Correct Answer: Option D
Explanation

Original population = 1,230
New population = 1,040
Decrease in population = 1,230 – 1,040 = 190
Percentage decrease in population = decrease in population   x 100%
                                                              original population         

= \(\frac {190}{1,230}\) x 100 = 15.45%

There is an explanation video available below.
