Assume you have a portfolio consisting of only three shares X, Y and Z with expected returns of 25.26%, 12.3% and 10.3% respectively. Your portfolio weights in this instance are 14.71% in security X and 32.2% in security Y. By finding the portfolio weight in security Z, hence find the expected return on this portfolio. Please answer as a whole number percentage to 2 decimal places. e.g. 0.1243 is 12.43
