Question

4.Tank A contains 5 times as much water as
Tank B. How much water must be transfer
from Tank A to Tank B so that each tank
contains 45 litres of water?
(A) 30 litres
(B) 60 litres
(C) 75 litres
(D) 45 litres​

Answer 1

Answer:

Let quantity of water in tank B be x litres.

∴ 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 litres of water should be transferred.

hope it helps
