At first glance, this riddle looks like a simple illustration. A cat, a turtle, and a table—nothing too complicated, right? But hidden within this playful image is a math puzzle that has sparked debate and confusion all over the internet.
The question is simple: What is the height of the table?
You’re given two visual clues:
- In the first image, the cat is on the table and the turtle is on the floor. The total height from the turtle to the cat is 170 cm.
- In the second image, the turtle is on the table and the cat is on the floor. The total height is now 130 cm.
Now it’s your turn: Based on these clues, can you calculate how tall the table actually is?
Common Mistakes People Make
Before we break down the solution, let’s talk about why this puzzle throws so many people off.
- Overlooking the Details: Many people treat the images as decorative rather than part of the equation. But every position matters. Whether the animal is on the table or on the ground makes a big difference.
- Not Defining Variables: A lot of people try to guess the height by estimating or using visual proportions. But like any math problem, this one needs clear variables and logical steps.
- Assuming It’s a Trick Question: This puzzle might seem like it has a hidden twist, but the answer is right there if you approach it logically.
Now let’s walk through how to solve this step by step.
Step-by-Step Guide to Solving the Puzzle
Step 1: Define Variables
To solve this riddle, let’s give names to the unknowns:
- Let T be the height of the table.
- Let C be the height of the cat.
- Let R (for “reptile”) be the height of the turtle.
Now let’s use the two scenes as equations.
Scene 1: Cat on the table, turtle on the ground.
The total height from the turtle on the floor to the cat on the table is: T + C = 170 cm (Equation 1)
Scene 2: Turtle on the table, cat on the ground.
This time, the total height from the cat on the floor to the turtle on the table is: T + R = 130 cm (Equation 2)

Now we have:
- T + C = 170
- T + R = 130
Step 2: Subtract the Equations
To find the difference between the cat and the turtle’s height, subtract Equation 2 from Equation 1:
(T + C) – (T + R) = 170 – 130
T + C – T – R = 40
C – R = 40 cm (Equation 3)
This tells us that the cat is 40 cm taller than the turtle.
Step 3: Add Equations to Eliminate C and R
Now let’s add Equation 1 and Equation 2:
(T + C) + (T + R) = 170 + 130
2T + C + R = 300
But from Equation 3, we know that C = R + 40.
Substitute that into the combined equation:
2T + (R + 40) + R = 300
2T + 2R + 40 = 300
2T + 2R = 260
T + R = 130
And wait—T + R = 130 is Equation 2 again! That means everything checks out.
Now plug T + R = 130 into Equation 2. We already know this, so we can go back to Equation 1:
T + C = 170
But C = R + 40
So:
T + R + 40 = 170
T + R = 130
Now we can confidently say:
T = 150 cm
That’s the correct answer. The height of the table is 150 centimeters.
