      Question

      Average of five consecutive numbers is 48. Find the sum

      of smallest and largest number.
      A 92 Correct Answer Incorrect Answer
      B 94 Correct Answer Incorrect Answer
      C 96 Correct Answer Incorrect Answer
      D 98 Correct Answer Incorrect Answer

      Solution

      Let the numbers be (a - 2), (a - 1), a, (a + 1) and (a + 2).
      So, (a - 2 + a - 1 + a + a + 1 + a + 2) ÷ 5 = 48
      Or, (5a/5) = 48
      Or, 'a' = 48
      Required sum = a - 2 + a + 2 = 2a = 2 × 48 = 96
