A value falls or rises from 200 to 150. By what percentage does it change (absolute value)?
Answer and explanation
Correct answer: D. 25 %
- Step 1: Change = 50. Step 2. 50 / 200 x 100 = 25 %. Answer: 25 %. Why not the others: 50 %: the absolute difference was used as the percentage. 33.3 %: the new value was used as the base. 30 % does not fit.
