A rise from 200 to 230 is 30%.
A fall from 230 to 200 is about 13% when rounded to the nearest whole percent.✓Correct answer
The two directions must have equal percentage changes.
Explanation
A rise of 30 from 200 gives 30 / 200 x 100 = 15%. A fall of 30 from 230 gives 30 / 230 x 100 = 13.04%, which rounds to 13%; the two percentages differ because their old values differ.
