Try with Hints


First hint

P true gives (i) holds and (ii) do not hold that is Q true and R true

Second Hint

P true gives (i) do not hold and (ii) holds that is Q non true and R non true

Final Step

then from given conditions when P true and first condition holds that is Q true then second condition do not hold that is R is true that is if both P and Q are true then R is true.
