There are non-dividend stocks with a current price of 3,000 won per share. Let's say the stock price rises to 3,500 won or falls to 2,500 won after four months. If the risk-free interest rate is 5% per annum, calculate the current appropriate price of a European put option with a maturity of 4 months and a strike price of 3,200 won using Delta Hedging and Risk-neutral valuation, respectively.
