- Statement 2. There are exactly two wrong statements in this list.
- Statement 3. There are exactly three wrong statements in this list.
How many wrong statements are in the list above?
Riddle from: Brilliant
Solution
There are two wrong statements in the list above. The third statement contradicts itself, making it a wrong statement. First statement says that there is exactly one wrong statement in the list, meaning the other two must be correct statements. But since all the statements say “exactly”, only one of these statements can be correct, thus making statement two correct.
