Question

    Average of three consecutive numbers is 91. Find the sum

    of smallest and largest number.
    A 178 Correct Answer Incorrect Answer
    B 180 Correct Answer Incorrect Answer
    C 182 Correct Answer Incorrect Answer
    D 184 Correct Answer Incorrect Answer

    Solution

    Let the numbers be (a - 1), a and (a + 1).
    So, (a - 1 + a + a + 1) ÷ 3 = 91
    Or, (3a/3) = 91
    Or, 'a' = 91
    Required sum = a - 1 + a + 1 = 2a = 2 × 91 = 182
