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?

Answer Details

To find the percentage decrease in the population, we need to calculate the difference between the initial and final population and then express it as a percentage of the initial population.
The initial population of the village was 1,230, and it decreased to 1,040 due to the breakout of an epidemic.
To find the difference, we subtract the final population from the initial population: 1,230 - 1,040 = 190
Now, we need to find the percentage decrease. We can do this by dividing the difference by the initial population and multiplying it by 100.
Percentage decrease = (difference / initial population) * 100
Substituting the values: Percentage decrease = (190 / 1,230) * 100
Simplifying the equation: Percentage decrease = 0.154472 * 100 Percentage decrease ? 15.4472
Rounding to two decimal places, the percentage decrease in the population is approximately 15.45%.
Therefore, the correct option is 15.45%.
