Question

2. A small village, having a population of 5000,
requires 130 litres of water per head per day.
The village has got an overhead cuboidal tank
of measurement 20 m x 13 m x 10 m. For how
many days will the water of this tank last?​

Answer 1

Answer:

40 days

Step-by-step explanation:

number of people = 5000

75 litters water requires for 1 people

75 x 5000 litters water requires for 5000 people

375000 litters water requires for 5000 people

volume of water in overhead tank = 40 x 25 x 15 m³ = 40 x 25 x 15 x 1000 litters

therefore number of days = 40 x 25 x 15 x 1000/375000

                                            =  40 days
