There is a number between 30 and 60. It is a prime number. The digit in the ones place is three less than the digit in the tens place. What is the number? *
Let's see, some options we have are:
31, 37, 41, 43, 47, 53, and 59.
So our answer must be 47 as the digit in the one's place (4) is three less than the digit in the ten's place (7).
Sorry, I meant 41, not 47.
