If 1/2 an investment portfolio was invested in stocks, 1/5 in a mutual fund, 1/10 in bonds, and the remaining $25,000 in a savings bond, what was the total amount in the portfolio?

(A) $100,000

(B) $125,000

(C) $150,000

(D) $200,000

(E) $250,000

We can let the total investment = n and create the following equation:

(1/2)n + (1/5)n + (1/10)n + 25,000 = n

Multiplying the equation by 10, we have:

5n + 2n + n + 250,000 = 10n

250,000 = 2n

125,000 = n

Answer: B
