To have a well-balanced portfolio, the investor imposes the following conditions. At least one-half of the total portfolios is to be allocated to type A investments and at least one-fourth of the portfolio is to be allocated to type B investments. What is the optimal amount that should be invested in each type of investment? What is the optimal return?
