Riddle: What is the smallest whole number that is equal to seven times the sum of its digits?
Answer: The answer to this math riddle is 21. You probably just guessed to answer this math riddle, which is fine, but you can also work it out algebraically. The two-digit number ab stands for 10a + b since the first digit represents 10s 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. The smallest such number is 21.

Riddle: There are four words. Two of them have four letters, and the other two have five letters. The four-letter words have two vowels and two consonants. The five-letter words have two vowels and three consonants. If you read one of the four-letter words backward, you will get the other four-letter word. If you put a consonant in the beginning of a four-letter word you'll get one of the five-letter words. If you put the same consonant to the end of the other four-letter word you will get the other five-letter word, which is also read backward as the first five-letter word. There is a correlation between the one of the four and one of the five-letter words. The same goes for the other two words. One pair has to do with something bad and the other pair has to do with life. What are the words?

Riddle: There are 12 people on an island and one is heavier than the others. You have to figure out which Islander is the heaviest using a seesaw. But you can only use the seesaw 3 times. How do you figure out which one is heavier?
Answer: First, you do six and six. If one of the six is heavier, then you do three and three. Then if one of the three is heavier than you do one and one. If the second or first one on the seesaw on heavier, than that is the answer. But if none of them are heavier then you know that the one that is not on the seesaw is heavier.
