Answer:

33.33%

Explanation:

Let weight of T-bill be x, therefore weight of stock will be 1-x

Portfolio = Weight of stock*Beta of stock + Weight of T-bills*Beta of T-bills

1 = (1-x)*1.5 + x*0

1 = 1.5 - 1.5x

x = 0.5/1.5

x = 0.3333

x = 33.33%

Therefore, the percentage of the portfolio invested in treasury bills is 33.33%.
