We will derive a two-state put option value in this problem. Data: S₀ = 240; X = 250; 1 + r = 1.1. The two possibilities for S_T are 270 and 170.

a.	The range of S is 100 while that of P is 80 across the two states. What is the hedge ratio of the put? (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.)

Hedge ratio

b-1.	Form a portfolio of 4 shares of stock and 5 puts. What is the (nonrandom) payoff to this portfolio? (Round your answer to 2 decimal places.)

b-2.	What is the present value of the portfolio? (Round your answer to 2 decimal places.)

c.	Given that the stock currently is selling at 240, calculate the put value. (Round your answer to 2 decimal places.)
