Question
4000 members require 150 litres of water per head per day and the tank dimensions are 20m x 15m x 6m, how many days will the water of this tank last ?
- 2
- 3
- 4
- 5
Hint:
Volume of cuboid = l x b x h
Where l is length , b is breadth , h is height
1 litre = 0.001 m3
The correct answer is: 3
We have given that
Number of members = 4000
Water used per head per day = 150 litres
Tank dimensions
Length = 20 m
Breadth = 15 m
Height = 6 m
Therefore, volume of tank = l x b x h
= 20 x 15 x 6
= 1800 m3
We know that 1 litre = 0.001 m3
Water used per head per day = 150 litre = 150 x 0.001
= 0.150 m3
Water required for 4000 members = 4000 x 0.150
= 600 m3
Therefore the water will last for days = Volume of tank / water required per day
= 1800 / 600
= 3
Therefore, the correct option is b) 3.
We know that 1 litre = 0.001 m3
Water used per head per day = 150 litre = 150 x 0.001
Water required for 4000 members = 4000 x 0.150
Therefore the water will last for days = Volume of tank / water required per day
Therefore, the correct option is b) 3.
