Question

On an average each person in a village requires 150 litres of water per day. The village has a water tank measuring 25 m*16 m*6 m. Find the population of the village if the water in the tank is sufficient for 2 days.

Answer 1

8000 is population of village

Answer 2

Requirement of water per day by each person in a village- 150litres

Requirement of water for 2 days by each person in a village- 150*2litres = 300 litres

Volume of water tank= 25m*16m*6m= 2400$m^{3}$=2400*1000= 24,00,000litres     [1$m^{3}$=1000litres]

The population= Volume of water tank/ Requirement of water for 2 days by each person in a village= 24,00,000litres/300litres= 8000ppl Ans.
