      The average number of notebooks distributed among five

      students is 5. If each student received 1 notebook more than the student before him, then find the highest number of notebooks received by any student.
      A 6 Correct Answer Incorrect Answer
      B 5 Correct Answer Incorrect Answer
      C 8 Correct Answer Incorrect Answer
      D 7 Correct Answer Incorrect Answer

      Solution

      Let the notebooks received by 1st student be β€˜x’
      According to the question,
      (x + x + 1 + x + 2 + x + 3 + x + 4) = 5 Γ— 5
      Or, 5x + 10 = 25
      Or, 5x = 15
      Or, x = 3
      Therefore, highest number of notebooks received by any student = (x + 4) = 7
