a village having population of 4000.requires 150 litre water per head per day .it has area measuring 20 m by 15 m by 6 m.for how many days the water of tank was empty
Answers
Answer:
3days
Step-by-step explanation:
20×15×6=1800m^3
1m^3=1000liters
1800m^3=1800000
no.of days water required by village =4000×150=600000
1800000÷600000=3
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.
