Question

A water tank has a capacity of 500 litres.If at present it is 30% full,how many more litres of water are required to make it 50% full?​

Answer 1

Answer:

Step-by-step explanation:

Tank capacity=50 litres.

Present tank capacity=30%.

So the tank has 30/100*50=15 litres.

litres of water to be filled=Already 30% filled.

Now the rest is=50%-30%.

That is =20%

so 20/100*50.

Hence the answer is =15 litres.

Answer 2

30% of 500

30/100 X 500 = 150L

so 50%of 500= 250L

so 250-150= 100L more is needed to make it 50% full
