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 ?

Answer 1

These are the prime numbers between 30 and 60

31, 37, 41, 43, 47, 53, 59

Which one of those meets the other criterion?

Answer 2

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.

Answer 3

What is between 30 and is a prime number. The ones is three less than the tens. What number am I.
