hey bro its quite simple...
23!= 1.2.3.4.5.6.....21.22.23
now multiply both numerator n denom by 24
which wil give 23!= 24!/4!
similarly other egs....the catch was to find those numbers which are factorial results...

hey guys ...i think answer should b 720...
explanation...
5 diff balls distributed to 3 diff ppl...each gettin atleast 1...
suppose 5 balls are identical...
now these balls can be distributed in 5-1C2 ways....tht is 6 ways...
but the balls are diff so we wil multiply it with 5!......

i wil also go for option D
explanation by some egs.....5!=6!/3! 23!=24!/4! 119!=120/5! 719!=720!/6!
since all other options are contradictin the above egs. so the option 4 is corect
