1. Total capacity = 450 litres
Amount of water that decreases every hour = 9 litres
Amount of water that decreases after 10 hours = 9 × 10 = 90 litres
Therefore, amount of water after 10 hours = 450 litres - 90 litres = 360 litres
2. The precautions we must take to save water =
* Switch off taps when not in use
* Fix holes or leaks immediately.
* Use innovative methods like rainwater harvesting
