A small village having a population of 5000, requires 75 L of water per head per day . The village has got an overhead tank of measurement `40 mxx 25 mxx 15 m`.For how days will the water of this tank last?

Explanation

Given, total population of a small village = 5000
Water required per head per day `= 5000 xx 75 = 375000L`
`= (375000L)/(1000)m^(3) = 375m^(3)" "[because 1m^(3) = 1000L]`
Total capacity of water in overhead tank = Volume of overhead tank
`= 40 xx 25 xx 15 = 15000m^(3)`
`therefore` Number of days `=("Total capacity of water in over spead tank")/("Volume of water required for a small village per day")`
`= (15000)/(375) = 40` days
Hence, water of this tank will be last in 40 days.
