Question

Salim provides water to a village, having a population of 4000 which requires 150 litres of water per head per day. He has storage tank measuring 20 m × 15 m × 6 m. For how many days will the water of his tank last? He increased the rate for providing water as the dependence of villagers increased on him. Which value is depicted by Salim?

Answer 1

Answer:

total population of village = 4000

total water required by each person per day = 150 litres

total water needed to all people for one day = 4000 × 150 = 6,00,000 litres.

capacity of the water tank = 20×15×6 = 1800 litres

the tank will last for 1800/600000 = 0.003 days

the value depicted by Salim = rate of water.

hope it helps you

Answer 2

$\huge\underline{\underline{\color{green}{\bf\pmb{Answer}}}}$

Number of days water will last = $\frac{VolumeOfTank}{TotalWaterRequiredPerDay}$

Length ⇒ 20m

Breadth ⇒ 15m

Height ⇒ 6m

Volume of Tank ⇒ L × B × H

Volume of Tank ⇒ (20 × 15 × 6) m³

Volume of Tank ⇒ 1800 m³

Water required per person per day ⇒ 150 litres

Water required for 4000 persons per day ⇒ (4000 × 150) litres

⇒ 4000 × 150 × $(\frac{1}{1000} ) m^3$

⇒ 600 m³

Number of days water will last = $\frac{VolumeOfTank}{TotalWaterRequiredPerDay}$

⇒ $\frac{1800m^3}{600m^3}$

⇒ 3

Thus the water will last for 3 days

Thank

You
