PSAT Math Multiple-Choice Practice Question 830

Question: 830

The tables below show an investor's percentage allocation in a portfolio. The first table shows the summary of investment types in the portfolio in the year 2000. The second table shows the summary of investment types in the portfolio in the year 2020.

Use the portfolio valuations from the years given in the preceding question. If the overall portfolio is growing at a linear rate, what should the value of the portfolio be in 2030?

Correct Answer: B

Explanation:

(B) Based on the numbers in the previous question, the portfolio is increasing by $60,000 every 10 years. You add $60,000 to the 2020 value of $200,000 to get $260,000. Alternatively, you could calculate the slope of increase. However, noticing this simple pattern will save you time.
