A village having a population of 4000, Requires
150 liters of water per head per day. It has
a tank measuring 20m x 15m x 6 m. for
how many days will the water of this tank
left ?
Answers
Answer:
3 days
Step-by-step explanation:
volume of water tank =(20×15×6)m^3=1800m^3
volume of water required per head per day=150 litres=150×1000cm^3
=150000cm^3
volume of water required for 4000 persons per day=(4000×150000)cm^3
converting in m^3
4000×150000÷100×100×100=600m^3
so 1800m^3 water will sufficient for
1800÷600 days =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.
