Question

A tank can hold 50 litres of water. At present, it is only 30% full. how many litres of water will fill the tank , so that is 50% full?​

Answer 1

Answer:

10 litres

Step-by-step explanation:

50litres × 30%= 15 litres(the water that have in the tank)

50litres × 50%=25 litres(the water that question want to have in the tank)

25litres - 15 litres = 10litres(the water that you need to fill in so that it can get 50% full)
