Question

Sandra reads 5 books, Deacon read 6 books and Breanna read 7 books. One book was read by all three children, but every other book was different. How many different books did the children read?

Answer 1

16

Explanation:

to begin with since one book is the same subtract 1 from each of the students total. this would leave you with 4, 5, and 6. Add these together and you get 15 . Then you need to add back in the one book that they all read that was the same 15+1=16
