Easy Math Puzzles

Counting and Geometry

1. Three ants are positioned on separate corners of a triangle. If each ant moves along an edge toward a randomly chosen corner, what is the chance that none of the ants collide?
25% (All ants must move clockwise or counterclockwise; 2 safe ways out of 8 possible moves: 2/8 = 1/4.)
2. How can you measure the diagonal of a brick without using any formula, if you have three bricks and a ruler?
Stack two bricks vertically, place the third beside the bottom one, and measure the empty diagonal space with the ruler.
3. You start with a round tortilla. Divide it into eight equal pieces using only straight cuts. What’s the minimum number of cuts needed?
1 (Fold the tortilla in half three times and make one cut through all layers.)
4. Alice and Bob each make 3 straight cuts on a pie. How many pieces can they make at most?
7 (Each cut intersects all previous cuts: 1 cut = 2, 2 cuts = 4, 3 cuts = 7 pieces.)
5. You have 24 ounces of ball bearings and a balance with no weights. How can you measure exactly 9 ounces?
Divide into 12, then 6, then 3 ounces using the balance, and combine 6 + 3 = 9 ounces.
6. You have a gold bar marked into 7 equal pieces and can make 2 cuts. Pay an employee 1 piece per day for 7 days. How?
Cut into 1, 2, and 4 pieces; trade daily to give 1 piece each day. (e.g., Day 1: give 1; Day 2: trade 2 for 1, etc.)
7. Alice and Bob have 3 tasks (copying, auditing, faxing), each taking 40 minutes, with one person per task at a time. How quickly can they finish?
60 minutes (Split tasks into 20-minute intervals: e.g., Alice audits 0-40, Bob faxes 0-20, copies 20-60.)
8. Measure 9 minutes for a science experiment using a 4-minute and 7-minute hourglass.
Start both; flip 4 at 4; flip 7 at 7; flip 7 again at 8; stop at 9.

Probability

9. You have an unfair coin. How can you make a fair coin toss using it?
Toss twice; HT = heads, TH = tails, repeat if HH or TT. (Equal chances for HT and TH.)
10. An iPhone passcode is 4 digits (0-9). What’s the probability of guessing it correctly in one try?
1/10,000 (10 choices per digit, 10^4 = 10,000 possibilities.)
11. A lady claims she can tell if tea or milk was poured first. She identifies 4 out of 4 cups correctly. What’s the chance if guessing randomly?
1/16 (2 choices per cup, 2^4 = 16 outcomes, 1 correct.)
12. A committee of 3 votes; each has a 2/3 chance of approving. What’s the chance the decision passes (majority yes)?
19/27 (Binomial: 3 yes = (2/3)^3, 2 yes = 3*(2/3)^2*(1/3), total = 19/27.)
13. Roll two dice. What’s the probability the sum is 7?
1/6 (6/36 outcomes: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1).)
14. How often does it rain if the chance is 1/3 each day, over 3 days?
1 day on average (Expected value: 3 * 1/3 = 1.)
15. In ping pong, you win with probability 1/2 each rally. What’s the chance you win in 2 rallies?
1/4 (Win both: (1/2)^2 = 1/4.)

Strategy and Game Theory

16. In a bar coaster game, place numbers 1-5 on 5 coasters so no two adjacent numbers differ by 1. How many ways?
8 (Sequences like 1-3-5-2-4 or 2-4-1-3-5; total permutations adjusted for constraint.)
17. Bob is trapped in a room with 2 doors: one safe, one deadly. Two guards (one always lies, one always truths) say, “The other says this door is safe.” Which door is safe?
The door neither points to (Contradiction ensures it’s safe.)
18. In chess, you have a king and rook vs. a king. Can you force a win?
Yes (Use rook to limit king’s movement, force checkmate.)
19. In math dodgeball, hit a target numbered 1-10. What’s the expected score?

20 turns (Double 10 times from 1,000: 1K to 1M.)

50 (Middle maximizes chance of being closest.)

Medium Math Puzzles

Counting and Geometry

4. Toss a 1-inch coin onto a grid of 1.5-inch squares. What’s the chance it lands inside one square?

The robot will either return to you safely (indicating a trap) or not return (indicating the correct door). How can you ensure that you find the door to freedom?

5. The Two-Guard Door Puzzle

9. The Light Switch Puzzle
 You are outside a room with three light switches. Inside the room, there are three light bulbs. Each switch controls one bulb, and you cannot see the bulbs from outside. How can you determine which switch controls which bulb if you can enter the room only once?

10. The Knight and Knave Puzzle
 On an island, there are knights (who always tell the truth) and knaves (who always lie). You meet two inhabitants: A and B. A says, “At least one of us is a knave.” What are A and B?

– First digit (1) is one-third of the second digit (3).
– Third digit (4) is the sum of the first and second digits (1+3).
– Fourth digit (6) is three times the second digit (3).

4. The Five-Door Logic Puzzle
Solution: Test one door at a time. If the robot returns, it’s a trap. If the robot does not return, that’s the door to freedom. Repeat for the remaining doors until you find the door to freedom.

5. The Two-Guard Door Puzzle
Solution:Ask either guard, “If I were to ask the other guard which door leads to freedom, what would they say?” Then choose the opposite door.

6. The 12 Coin Problem
Solution:
1. Divide the 12 coins into three groups of 4 coins each.
2. Weigh group 1 against group 2.
3. If balanced, the odd coin is in group 3. If not, the odd coin is in the heavier or lighter group.
4. Take the heavier/lighter group and divide into two groups of 2 coins each.
5. Weigh one group against the other.
6. The heavier/lighter group contains the odd coin.
7. Weigh one coin from the remaining group against another coin.
8. The heavier/lighter coin is the odd coin.

2. Person 1 returns with the torch. (1 min, Total: 3 min)
3. Person 3 and Person 4 cross the bridge. (10 min, Total: 13 min)
4. Person 2 returns with the torch. (2 min, Total: 15 min)
5. Finally, Person 1 and Person 2 cross the bridge again. (2 min, Total: 17 min)

8. The Five Hats Puzzle
Solution:
1. The last person (5th) will count the number of red hats they see.
2. If they see an even number of red hats, they say “red” if they themselves have a red hat.
3. If they see an odd number of red hats, they say “blue”.
4. Each subsequent person uses the previous answers to deduce their hat color.

9. The Light Switch Puzzle
Solution:
1. Turn on the first switch and leave it on for a few minutes.
2. Turn off the first switch and turn on the second switch.
3. Enter the room.
4. The bulb that is on is controlled by the second switch.
5. The bulb that is off but warm is controlled by the first switch.
6. The bulb that is off and cold is controlled by the third switch.

10. The Knight and Knave Puzzle
Solution:
If A says, “At least one of us is a knave,” A must be telling the truth, making A a knight and B a knave. If A were a knave, then the statement would be false, which contradicts the scenario of having at least one knave. Thus, A is a knight and B is a knave.

I hope these solutions help clarify the puzzles!
