Question

Riya took out 4/5 of the water from a tank containing 45 litres of water how much water is left in the tank​

Answer 1

30 litres

Let quantity of water in tank B be x litres.

Then quantity of water in the tank A=5x litres

Total water in both the tanks =x+5x

=90 liters

⇒6x=90⇒x=15

∴ Water in tank B=15 litres

⇒ Water in tank A=15×5=75 litres

So, quantity of water to be transferred from tank A to tank B, so that each tank contains 45 litres=75−30=45 litres

Therefore, 30 liters of water should be transferred.
