Can you solve this tricky problem?
A short and seemingly easy math riddle has been circulating online, prompting readers to slow down and think carefully before answering. Although the question looks straightforward, it relies on understanding how books are physically structured rather than simple counting.
The Puzzle Explained
The riddle states:
- A child tore out pages 7, 8, 100, 101, 222, and 223 from a book.
- The question asks: How many pages were actually torn out?
At first glance, many people assume the answer is simply the number of page numbers listed. However, this is where the trick lies.
Key Detail Many People Miss
- Books are printed with two pages on one sheet of paper
- Each sheet contains:
- An odd-numbered page on the front
- The next even-numbered page on the back
This means tearing out one physical sheet removes two page numbers at once.
Breaking It Down Step by Step
- Pages 7 and 8 are on the same sheet → 1 torn page
- Pages 100 and 101 are on the same sheet → 1 torn page
- Pages 222 and 223 are on the same sheet → 1 torn page
Final Answer
- Total physical pages torn out: 3
Correct Choice
- B: 3
Why This Puzzle Is Interesting
- It tests logical reasoning, not math skills alone
- It encourages thinking about real-world objects, not just numbers
- It highlights how assumptions can lead to incorrect answers
