Question

The population of a village decreased by 12%. If the original population was 25.000, find
the population after the decrease ?
​

Answer 1

Answer :-

• The population of the village after the decrease is 22000.

Given :-

• The population of a village is decreased by 12%

• The original population was 25000.

To find :-

• The population after the decrease.

Step-by-step explanation :-

• The population of a village decreased by 12% and the original population of the village was 25000. So to find the population after the decrease, we first have to find out how much is 12% of 25000! Then we can subtract it from the original population to find out the new population!

----------------------------

$\longmapsto\sf12\% \: of \: 25000$

Converting 12% into fraction,

$\longmapsto\sf \dfrac{12}{100} \times 25000$

Cutting off the zeroes,

$\longmapsto\sf\dfrac{12}{1} \times 250$

Now let's multiply the remaining numbers since we can't reduce them anymore.

$\longmapsto\sf12\times 250$

Multiplying the numbers,

$\longmapsto\overline{\boxed{\sf3000}}$

----------------------------

• 12% of 25000 is 3000. So the population of the village decreased by 3000.

• Hence, the new population is :-

• $\overline{\boxed{\tt 25000 - 3000 = 22000.}}$

Answer 2

Question :

• The population of a village decreased by 12%. If the original population was 25.000, find the population after the decrease ?

Answer :

• 22000.

Given :

• population of a village decreased by 12%.

• original population was 25000.

To find :

• population after decrease.

Solution :

• 12% of 25000

• 12/100 × 25000

• 12/1 × 250

• 12 × 250

• 3000.

So, new population is :

• 25000 – 3000 = 22000.$\: \:$
