Question

A pipe can fill a tank in 2 hours while another pipe fills the tank in 6 hours.If both taps are opened , what part of the tank will get filled in 1 hour?​

Answer 1

Answer:

here you go

Step-by-step explanation:

Supposed pipe A can fill the tank in 6 hours

And pipe B can empty the tank in 12 hours

So in 1 hour pipe A can fill 1/6 part of tank.

And in 1 hour pipe B can empty 1/12 part of tank

By given condition

Tank take X hours to fill completely if both pipes are open

X(1/6)-x(1/12)=1

X/6-x/12=1

2x/12-x/12=1

2x-x/12=1

X/12=1

X=12

It takes 12 hours to fill completely.
