Problems & Puzzles:
Misprinted product, find the correct one
In the entry
1310 of the always interesting site of Claudio Meller we find a
puzzle original by Ady Tzidon, that I have made a little bit more
difficult (I suppose).
In one line of the output
printing of a code we get this wrong product:
536572733725788 x 523674548245792 =
Analyzing the code we find that for some reason each digit
of A, B & C has been increased or decreased exactly by one
the three members of the correct product (P, Q & R such that
P*Q=R is correct). BTW, in this case P & Q are prime numbers.
Contibutions came from Giovanni Resta, Jan van Delden, J. K. Andersen,
Flavio Torasso, Emmanuel Vantieghem, Hakan Summakoglu y Pablo Sussi.
All of them computed the same and correct answer:
425463842614697 * 634563657334681 = 269983892033249234577058406657
