Question

A village, having a population of 4000,

requires 150 litres of water per head per

day.

It has a tank measuring 20 m × 15 m × 6

m. For how many days will the water of

this tank last?​

Answer 1

Answer:

3 days.

Step-by-step explanation:

Volume of tank = 20 × 15 × 6 = 1800 cb. m.

= 1800 × 1000 l = 18 × 10^5 l

Per day requirement of village = 4000 × 150

= 600000 l = 6 × 10^5 l

Time = Volume of tank/Volume needed per day

$= \frac{18 \times {10}^{5} }{6 \times {10}^{5} } = \frac{18}{6} = 3$

Thus, the water is sufficient for 3 days.
