The amount of water required by the village 4000×150=600000litres

The volume of the tank =20×15×6=1800m3

Convert into litres. =1L=0.001m3

1800/0.001=1800000m3

The number of days =1800000/600000=3

The water lasts 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.
