The digits of a three digit number are in AP&their sum is 15.The number obtained by reversing the digits is 594 less than the original number.Find the number?

  • Maths -

    the ap = a, a+d, a+2d, so

    3a+3d = 15
    a+d=5

    so, the number is 159 or 258 or 357
    reversed, it is either 951 or 852 or 753

    Looks like original is 852 - 258 = 594.
