I believe the number you are looking for is 96.
No. To find if a number is a factor of 3, add the number's digits. If the resulting number is a multiple of 3, then the original number is a multiple of 3. In 4339, the digits of the number added together is 19, which is not a multiple of 3.

Its either 75 or 87 because I do not know if "sum" means the numbers added together (e.g 7+5) or if it is the actual number. 75 works for both, the actual number and them added together, 87 only works for them added together.

A two digit number whose two digits added together equal 42 and multiplied together equal 82

5.25 is a number between 5.2 and 5.3. or any number of digits added after the .2 and before the .3 like 5.2000000000001 and 5.299999999999999999999

This follows from the property that the set of integers is closed under addition. This means that any two integers, when added together, must always result in a whole number.
45
Because it may have a deciml in it
add all the numbers together. 10,12,15,13=40 then divide by the number of digits you added together. 40 divided by 4 is 10 the average is 10
19
Two (or four) digits added together cannot equal 42. Two-digit numbers multiplied together cannot equal 82.
