Question

If 225 liters of water is supplied to a family how many families can be supplied with 42075 litres of water

Answer 1

Answer: 187

Step-by-step explanation:

Method (1) (If you are not familiar with the concept of algebra, see the second method.)

Let's assume the number of families is $x$.

Litres of water supplied to a family = 225

Litres of water supplied to $x$ families = 42075

Litres of water a family gets × No. of families = Total litres of water to be (can be) supplied

225 × $x$ = 42075

∴ $x$ = 42075/225 = 187

Method (2)

One family gets 225 L of water. So 2 families will get 225 × 2 = 450 L of water. Similarly, 10 families will get 225 × 10 = 2250 L of water.

Now if we are asked how many families will get 450 L of water, our answer would be 2 (as seen above). What did we do here? We divided 450 by 225, i.e., Litres of water to be supplied/Litres of water a family gets.

Similarly, if we are asked how many families will get 2250 L, we will divide 2250 by 225.

In the question, we are asked how many families can be supplied with 42075 litres. Just divide 42075 by 225.

$\dfrac{42075}{225} = 187$

Therefore, 187 families can be supplied with 42075 litres of water.
