Specify whether you are including the numbers between 0000 and 1000.
Multiple of both 2 and 3 <=> multiple of 6 So require 2 digit multiples of 6. 2*6 = 12 and 16*6=96 So the answer is 16-2+1 = 15
Three-digit counting numbers range from 100 to 999. To find how many of these are multiples of 2, we note that the smallest three-digit multiple of 2 is 100, and the largest is 998. The sequence of three-digit multiples of 2 can be represented as 100, 102, 104, ..., 998, which forms an arithmetic sequence with a common difference of 2. The total number of terms in this sequence can be calculated as ((998 - 100) / 2 + 1), resulting in 450 three-digit counting numbers that are multiples of 2.

72. (with the range of two digit numbers being from 10 to 99).
The number is 42.

It would help to know which digit. 0 appears in 9 numbers and each of the others in 18 numbers.
That refers to any number that is a multiple of 2. Such numbers can be easily recognized by the fact that their last digit is a multiple of 2, i.e., the last digit is one of (0, 2, 4, 6, 8).
The answer will depend on how many digits there are in each of the 30 numbers. If the 30 numbers are all 6-digit numbers then the answer is NONE! If the 30 numbers are the first 30 counting numbers then there are 126 combinations of five 1-digit numbers, 1764 combinations of three 1-digit numbers and one 2-digit number, and 1710 combinations of one 1-digit number and two 2-digit numbers. That makes a total of 3600 5-digit combinations.
