Answer 1

There is 3 ltires of water in the bottle.
3 litres = 3000 ml
Each boy drinks 300 ml of water .
So the amount of water consumed is
=5 × 300
= 1500ml
Water left in the bottle = 3000 - 1500 = 1500ml
Percentage of water left is
= 1500/3000 × 100
= 1/2 × 100
= 50%
Therefore, there is 50% of water left in the bottle.
