A three digit number and reversal puzzle

  1. Aug 5, 2008 #1
    A positive 3-digit decimal (base 10) number is such that if we divide the number by 3, reverse the digits of the result, and then subtract 1, we will obtain the original number.

    Determine the number. What is the next greater number (possibly with more than 3 digits) with this property?

    Divide by 3: 247
    Reverse the digits: 742
    Subtract 1: 741, the original number.
    I don't know the next number.
