How many 5 digit numbers can be formed using 0 2 3 4 and 5 when repetition is allowed such that number formed is divisible by 2 or 5 or both?
2000 is the answer.
(explanation)
There are four choices for the first digit since it cannot be zero . ( We do not
consider something like 01234 to be a 5-digit number.)
Any of the five choices will do for the second, third and fourth digits.
The last digit must be 0,2,4, or 5 to make it divisible by 2 or 5 or both.
Therefore, there are 4 x 5 x 5 x 5 x 4 = 2000 possibilities in all.

How many 3 digit numbers can be formed from digits 0 1 2 3 4 5 6 7 8 9 and what are the results?
If repetition is allowed and leading zeros are allowed, then you have 000 to 999, which is 1,000 possibilities (I will not list them here). If no leading zeros are allowed, then you have 100 through 999, so there are 900 possibilities.

How many five digit numbers can be formed using the digits 0 2 3 4 and 5 when repetition is allowed such that the number formed is divisible by 2 or 5 or both?
"Divisible by two" means the number can end with 0,2, or 4."Divisible by five" means the number can end with 0 or 5.Combined that means the ONLY digit the number cannot end with is 3; it can end with any of the other four.Also, I'm presuming that it's not a "five digit number" if it starts with a 0, so only four of the digits are legal there.All told, there are 4 x 5 x 5 x 5 x 4 possibilities. That's 2000 different possible numbers.
