A number is between 150 and 200. A sum of the digits is 12. If you subtract the ones digit from the tens digit, the difference is 5. What is the number?

    Let the number be ABC, which is between 150 and 200, so A=1. (minimum is 151 and maximum is 199)

    A+B+C = 12

    so 1+B+C=12

    and B-C=5

    solve to find B and C
