Question
Meg, Ned and Ola each have 18 tokens. They take turns drawing a card showing 1, 2 or 3. Even number: give that many to each of the other two. Odd: receive that many from each. Meg draws 3. Ned draws 2. If they end with 25, 10 and 19 respectively (Meg, Ned, Ola), what did Ola draw?
Options
- A. 1
- B. 2
- C. 3
- D. Cannot tell
Correct answer
A. 1
Explanation
After Meg (3): M receives 3 from each → M 24, N 15, O 15. After Ned (2): N gives 2 to each → M 26, N 11, O 17. To reach (25, 10, 19), Ola must receive 1 from Meg and 1 from Ned. This happens when Ola draws 1 (an odd number). M 26-1=25, N 11-1=10, O 17+2=19. So Ola drew 1.
