A village, having a population of 4000, requires 150 litres of water per head per day. It has a tank measuring `20"m"xx15"m" xx 6"m"` . For how many days will the water of this tank last?

Explanation

Total population of a village = 4000

Water required for 4000 persons for one day = `150xx4000`=`600000`litres

Length of tank (l) = 20 m

Breadth (b) = 15 m

Height (h) = 6 m

`therefore` Volume of tank = lxxbxxh`

`1800=20xx15xx6` m^3

Capacity of water in the tank = `1800xx1000`
