    2. Best Answer

      Number of observations = 10
      10 is an even number. Therefore, the modian = Mean of 5th[(n/2)th] term and 6th[(n/2 + 1)th] term.
      Hence,
      Median = 1/2(5th observation + 6th observation)
      ⇒ 63 = 1/2 [(x) + (x + 2)]
      ⇒ 63 = 1/2 [2x + 2]
      ⇒ 63 = x + 1
      ⇒ x = 62
      Hence, the valueof x is 62.
