A price rises from 80 dinars to 100 dinars. What is the percentage increase?
Answer and explanation
Correct answer: A. 25 percent
- Step 1: Increase = 100 - 80 = 20. Step 2. Percentage increase = 20 / 80 x 100 = 25. Answer: 25 percent. Why not the others: 20 percent divides by the new price; 20 dinars is not a percentage; 125 percent is the ratio of the new to the old price.
