    E None of these Correct Answer Incorrect Answer

    Solution

    Alternative Method: Some Timex are Fastrack (I) → Probable conclusion → All Fastrack may be Timex (A). Hence conclusion I follows. Some Rolex are Titan (I) → Conversion → Some Titan are Rolex (I). Hence conclusion II does not follows. Some Rolex are Titan (I) → Conversion → Some Titan are Rolex (I) + Some Rolex are Fastrack (I) → Probable conclusion → Some Titan are Fastrack (I) + Some Fastrack are Timex (I) → Probable conclusion → Some Timex can be Titan (I). Hence conclusion III follows.
