Answer: C
Second problem:
Both have lost equal amount of weight. But since Carl was 8 pounds heavier than Linda, he lost less percentage of weight than her. This is because the denominator is higher on Carl’s side.
Suppose Linda was 100 pounds and Carl was 108 pounds:
Percentage weight loss for Linda = 15/100 * 100 = 15%
Percentage weight loss for Carl = 15/108 * 100 which is 13.89% approx.
