Let's break down the riddle:
>
"Multiply this number with any other number and you will get the same answer every time. What is the number?"
We are looking for a number that, when multiplied by
any other number, always gives the
same result.
Let’s think about what happens when we multiply numbers:
- If you multiply 5 × 2 = 10
- 5 × 3 = 15 → different result
So clearly, most numbers give different results.
But suppose we try
zero:
- 0 × 5 = 0
- 0 × 10 = 0
- 0 × (-3) = 0
- 0 × 0 = 0
No matter what number you multiply by zero, the result is
always 0.
So the answer is:
0
---
✔ Final Answer: 0
Because multiplying
any number by
0 always gives
0, which is the same answer every time.
This satisfies the condition in the riddle perfectly.
