5 Fun Math Puzzles to Challenge Your Brain - Can You Solve Them?

1. 6-Eleven

Riddle: I add six to eleven and get five. How does that make sense?

Answer: Time to think outside the box! (Here’s a clue: Look at a clock.) If it’s 11 a.m. and you add six hours, you land on 5 p.m. Not so crazy now, huh?

2. The Most Frequent Digit

Riddle: Which single digit appears the most between 1 and 1,000? Hint: Patterns, patterns, patterns!

Answer: It’s 1! Every digit (0–9) appears equally often in groups of ten, but since we’re counting all the way to 1,000, the number 1 sneaks in one extra time. Total count? 301 times for 1, while the others show up 300 times.

3. The Magical Math Trio

Riddle: 2 + 2 = 2 × 2. That’s cool. But can you find three different whole numbers whose sum equals their product?

Answer: Meet the magic trio: 1, 2, and 3. Their sum? 1 + 2 + 3 = 6. Their product? 1 × 2 × 3 = 6. Math is wild!

4. The Egg Laying Conundrum

Riddle: If 1.5 hens lay 1.5 eggs in 1.5 days, how many eggs will 6 hens lay in 6 days?

Answer: Two dozen! Scaling up both the number of hens and the time by a factor of 4 means the egg count multiplies by 16. That’s 1.5 × 16 = 24 eggs. Speaking of eggs, here’s another head-scratcher...

5. Last Cliffhanger: Two Boys Tuesday

This one’s a real brain teaser! Imagine you meet a man who tells you he has two children, and at least one of them is a boy. Then, casually, he drops another clue: One of them was born on a Tuesday. Now, here’s the puzzle: What are the chances that both children are boys? At first glance, it might seem like an unnecessary detail - why does Tuesday even matter? But hidden inside this simple statement is a fascinating probability twist that has stumped many sharp minds. We’ll reveal the answer in our next blog!
