If the cup cakes are all identical then I think the answer is 10

I think you have to think of the packets being different, maybe different colours.

There is only 1 way to put four cupcakes in each one.

But there are 5!/3! = 10 ways to put 5,3,4,4,4 cupcakes in them.

I am not certain of my logic but it sounds ok to me.
