I am a number between 30 and 60 . My ones digit is three less than my tens digit . I am a prime number . What number am I ?
These are the prime numbers between 30 and 60
31, 37, 41, 43, 47, 53, 59
Which one of those meets the other criterion?
To find the answer to this question, we will go through the given conditions step by step.
First, we know that the number is between 30 and 60. This means we can start with the lowest possible number, which is 31, and check if it meets the other conditions.
Next, it is mentioned that the ones digit is three less than the tens digit. This means the tens digit should be three more than the ones digit. So, let's check if 31 satisfies this condition. The tens digit of 31 is 3 and the ones digit is 1. Since 3 is indeed three more than 1, this condition is also met.
Now, we need to check if the number is a prime number. A prime number is a number greater than 1 that is divisible only by 1 and itself. So, let's check if 31 is divisible by any number other than 1 and itself. We can start by dividing it by 2, 3, and so on, until the square root of 31 (which is approximately 5.57). After checking, we find that 31 is not divisible by any of these numbers, so it is a prime number.
Therefore, the number that satisfies all the given conditions is 31.
What is between 30 and is a prime number. The ones is three less than the tens. What number am I.
tens digit = X.
ones digit = x - 3.
10x + (x-3) = 11x - 3 = the number.
30 < 11x-3 < 60.
33 < 11x < 63,
3 < x < 5 8/11.
X = 4 or 5.
Let x = 4.
11x - 3 = 11*4 - 3 = 41 = the prime number between 30 and 60.
