The population of a village decreased from 1 23... - JAMB Mathematics 2023 Question
The population of a village decreased from 1,230 to 1,040 due to breakout of an epidemic. What is the percentage decrease in the population?
A
15.44%
B
15.43%
C
15.42%
D
15.45%
correct option: d
The percentage decrease in population can be calculated using the formula:
\[ \text{Percentage Decrease} = \left( \frac{\text{Decrease in Population}}{\text{Original Population}} \right) \times 100 \]
Given that the original population is 1,230 and it decreased to 1,040:
\[ \text{Decrease in Population} = \text{Original Population} - \text{Final Population} = 1,230 - 1,040 = 190 \]
\[ \text{Percentage Decrease} = \left( \frac{190}{1,230} \right) \times 100 \]
\[ \text{Percentage Decrease} \approx 15.45\% \]
