62This one is not very difficult i guess...
first of all note that the denominoator is 2007!(2009)
the numerator is 2007!(2008x2009-1/2007)
Now can you solve it?
the answer will be 2007 :)
24Nishant sir has almost done it
[2007!(2008.2009-1/2007)2007!(2009)]
=>[(2008.2009-1/2007)2009]
=>[2008-12007.2009]
12007.2009<1
=>2008-12007.2009<2008
=>[2008-12007.2009]=2007
