Ponder This

April 2013

<<March April May>>


Ponder This Challenge:

This month's challenge is based on a suggestion by Kerry M. Soileau (thanks!).

One can replace the letters in the expression I/M = B/A+C/K with different digits from 1 to 6 to form a valid equation. For example: 5/6 = 2/4+1/3.
Substituting back letters to digits, using the same solution ACK.IBM is 413.526.

The problem: Replace the letters with different digits such that D/O+N/T = P/E+R/I+S/H
and send us PONDER.THIS translated back to a number.
