only 30 % full. How many liters of water shall I pit in
the tank, so that it is 50 % full?​

Answer 1

Answer:

10 litres

Step-by-step explanation:

Total capacity of the tank is=> 50 litres.

30% of the total capacity will be=> 50*30/100 = 15 litres.

we are required to fill it upto to 50%. So, 50% of the total capacity of the tank is=> 50*50/100 = 25 litres.

therefore, amount of water to be put in the tank to get filled its desired amount is 25-15 = 10 liters.
