Riddles!! – Food for thought

I read an article titled “Problem solving is an essential hacker skill” at https://null-byte.wonderhowto.com/forum/problem-solving-is-essential-hacker-skill-0150882/. The article says that problem solving, along with persistence and creativity, is an essential skill in this profession. So, I am posting some riddles as food for thought for our brains. I will post the answers after couple of days.
