3. Suppose the columns in the matrix in question 1 describe the allocations over four asset classes [domestic bonds (DB), foreign bonds (FB), domestic stocks (DS), foreign stocks (FS)] of four mutual funds denoted by MF1, MF2, MF3, MF4. For example, MF1 holds 10 percent of its assets in DB, 80 percent in FB, zero in DS, and 10 percent in FS. How should an investor allocate her wealth between the four funds to obtain the following asset mixes: (i) DB=0.2, FB=0.4, DS=0.2, FS=0.4 (ii) DB=0.3, FB=0.3, DS=0.2, FS=0.2 (iii) DB-1, FB=0, DS=0, FS=0 (iv) DB=0, FB=1, DS=0, FS=0 (v) DB-0, FB=0, DS-1, FS=0 (vi) DB-0, FB=0, DS=0, FS=1
