What is the fair value for the one-year Amazon forward price?

Suppose today you buy a $1,900-strike Amazon call option for $300, sell a $2,000-strike Amazon call option for $275, sell a $1,900-strike Amazon put option for $100, and buy a $2,000-strike Amazon put option for $150. All options have an expiration date that is one year from today and the annual risk-free interest rate is zero.

What is the implicit percentage annual interest rate associated with these cash flows, assuming simple compounding?

Please round your answer to the nearest integer percentage point.
