$$(\frac{1}{2} + \frac{1}{5} + \frac{1}{10}) = \frac{8}{10}$$ of the portfolio is held in stocks, a mutual fund, and bonds.

The remaining $25000, held in a savings bond, equals $$(1 -\frac{8}{10}) = \frac{2}{10} = \frac{1}{5}$$ of the total amount. Total amount in the portfolio$25,000 = $$\frac{1}{5}$$ total
$25,000 * 5 =$125,000

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

This was a simple question, the exact question I fear on the GMAT. Tough questions, I seem to do a lot better on. I really am just trying to work on the mechanics of taking clear notes, not skipping steps or making simple errors.

I immediately converted the fractions to have common denominators of 10.

Stocks = 5/10,
mutual funds = 2/10
bonds = 1/10
savings bond = 25,000

-If I sum the fractions, I get 8/10 or 4/5.
-That means the savings bond is 1/5 of the entire portfolio.
