The information can be translated into numbers as [1−(12+15+110)]x=25,000. Solving we get 15x=25,000 and x = 125,000, the total amount of the portfolio.

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

I don’t understand why such complicated tasks are needed because real traders will never make such complex calculations. To do this, most use trading calculators and they work very stably and can save a lot of time. I personally work on the https://www.investous.com/ platform and there is an awesome built-in calculator. So I think that there’s no point in wasting time on such calculations. By the way, what is the correct answer? I find it difficult to answer this question because I have not had practice for a long time. Do not criticize me :)
