Question 413188: place the digits 3,5,6,8 in the boxes below to get the largest possible product. BOXES BELOW ARE TO EMPTY SQUARES ON TOP X TWO SQUARES UNDER NEATH ON THE BOTTOM. Found 2 solutions by Edwin McCravy, solver91311:Answer by Edwin McCravy(20086) (Show Source):
The largest product has to be when the largest
two digits 6 and 8 come first to contribute the
most number of tens possible. So we just have
to try these two possibilities:
63 65
×85×83
315 195
50405200
5355 5395
and we see that the one on the right is the larger product.
