Multiples of 3 are easy to identify. Their digits add up to a multiple of 3.
60 numbers
45 multiples of 2 plus 30 multiples of 3 minus 15 multiples of 6 equals 60 numbers
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.

There are infinitely many multiples of ten. There are infinitely many sets of 2, 3, 4, ..., infinitely many numbers that add up each one of the multiples of ten. It is, therefore, impossible to answer the question.There are infinitely many multiples of ten.

There are 16 multiples of 6 in that range.
33 multiples of 3 10 multiples of 10 -3 multiples of both 40 total
There are 16 numbers from 1 to 101 that are divisible by 3 and are even.
