Finals Of A Math Game
Riddle: Wendy and Maverick are participating in a mathematical game show. Their scores are tied, so whoever gets the last riddle correct wins. The riddle goes like this: I am thinking of a number. It is a five-digit whole number. It can be read the same way forwards, backwards, and upside-down. The second digit is half of the third. The last digit is the product of the first and last digits. And the sum of all five digits is 10. What number am I thinking of? Wendy says, "12,421". Maverick says, "10,801". Who is correct?
Answer: Maverick is correct. The number is 10,801. This is why: Both numbers meet most of the requirements, but 12421 does not meet the second requirement because it CANNOT be read the same way upside-down as right-side-up. Many think 10801 does not meet the third requirement, but 0 CAN be half of 8 if you cut 8 in half horizontally. This way, you will get two zeros, and 10801 DOES meet the third requirement. Since only 10801 meets all the requirements, it is the correct answer, and Maverick is right!
