An investor wants to generate a portfolio with an expected return of 7% p.a. and considers two investment possibilities: (i) Money market (1M-Euribor rate = 1% p.a., risk free) and (ii) stock market (expected return of the market portfolio = 10% p.a., volatility = 30 p.a.).

Task: Calculate the %-fraction (i.e. the weight) the stock market should have in this portfolio. Provide your solution in % with 2 decimal places (like, e.g., 7.12 (English TUWEL version) or 7,12 (German TUWEL version)), without %-sign.
