Question 896341: there are 20 books of which 4 are single volume and the other are books of 8,5 and 3 volume respectively? In how many ways can all these books be arranged on a shelf so that the volume of same book are not seperated? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! You have 4 single books plus three sets. Consider the three sets as one item if you want the sets together and in order
So you have 7 items to arrange instead of 20.
If the order of the sets matter that is you can have volume 5 first then 3 then 4 then 1 then 2 then you have to deal with the sets too.
