Answer:
Price of Put = $ 7.1037
Step-by-step explanation:
Put-Call Parity:
Price of Call + Exercise Price / (1 + Risk-free rate)^T = Price of Put + Stock Price
Price of Call = $12.30
Exercise Price = $22.50
Stock Price = $27.27
Risk-free rate = 3.9%
Time period = 6 months or 0.5 year
Now insert the values:
Price of Call + Exercise Price / (1 + Risk-free rate)^T = Price of Put + Stock price
12.30 + 22.50 / (1 + 3.9%)^0.5 = Price of Put + 27.27
12.30 + 22.50 / 1.019313 - 27.27 = Price of Put
Price of Put = 12.30 + 22.0737 - 27.27
Price of Put = $ 7.1037
