ive done it in this way:
consider the person A who has 2 speak before B be at first position.
then the rest of persons(including B) can arrange themselves in 7!
ways .similarly if A is in second position then 6! (since person B cannot come before A.when in therd position then 5!
therefore
7!+6!+5!+4!+3!+2!+1!=5913.
what do u think .am i correct????
