    A Only II Correct Answer Incorrect Answer
    B Only III Correct Answer Incorrect Answer
    C Only I and II Correct Answer Incorrect Answer
    D Only I and III Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let CP of New article = Z Rs. Then MP% will be = 60 - 10 = 50% Hence, Discount % will be = 70 - 50 = 20% ATQ, Z × 1.5 × 0.8 = z + 120 1.2Z - Z = 120 0.2Z = 120 Z = 600 = 10 × 60 = 10X Hence, Z = 10X Only III is correct
