In 1 Minute For Both Pipes Then We Will Add Them To Get The Result, As Part Filled By A In 1 Min = 1/20 Part Filled By B In 1 Min = 1/30 Part Filled By (A+B) In 1 Min = 1/20 + 1/30 =.
