D) 2

Answer 1

Hey.

Here is the answer.


Water required per head = 150 L

Total no. of teenagers = 5000


So, total required water = 150 × 5000


= 750000 L


Dimensions of the tank installed

20m × 15 m × 5 m


So, volume of the tank


= 20 × 15 × 5 = 1500 m^3


As , 1 m^3 = 1000 L


So, 1500 m^3 = 1000×1500


= 1500000 L


Hence, capacity of the tank is 1500000 L.


So, no. of days for it will be sufficient


= capacity / daily requirements


= 1500000/ 750000


= 2


So, The water of this tank will sufficient for 2 days.


Answer : (D)
