Question

A bottle was filled with 3 L of water.
Each of 5 boys drank 300 mL of water
from it. What per cent of the bottle is still full? ​

Answer 1

Answer:

There is still 50% of water in the bottle.

Answer 2

Answer:

3L = 3000 ml

water consumed by each boy = 300 ml

Water consumed by 5 boys = 300 X 5

= 1500 ml

water left in bottle = 3000 ml - 1500 ml

= 1500 ml

percentage of water left in bottle = 1500/3000 X 100

= 50%
