Question

A tank is 2/5 full of water,if 15 litres more is needed to fill it up,how many litres can the tank hold and how to solve it

Answer 1

Answer:

Step-by-step explanation:

A tank is 2/5 full of water.

It means that 3/5 of tank is still empty.

To fill the tank completely, 15 litres of water is needed.

So, we can say that,

To fill the 3/5 of tank, 15 litres of water is needed.

So,

3/5 × Capacity of tank = 15

Capacity of tank = 15 × 5/3

Capacity of tank = 75/3

Capacity of tank = 25.

So, tank can hold 25 litres of water.
