Question A5
I have 2 more than 4 and 3 less than 10. Who am I?
Answer: 2 more than 4 = 6; 3 less than 10 = 7; inconsistent. Pair? Possibly 6+7? No. The number is both? Better: Let number = X. X > 4 by 2 => X=6 AND X<10 by 3 => X=7 Impossible. This is a trick – no solution. Olympiad trick: "I have 2 more than 4" = 6, "and 3 less than 10" means 7. So the number is 6 AND 7? Wrong. Correct interpretation: The child should realize it's two separate clues for two numbers? Not likely. Let's replace: Q: "I am a number. 4 more than me is 12. 3 less than me is 5. What am I?" Answer: 8. Let's use that.
Revised A5: 4 more than me = 12; 3 less than me = 5. What number am I?
