      Question

      The average of five numbers is 62. When three more numbers

      are included, the average increases by 6. Find the average of the numbers included.
      A 78 Correct Answer Incorrect Answer
      B 80 Correct Answer Incorrect Answer
      C 82 Correct Answer Incorrect Answer
      D 84 Correct Answer Incorrect Answer

      Solution

      Sum of the 5 numbers = 62 ├Ч 5 = 310
      New average = 62 + 6 = 68
      Sum of 8 numbers = 68 ├Ч 8 = 544
      Sum of new 3 numbers = 544 - 310 = 234
      Required average = 234 ├╖ 3 = 78
