Puzzle questions are problems or riddles that are designed to be solved through logical thinking and problem-solving skills. They can be in the form of verbal or math problems, and often involve finding patterns, identifying relationships, and making deductions. Puzzle questions can be challenging and require persistence and creativity to solve. They are often used in educational settings to help students develop critical thinking and problem-solving skills, and are also used in job interviews to assess candidates’ ability to think analytically and solve problems.
