1.	A village, having a population of 4000, required 150 litres water per head per day. It has a tank which is 20 m long, 15 m broad and 6 m high. For how many days will the water of this tank last?
Answer» Given details are, Population of village = 4000 Dimensions of water tank = 20m × 15m × 6m Water required per head per day = 150 litres Total requirement of water per day = 150 × 4000 = 600000 litres Volume of water tank = l × b × h = 20 × 15 × 6 = 1800m³ = 1800000 litres We know that, Number of days water last in the tank = volume of tank / total requirement = 1800000/600000 = 3 days ∴ Water in the tank last for 3 days.

Answer»

Given details are,

Population of village = 4000

Dimensions of water tank = 20m × 15m × 6m

Water required per head per day = 150 litres

Total requirement of water per day = 150 × 4000 = 600000 litres

Volume of water tank = l × b × h

= 20 × 15 × 6

= 1800m³

= 1800000 litres

We know that,

Number of days water last in the tank = volume of tank / total requirement

= 1800000/600000

= 3 days

∴ Water in the tank last for 3 days.
