Find the Mistake Puzzles
31. What’s wrong with this sentence: "Their is no mistakes in this sentence"?
Ans: The word "Their" should be "There", and also, it says "no mistakes" but actually contains mistakes — making it self-contradictory.
32. How many F’s are in this sentence: “Fifty five fans flew fast for fun.”
Ans: 9 F’s
Explan: Fifty (1), five (1), fans (1), flew (1), fast (1), for (1), fun (1) → Total = 7 F's at the beginning of words
Also, in “fifty” and “five”, each has 2 F’s → so total: 9 F’s.
33. What’s missing in this line: A B C D E G H ?
Ans: F is missing
Explan: It's an alphabetical sequence — A to H, but F is skipped.
34. How many squares are in a 3x3 grid ?
Ans: 14 squares
Explan:
- 1x1 squares = 9
- 2x2 squares = 4
- 3x3 square = 1
→ Total = 9 + 4 + 1 = 14

Total = 10 + 10 = 20
