Question

If a tap can completely fill a tank of capacity 200 liters in 20 minutes

Answer 1

Answer:

200 divided by 20 is 10.

200 divided by 25 is 8.

So in comes 10 liters per minute, out goes 8 liters per minute, what stays is 10 - 8 = 2 liters per minute.

2 times 20 is 40.

So your answer is 40 liters.
