3x3 square and common sum puzzle

  1. Aug 11, 2009 #1
    Substitute each of the capital letters by a different digit from 0 to 9, such that each of the columns, each of the rows and each of the two main diagonals of this 3x3 square have the common sum LRK. It is known that L is nonzero and, each of the numbers in the nine cells contains non leading zero.

    Assuming that you mean LRK = 100*L + 10*R + K and not the product L*R*K I get:
    a = 2 b=0 c=3 e=9 h=5 k=4 l=1 o=6 r=7 s=8
    lrk=174
