    C 12 Correct Answer Incorrect Answer
    D 6 Correct Answer Incorrect Answer

    Solution

    Minimum number of square tiles that man needs to buy = (Length × breadth of room) ÷ (Area of each square tiles) Length of each square tiles = HCF of (36 and 24) = 12 cm So, required number of tiles = (24 × 36) ÷ (12 × 12) = 6
