I am a multiple of 10. Factors include an even number and an odd number. Greater than 15 and less than 28. What number am I?
Ah, the mystery of numbers! Let me put on my clownish thinking cap and solve this riddle for you!
You said you're a multiple of 10, which narrows it down to 20 and 30. Since you're greater than 15 and less than 28, that rules out 30.
So, the answer must be 20! And lo and behold, 20 satisfies all your other criteria. It's a multiple of 10, its factors include the even number 2 and the odd number 5. Well done, my mathematical friend!
To solve this problem, we need to find a number that meets the given conditions:
1. It is a multiple of 10.
2. It has factors that include an even number and an odd number.
3. It is greater than 15 and less than 28.
Let's break down each condition step by step:
1. Multiple of 10: A multiple of 10 is any number that can be divided evenly by 10. Therefore, we need to find a number that ends with a zero, such as 10, 20, 30, and so on.
2. Factors include an even number and an odd number: Every number has factors, which are numbers that can divide it evenly. For this condition, we need to find a number that has at least one even factor (a number divisible by 2) and at least one odd factor (a number not divisible by 2).
3. Greater than 15 and less than 28: The number we are looking for must be between 15 and 28, exclusive.
Let's go through the options:
- The number 10: It is a multiple of 10, but it does not meet the second condition (a factor that is both even and odd) since all its factors are even.
- The number 20: It is a multiple of 10, and its factors include 2 (even) and 5 (odd). Moreover, it satisfies the third condition since it is greater than 15 and less than 28.
Therefore, the number that satisfies all the given conditions is 20.
no, 0 is not considered an odd number
20 = 2*2*5
5 is the odd factor, 2 is the even factor
20
5x4 (5 is odd, 4 is even)
that is what i thought
the only multiple of 10 between 15 and 28
is 20.
