We will derive a two$-$state put option value in this problem. Data: $S_0=$$$240$;$x=$$$250$;$1+r=1\mathrm{.}10.$ The two possibilities for $S_T$ are $$270$ and $$170.$

Required:

B$.$ Form a portfolio of four shares of stock and five puts. What is the $($nonrandom$)$ payoff to this portfolio? $($Round your answer to $2$ decimal places.$)$

C$.$What is the present value of the portfolio?

D$.$ Given that the stock currently is selling at $$240,$ calculate the put value?
