Time for some riddles! Everybody likes a riddle or two from time to time. They keep our minds sharp and let us explore the many possible answers that arise. Number riddles are some of the most popular riddles you can find on the internet. They are easy to memorize, but hard to crack at first. But once you crack them — there is nothing better. Once you crack one number riddle, high chances are you will try to solve another one. But, while being both simple in their design and hard with their answers, why are riddles with numbers so fun?
When we juggle math every day, from the prices of groceries to how much time we spend on a given task, numbers are nothing to us. Or at least, it seems so. Math riddles overall are some of the most brain-moving riddles we can solve. They take time and patience, and sometimes it seems that even the most obvious answers are incorrect. If you can solve a simple math riddle, how are riddles involving numbers, where there is more text, different? The answer sleeps in complexity. These riddles seem to be easy, but they are able to mix in some wordplay magic. They are more like logic riddles, with a focus given on the trickery part. And that is where the whole fun part of the riddle comes from.

What is the smallest whole number that is equal to seven times the sum of its digits?
Linas Simonaitis 2 years ago
Answer: The answer is 21. The two-digit number ab stands for 10a + b since the first digit represents tens and the second represents units. If 10a + b = 7(a + b), then 10a + b = 7a + 7b, and so 3a = 6b, or, more simply, a = 2b. That is, the second digit must be twice the first.
