Consider a stock currently priced at $$90.$ In the next period, the stock can either increase by $40$ percent

or decrease by $25$ percent. Assume a put option with an exercise price of $$90$ and a risk$-$free rate of $6$

percent. Suppose the put option is currently trading at $$22.$ If the option is mispriced, what amount

of riskless return can be earned using a riskless hedge?
