Question
Dee, Eve and Fay each have 22 tokens. They take turns: even means give that many to each of the other two; odd means receive that many from each. Dee spins 4. Eve spins 1. If they end with 15, 30 and 21, what did Fay spin?
Options
- A. 1
- B. 2
- C. 3
- D. 4
Correct answer
B. 2
Explanation
After Dee 4 (even, gives 4): Dee 14, Eve 26, Fay 26. After Eve 1 (odd, receives 1): Dee 13, Eve 28, Fay 25. We need (15, 30, 21). Fay must go from 25 to 21 (lose 4). Losing 4 means she gave 2 to each, so she spun a 2.
