Answer:
D. $375,000
Explanation:
Expected return of 13% for $1,000,000 will be $130,000
If we invest $375,000 in Stock X, our expected return based on 18% will be $ 67,500 and the remaining $625,000 will be invested in Stock X, therefore expected return based on 10% will be $ 62,500 and thereby giving the total return of $130,000 which is 13% of $1,000,000 and hence $375,000 will be invested in Stock X
