    A 800 – 80 – 16 Correct Answer Incorrect Answer
    B 1100 – 110 – 22 Correct Answer Incorrect Answer
    C 750 – 75 – 15 Correct Answer Incorrect Answer
    D 1300 – 130 – 24 Correct Answer Incorrect Answer

    Solution

    The logic here is: (1st number ÷ 10) = 2nd number & (2nd number ÷ 5) = 3rd number 800 ÷ 10 = 80 & 80 ÷ 5 = 16 1100 ÷ 10 = 110 & 110 ÷ 5 = 22 750 ÷ 10 = 75 & 75 ÷ 5 = 15 1300 ÷ 10 = 130 & 130 ÷ 5 = 26 ≠ 24 Thus, the odd number combination is 1300 – 130 – 24. Hence, the correct answer is (D).
