between 1 and 10, there are 5 different numbers which can be divided by 2. Thus, there are 5*10 numbers within one hundred numbers which can be divided by 2.neilcao wrote:between 100-999, how many number can be divided by 2, or multiples of 2 ?

This applies to the numbers starting from 101 to 1000. Therefore, you have 5*10*9. However, you have to add one for the missing 100 and subtract one for the 1000 which should not be included in the range.
Thus, the answer is: 5*10*9+1-1=450

All even integers between 100 and 999 are divisible by 2.
Number of even integers between 100 and 999 = (999 - 100 + 1)/2 = 450
So, there are 450 even integers between 100 and 999 and hence 450 integers between 100 and 999 can be divided by 2.
Number of even integers between 100 and 999 = (999 - 100 + 1)/2 = 450
So, there are 450 even integers between 100 and 999 and hence 450 integers between 100 and 999 can be divided by 2.
