Question

Vivek arranged 1,105 books in 13 bookcases so that each case has the same
number of books. How many books did Vivek put in each bookcase?
(Hint: Divide 1,105 by 13)​

Answer 1

Answer:

why are you asking us the answer then you know that we have to divide 1,105 by 3

Answer 2

Answer:

25P25 for the first place, as order matters and there's 25 ways the books could be arranged on that shelf, or it could be in the second place, third, etc. so (25P25)∗10?

Or would I do it like a Stars and Bars question? Because the above answer is massive.

b) Order doesn't matter, so combinations now. Would I do 25C25∗10? Or is there a way to differentiate Stars and Bars between permutations and combinations?

c) Stars and Bars but with the restriction of each gap having one at least?
