Question

A bottle is filled with water up to a level of 3/4th. Mohan comes and fills the water bottle fully. By
4
what percent did the volume of water in the bottle increase?

Answer 1

Step-by-step explanation:

1 litre is a bottle volume (you don’t give this). The total volume of water is:

5 x 3/4 = 15/4 = 3. 75 litres.

Therefore, you will require 4 bottles. It is normal to leave a headspace of 4% of the liquid volume in a bottle. 4% of 3 bottles is 120 ml. That 120 ml can be poured into the 4th bottle to increase the water volume to 0.75 l + 0.120 l = 0.87 litres.

Therefore, 3 of the ‘full’ bottles will each contain 960 ml while the 4th will contain 870 ml, leaving a headspace of 130 ml.

Answer:

Assume 1 litre is a bottle volume (you don’t give this). The total volume of water is:

5 x 3/4 = 15/4 = 3. 75 litres.

Therefore, you will require 4 bottles. It is normal to leave a headspace of 4% of the liquid volume in a bottle. 4% of 3 bottles is 120 ml. That 120 ml can be poured into the 4th bottle to increase the water volume to 0.75 l + 0.120 l = 0.87 litres.

Therefore, 3 of the ‘full’ bottles will each contain 960 ml while the 4th will contain 870 ml, leaving a headspace of 130 ml.
