Answer:

(A) 35

Step-by-step explanation:

Given that the tank is 3/7 full of water

And let the full quantity of water be 1

So, the amount of water needed to be filled

= 1 - (3/7)

= 4/7

Now, given that if 20 litres more is added then the tank becomes full

And 4/7 of the tank is empty

4/7 of the whole tank = 20

The amount of water that the tank can hold

= 20×7/4

=35 litres (Ans.)
