Collar

I explain collars, with examples, in my article: https://opentuition.com/articles/p4/interest-rate-collars/

Sir Thank you. Sir, Under Collar..... in case of borrowing- Buy put option and sell call option, my problem is what would be the option price for buying put and selling call? and same question in case of depositing>>>........

If you are referring to the strike price, then you can use any combination to illustrate how the collar would work (and the net premium cost) - there is no 'best' combination. If you are referring to the cost of the options, then you are given the premiums in the question.
