Answer:

If the pool is 2/3 filled and then the inlet pipe and drain pipe are opened, it will take 140 hours to fill the pool

Step-by-step explanation:

An inlet pipe can fill the pool in hours = 20

Inlet pipe 1 hour work = $\frac{1}{20}$

A drain pipe can empty the pool in 21 hours

Drain pipe 1 hour work = $\frac{1}{21}$

Inlet pipe and drain pipe 1 hour together work = $\frac{1}{20}-\frac{1}{21}=\frac{1}{420}$

Now we are given that the pool is 2/3 filled

So, remaining portion to be filled = $1 - \frac{2}{3} = \frac{1}{3}$

So, Inlet pipe and drain pipe fill $\frac{1}{420}$ in hours = 1

So, they can fill 1/3 in hours = $\frac{1}{\frac{1}{420}} \times \frac{1}{3} =140 hours$

Hence If the pool is 2/3 filled and then the inlet pipe and drain pipe are opened, it will take 140 hours to fill the pool
