21.  stock is trading at S = 50. There are one-month European calls and puts on the stock
with a strike of 50. The call is trading at a price of CE = 3. Assume that the one-month
rate of interest (annualized) is 2% and that no dividends are expected on the stock over

(a) What should be the arbitrage-free price of the put?
(b) Suppose the put is trading at a price of PE = 2.70. Are there any arbitrage opportunities?
22.   A stock is trading at S = 60. There are one-month American calls and puts on the
stock with a strike of 60. The call costs 2.50 while the put costs 1.90. No dividends
