Question

the population of a city decreased from 25000 to 24500 find the percentage decrease

Answer 1

HELLO THERE☺

FIRST TAKE OUT THE DIFFERENCE BETWEEN 25000 AND 24500
25000-24500=500

SO 500 TOTAL POPULATION DECREASED IS 500

PERCENTAGE =
$\frac{500}{25000} \times 100 = 2$
THE DECREASED PERCENTAGE IS 2%

HOPE IT HELPS ^_^

Answer 2

Given :-

Original Population = 25000
New Population = 24500

Decreases in Population = 500

$Percentage Decreased \\ = \frac{decrease \: in \: population}{original \: population} \times 100 \\ = \frac{500}{25000} \times 100 \\ \\ = 2\%$

Hence the decrease in population is 2%
