Question

The population of a city decreased from 25,000 to24,000 . find the percentage

decrease.​

Answer 1

25000-24000/25000×100=1000/25000×100=4%

Answer 2

Before, finding the answer. Let's find out on how we can find the answer.

• First, we have to find how much is decreased. So, to do that we have to subtract the Original Population and Current Population.
• Now, after we find that. We must use the formula of :

$\sf \dfrac{Decreased \: Population}{Original \: Population} \times 100$

• Where, we have to multiply both the decreased population and 100.
• Then, we must divide it by the Original Population.

Given :

• Original Population = 25,000
• Current Population = 24,000

To find :

• decrease percentage

Solution :

Decreased Population = Original Population - Current Population

                                      = 25,000 - 24,000

                                      = 1,000

$\sf Decrease \: Percentage= \dfrac{Decreased \: Population}{Original \: Population} \times 100$

                               $\sf = \sf \dfrac{1000}{25000} \times 100$

                               $\sf = \dfrac{100 \not0 \not0 \not0}{25 \not0 \not0 \not 0}$

                               $\sf = \dfrac{100}{25}$

                               $\sf = 4 \%$

Hence, Decrease Percent is 4%.
