A village having a population of 4000, requires 150 litres of water per day, It has a measuring 20m × 15m × 6m. For how many days will the water of this tank last?

$\huge\sf \green{\underline{\red{\underline{\blue{\underline{\orange{Solution :-}}}}}}}$

Volume of tank = l × b × h

➱ 20 × 15 × 6

➱ 20 × 90

➱ 1800m³

Water consumed by population per day

➱ 150 × 4,000

➱ 6,00,000m³

We know that,

★ 1 m³ = 1000 l³ ★

➱ $\frac{600\cancel0\cancel0\cancel0}{1\cancel0\cancel0\cancel0}$

➱ 600m³

Number of days $= \orange{\frac{Volume \: of \: tank}{Volume \: of \: water \: consumed \: per \: day}}$

➱ $\frac{\cancel18 \cancel0\cancel0}{\cancel6 \cancel0 \cancel0}$

➱ 3 days.
