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?
the ap = a, a+d, a+2d, so
3a+3d = 15
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.
