Collection of Easy Math Riddles
Here is a selection of easy math riddles along with their answers. Each riddle is designed to be solvable with basic arithmetic or logical reasoning.
Riddle 1: The Mysterious Number
Riddle: I am a three-digit number. My tens digit is five more than my ones digit, and my hundreds digit is eight less than my tens digit. What number am I?
Answer: 194
Explanation: Let the ones digit be \( x \). Then the tens digit is \( x + 5 \) and the hundreds digit is \( (x + 5) - 8 = x - 3 \).
Setting up the equation:
- Hundreds: \( x - 3 \)
- Tens: \( x + 5 \)
- Ones: \( x \)
Thus, the number is 194.
Riddle 2: The Age Puzzle
Riddle: Anna is twice as old as Bob. If Bob is 10 years old, how old will Anna be in 5 years?
Answer: Anna will be 25 years old.
Explanation: If Bob is 10 years old, then Anna is \( 10 \times 2 = 20 \) years old. In 5 years, Anna will be \( 20 + 5 = 25 \) years old.
Riddle 3: The Apples and Oranges
Riddle: If you have 3 apples and you take away 2, how many apples do you have?
Answer: You have 2 apples.
Explanation: The riddle plays on the wording. You took away 2 apples, so those are the apples you have now.
Riddle 4: The Train Dilemma
Riddle: A train leaves the station traveling at 60 miles per hour. Another train leaves the same station 30 minutes later traveling at 90 miles per hour. How far from the station will they meet?
Answer: 90 miles.
Explanation: The first train travels for 0.5 hours (30 minutes) at 60 mph, covering \( 60 \times 0.5 = 30 \) miles. The second train’s speed is 90 mph, and the time taken to catch up is \( 30/(90 - 60) = 1 \) hour. During that hour, the second train travels \( 90 \times 1 = 90 \) miles from the station.
Riddle 5: The Number Sequence
Riddle: What is the next number in the sequence: 2, 4, 8, 16, ...?
Answer: 32
Explanation: Each number is multiplied by 2 to get the next number in the sequence.

Riddle 6: The Missing Digit
Riddle: I am a two-digit number. When you reverse my digits, I become 27 less than I was. What number am I?
Answer: 72
Explanation: Let the two-digit number be \( 10a + b \). When reversed, it becomes \( 10b + a \). The equation is:
\[ 10b + a = 10a + b - 27 \]
Solving this gives \( 9b - 9a = -27 \) or \( b - a = -3 \). Hence, \( b = a - 3 \). The only two-digit number satisfying the conditions is 72.
Riddle 7: The Coin Riddle
Riddle: You have a coin that is worth 25 cents. You have two coins, but one of them isn’t a quarter. What are the two coins?
Answer: A quarter and a penny.
Explanation: The riddle states that only one of them isn’t a quarter, which means the other is.
