Explanation:

To find the Beta that equals to market we need to know how much is x (weight of each stock in the portfolio) with an equation of one variable that equals to 1.

Portoflio with the same risk as the market means a beta of 1,00    

1,23 (x) + 0,84 (1-x) = 1    Stock J = 0,4103  

1,23x + 0,84 - 0,84x = 1    Stock K = 0,5897  

1,23x - 0,84x = 0,16    

0,39x = 0,16    

x = 0,16/0,39    

x = 0,4103    

The expected return of the portfolio it's defined by the weight of each stock and the expected return.

Stock J  13,25%  0,5047  6,69%

Stock K  10,60%  0,4953  5,25%

Portfolio       1,00  11,94%
