Since I must be greater than 75 and less than 100, I can only be a two digit number whose first digit is one of these 3 digits: 7, 8 and 9.
Since my first digit is three times my second digit, this means that my first digit is divisible by 3,
The only one divisible by 3 is 9. (neither 7 nor 8 are divisible by 9).
So, my first digit is 9.
And again, because my first digit is three times my second digits, this means that my second digit is 3.

I am 93! Yes! Yes! Yes... I finally know myself!
