When a 3-digit number is divided by a 2-digit number, the quotient is between 5 and 6. What are the numbers using only 8 1 4 7 3?

Answer 1

We know that 5*7=35, so the three digit number probably starts with a 3, and the two digit number starts with a 7.
We also know that we should put small digit after 7, and large digits after 3, so the numbers are
384/71
Check: 5 < 384/71=5.408 < 6
There may be other solutions.
