A Village, having population of 4000,requires 150 litres of water per head per day. It's has a tank measuring 20m×15×m×6m.For how many days will the water of this tank last
Answers
Answer: 3 days
Step-by-step explanation: volume of tank = lbh
= 20 × 15 × 6
= 1800 m³
1m³ = 1000 litres
So, 1800m³ = 1800000 litres
Water consumed by 1 person in 1 day = 150 litres
So, 4000 people need = 6000000 litres in one day
So 1800000 litres will last for 3 days

Answer: 3 days
Step by step explanation:
Given,
Quantity of water in tank = (20 ×15×6) = 1800m³
Population of village = 4000
Water required = 150/per head per day
Quantity of water required by the village per day:
= ( 4000 × 150) liters
= 4000×150 ÷ 1000 m³
= 600 m³
No. of days which the water will last
= 1800÷600
= 3 days
Explanation:
This question can be solved by 2 methods, I have solved this question in very simple way. In this question, There was the Given population and water requires per day.
And, There were a tank, which was wearing of 20 meters, 15 meters and 6 meters. We First find, Quantity of water in tank = (20 ×15×6) = 1800m³.
Then, We find Quantity of water required by the village per day.
= ( 4000 × 150) liters
= 4000×150 ÷ 1000 m³
= 600 m³.
And, Finally we divide it with 600 with 1800. And, we get 3 days.
