Solution



Given
We are given that:
    • your stock portfolio decreased by 25% and then increased by 20%

To find
We need to determine
    • what percent of the original value your new stock portfolio would have

Approach and Working out

Let the original value of the stock profile be 100.
    • Then, the value after 25% decrease = 100 - 25% of 100 = 75
    • And the value of a 20% increase = 75 + 20% of 75
      o 75 + 15 = 90
    • Final value = 90 and Original value = 100

Finally, suppose Final value = x% of the original value
    • 90 = x% of 100
    • x = 90


Thus, option B is the correct answer.
Correct Answer: Option B
