  1. A rise from 200 to 230 is 15%.Respuesta correcta
  2. A rise from 200 to 230 is 30%.
  3. A fall from 230 to 200 is about 13% when rounded to the nearest whole percent.Respuesta correcta
  4. The two directions must have equal percentage changes.

Explicación

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.
