A village having a population of 5000 requires 250 litres of water per head per day. It has a tank measuring 50 m × 40 m × 25 m. The water of this tank will last for?
Daily need of water = 5000 × 250 Amount of water in the tank = 50m × 40 m × 25 m Number of days = amount of water in the tank/ daily need of water Number of days = (50 × 40 × 25 × 1000) /(5000 × 250) (1000litre = 1m³) Number of days = 40 days
