Winnie wrote the following riddle: I am a number between 60 and 100. My ones digit is six less than my tens digit. I am a prime number. What number does Winnie's Riddle Describe?

Question

help please <3

Answer 1

Let the tens number be x and one number be y.

Then given,

x = y + 6

So the number can be

(x,y) = {60,71,82,93}

out of which only 71 is prime.

So the number is 71
