Answer 1

How mate!!

Let the number of fill pipes be 'n'. Therefore, there will be (8 - n) waste pipes.

Each fill pipe fills 18th of the tank in an hour. So, "n" fill pipes will fill n8th of the tank in an hour.

Each waste pipe drains 16th of the tank in a hour.

So, \"8 - n\" waste pipes will drain 8−n6th of the tank in an hour.

Keeping these 8 pipes open results in 16th of the tank being drained every hour.

Hence, n8−8−n6=−16 

Solving for n, we get n = 4. 

Therefore, there are 4 fill pipes and 4 waste pipes.
