Combinatory

Arjun Suresh I’m including here some of difficult question I encountered & Could not solve !

In combinatorics 2-3 Things I think are important

1. How to solve this questions carefully ? ( I think this is most difficult topic ) Specially How to go step by step without making mistake, I tend to do too many mistake if I try big bang approach !

2. Will questions like this difficulty come in GATE ?

I’m mostly good in COmbinatorics.
