[BOB(PO), 2011]

    • Explanation

    According to the question

    The average of 8 consecutive odd numbers =6568= 82

    ∴ Fourth number = 82-1=81

    First number = 75

    Average of 4 even numbers = 87

    ∴ Second even number = 87-1= 86

    Second largest even number = 88

    ∴ Required sum =75+88=163

    Hence, Option C is correct.
