      When two people of weight 66 kg and 84 kg left the group, average weight reduces by 1 kg. Find the number of people in the group now.
      A 30 Correct Answer Incorrect Answer
      B 28 Correct Answer Incorrect Answer
      C 32 Correct Answer Incorrect Answer
      D 26 Correct Answer Incorrect Answer

      Solution

      Let the number of people initially be 'n'.

      So, 60n - 59 × (n - 2) = 66 + 84

      Or, 60n - 59n + 118 = 150

      Or, n = 32

      Required number of people = 32 - 2 = 30
