Avillage , having a population of 4000 ,requires 150 litres of water per head per day .It has a tank measuring 20m ×15m×6m .For how many days will the water of this tank last ?
Answers
Answer:
3 days
Step-by-step explanation:
no. of days water will last = volume of tank/total water required per day
here l=20m , b=15m , h= 6m
volume of the tank= l× b × h
= (20 × 15× 6)
=1800 cubic m
water required per person per day=150 litres
water required for 4000 people per day=4000×
150= 600000 litre
=600 cubic m
The no. of days for which the water will last = 1800÷600 = 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.
