I am not sure to be honest, but if you want a book with answers, try Discrete Mathematics with Applications by Epp [0]

It has a very large number of answers in the back, but not all of them. You'll come out ahead even if you only do the problems with an answer as each section has anywhere between 30 to 60 problems. If you want to try every problem (or some of the interesting ones that don't have answers), there's an instructor's manual for 3rd edition. The one I linked is the 4th ed. No problem as the editions 3 and 4 mainly differ in numbering of their sections and chapters, so if you match a chapter from 4 ed to the one in the instructor's manual for 3rd ed, the answers are identical and in the same order. If none of this works for you, either just google the problem or visit MSE [1] as almost none of the problems in the undergrad books are original and many people before you have asked the same questions many times over.

Note, the price of the book is steep, but I am sure you know of libg3n.
