उत्तर
A family gets three buckets of water per person per day.
Explanation:
The United Nations has recommended that a minimum of 50 litres of water should be available to each of us per person per day for drinking, washing, cooking and cleaning. This amount is about two and a half buckets of water per person per day. Therefore, a family getting three buckets of water per person per day does not show a water shortage.
