Answer 1

Given :

• A tank 3/5 full of water. 40 L more water is required to fill it up completely .

To find :

• How many litres can the tank hold ?

Solution :

$\sf A \: tank \: is \: \frac{3}{5} \: full \: of \: water .$

Let the common multiple be y .

Thus ,

3y of the tank is been filled and the capacity of the tank is 5y .

50 litres of more are required to fill the tank .

So ,

2x = 40 L

$x = \frac{40}{2}$

Now,

5x = 5 × 20

= 100 L

Capacity of tank = 5x= 5× 20 = 100 L

Hence , the tank can hold 100 L

Answer 2

Answer-

Capacity of the tank is 100L

Explanation-

The tank is already 3/5 full

Therefore 2/5 is still to be filled

We can say that

2/5 of the tank = 40L

Let the common multiple be x

2x = 40L

x = 40/2 = 20L

therefore,

5x = 5×20

= 100L
