PSAT Math Multiple-Choice Question 829: Answer and Explanation

Question: 829

If the total value of the investment portfolio in 2000 was $80,000 and the total value of it in 2020 was $200,000, by approximately how much did the amount invested in bonds increase from 2000 to 2020?

• A. $8,000
• B. $14,000
• C. $20,000
• D. $28,000

Correct Answer: C

Explanation:

(C) Bonds represented 30% of the 2000 portfolio and 22% of the 2020 portfolio. You can find the increase in bonds by subtracting the 2000 bond amount from the 2020 bond amount:

(0.22 × 200,000) - (0.3 × 80,000) = 20,000
