Answer:

See picture answer in spread sheet.

Also a spreadsheet explanation of how the numbers are got.

Explanation:

Payoff of a long call option = Max[S-X, 0] - P

Payoff of a short call option = P - Max[0, S-X]

Payoff of a long put option = Max[X-S, 0] - P

Payoff of a short put option = P - Max[0, X-S]

S = underlying price at expiry

X = strike price

P = premium paid or received (long options involve paying premium, and short options receive premium)
