Question

The capacity of an overhead water tank is 3000 liters. There are 16 families living in this building. If each family uses 225 liters every day, will the tank filled to capacity be enough for all the families? If not, what will the daily shortfall be?

Answer 1

Hint: Compare the capacity of an overhead water tank and the 16 families living in the building, where each family uses 225 litres. If any difference then there is a shortfall of the water.

Complete step-by-step answer:
For checking if the capacity is enough or not we will calculate total usage by all 16 families and deduct it from the total capacity of the water tank. We can use these methods to calculate basic practical problems like how big a water tank one should buy for their colony or for their personal use.
Given in the question, Capacity of an overhead water tank is a total 3000 liters.
There are 16 families living in the building, where each family uses 225 liters.
Capacity of water used by 16 families, each family using 225 liters is
\[ \Rightarrow 225 \times 16\]
Capacity of water used by 16 families \[ \Rightarrow 3600litres\]
So, the shortfall of water is = Capacity of water 16 families needed – Capacity of water tank.
Shortfall of water = 3600 – 3000.
 \[ \Rightarrow 3600 - 3000\]
\[ \Rightarrow 600Liters\]
The capacity of the water tank is not enough for 16 families, as there is a shortfall of total 600 liters.
So, they need to add 600 liters of water tank to fill up basic needs of all the 16 families.

Note: The difference in the water consumed by the families and the capacity of the water tank will fetch the shortfall of water. So, we need to measure the water consumed by each family and then multiply it by the total no. of families to calculate exact water consumption.
