## Trivia question #6:

Lizzie, Isaac, Justine and Mike each bought a different dessert. One of them bought a cupcake; one bought a doughnut; one bought a brownie; one bought ice cream. One spent \$1; one spent \$2; one spent \$3; and one spent \$4. Using the set of clues below, who bought the ice cream?

• CLUE 1: Lizzie spent more money than Justine.
• CLUE 2: Justine bought the brownie.
• CLUE 3: Of the person who spent \$1 and the person who spent \$4, one of them was Lizzie and the other one bought the doughnut.
• CLUE 4: The person who bought the cupcake, the person who bought the brownie, the person who spent \$2, and Isaac are all different people.

• We know (because of Clue 3) that Lizzie spent either \$1 or \$4. Because of Clue 1, we also know Lizzie spent more money than Justine, which means Lizzie can’t have spent \$1 (the lowest amount). So Lizzie spent \$4. Because of Clue 3, this means that the person who did spend \$1 bought the doughnut.
• Clue 2 says that Justine bought the brownie. Because of Clue 4, we then know that Justine didn’t spend \$2, since the \$2-spender and the brownie-buyer are not the same person. We also know that Isaac didn’t buy the cupcake (or the brownie) or spend \$2.
• Therefore, since we already know Lizzie spent \$4, Mike is the only one who could have spent \$2.
• Since the \$1-spender and the doughnut-buyer are the same person, this has to be Isaac—he’s now the only one who doesn’t have either dessert or money accounted for yet.
• That leaves Justine having spent \$3.
• Clue 4 says that the person who spent \$2 and the person who bought the cupcake are not the same. Since Mike spent the \$2, Lizzie must have bought the cupcake.
• This leaves us with our answer: Mike bought the ice cream!

If you figured that out, reward yourself with your dessert of choice. Oh, and you might be ready to tackle 9 of the toughest riddles ever.

## Trivia question #7:

…whose first digit is one-fourth of the last digit; the second digit is six times the first digit; and the third digit is the second digit plus three.

Since the second digit is six times the first, the second digit must be 6, because it’s the only number that is still a single digit and is divisible by six. (It couldn’t be 0 either, because the second digit is six times the first digit, which would make the first digit 0, impossible for a four-digit number.) Once you’ve figured that out, you can figure out that the first digit is 1, the last digit is 4, and the third digit is 9.

Now try the riddle that’s stumping mathematicians. Can you solve it in under 60 seconds?

## Trivia question #8:

James’s mum has four children. Their names are April, May, June, and ______?
