      the rest are solo performers have to perform in a sequence. Find the number of sequences in which all three team dancers are not performing together.
      A 37800 Correct Answer Incorrect Answer
      B 36000 Correct Answer Incorrect Answer
      C 34320 Correct Answer Incorrect Answer
      D 38400 Correct Answer Incorrect Answer
      E 40320 Correct Answer Incorrect Answer

      Solution

      Total number of arrangements = 8! = 40320 ways
      If we consider 3 team dancers as one unit, number of arrangements among themselves = 3! = 6 ways
      Number of arrangements of remaining 6 performers = 6! = 720 ways
      Therefore, required number of ways = 40320 – (6 Γ— 720) = 36000 ways
