    Doubt in question no 28
    Sir according to me
    Formula will be = (n-2) (n-1)!
    [Instead of = (n-1) (n-2)! ]
    Bcz when we do directly
    Total no of ways - no of ways when books are together
    = 11! - 10! ×2!
    = 10! (11-2)
    = 10! × 9 [.: (n-2) (n-1)! ]

    Q. 29
    Ans will be - 27
    👉 Here U took condition only when all 3 questions are correct together, then Total (64) - All correct (1) =63
    But in this 63 ways there are some ways where any 1/2 ans are right..
    👉 But we have to find ways where all ans are wrong
    So, when no ans is correct then ans will be 3*3*3 =27

    Question number - 28 -> logic was wrong in this question see another example
    Q. In how many different ways can 8 examination papers be arranged in a row, so that the best and the worst papers may never come together?
    Answer wil be-> 8! - 7!*2! = 30240
