% in T bills = 18.92%, % in P = 81.08%

Explanation:

Portfolio return = Weighted average return

Return of portfolio P = 0.14*0.6 + 0.10*0.4

Return of portfolio P = 0.124

Let % money in T bills be x

0.11 = 0.05*x + 0.124*(1-x)

0.11 = 0.05x + 0.124 - 0.124x

0.014 = 0.074x

x = 18.92%

Hence, % in T bills = 18.92%, % in P = 81.08%
