Hi,
please help to solve and explain- much appreciated
Security 1 - E® = 16% Standard deviation = 20%
Security 2 - E® = 12% Standard deviation = 20%
If the portfolio of the two securities has an expected return of 15%, the proportion invested in Security 1 is:
A 25%. B 50%. C 75%.

1st to 2nd will be in the ratio of (15-12) to (16-15) -> 3:1
