Repaid and Ratio Puzzle

  1. Aug 13, 2009 #1
    Substitute each of the letters by a different digit from 0 to 9 to satisfy this equation. None of the four numbers can contain any leading zero.

    (REPAID)/(DIAPER) = (RA)/(RE)

    Note: Each of the four numbers represent the concatenation of the digits, and does not denote the product of the digits.

    Found solution via brute force: d=2 i=0 a=8 p=7 e=9 r=1
    repaid=197802, diaper=208791
    repaid*re=3758238, diaper*ra=3758238
