Just make cases
It might take a few seconds extra bit lands you on the correct answer just the same

596__ = 7×6 = 42 ways (distinct)
59_6_ = 42
59__6 = 42
5_96_ = 42
5_9_6 = 42
5__96 = 42

252 in total

We can’t do this for a number starting with 6 because 9 has to be on the left of 6

70,000 , 80,000 will have the same principle so 252 in each as well

For last case
96___ = 8×7×6 = 336 ways
9_6__ = 336
9__6_ = 336
9___6 = 336

Therefore (252×3) + (336×4) = 2100

Looks lengthy cause I stated each step but it’s rather quick if you’re decent with your calculations

Hopefully the answer is clear now
