Official Explanation
Because the total of the two investments and the difference between them are both known, it is possible to determine that the smaller investment (x) is $2.1 million and the larger (x + $3 million) is $5.1 million: x + x + $3 million = $7.2 million, so 2x = $4.2 million, and x = $2.1 million.
The combined return is 11.75% of the total amount, suggesting that the interest rates are among the higher choices, so begin by finding 13.5% of $5.1 million = $688,500. Subtract that from the total return of $846,000 to get $157,500. Divide $157,500 by $2.1 million to find that the second interest rate was 7.5%.
There's no mention of allocation for the Currency and Real Estate is done with equal weightage. So, why
2x comes here in the equation?
