The "3 ten thousands" part means that your number will be
_3_,_ _ _
Now fill in the rest of the numbers with the largest digits.
938,765

The way I interpret your question:
You want a 6 digit number, no zeros, where the ten thousand position is a 3
eg. 436,127, or ?3?,???
if that is the case, the question is quite simple.
9x1x8x7x6x5
= 15120
= the total number of such numbers
the largest such number would of course be
938765
