40. There are 400 numbers between 100 and 500 and one in every ten ends in 5.
500
157 of them.
40 palindromes.
They are from 11 squared to 22 squared making a total of 12 square numbers between 100 and 500
If you mean 3-digit numbers whose digits are in decreasing order, then the answer is 20.

There are (500-100)/2 = 200 numbers divisible by 2 between 100 and 500 counting 100 but not 500. Of these (500-100)/8 = 50 are divisible by 8. So there are 150 numbers between 100 and 500 divisible by two but not by 8. By relative primeness exactly 50 out of these 150 are divisible by 3 and therefore these 50 are exactly the ones divisible by 6 but not by 8.

500
100 times because if you do the opposite with the numbers you have, 500/5=100
There are 156 such numbers.
There are 67 numbers between 100 and 500 divisible by 6. The first number greater than 100 divisible by 6: 100 ÷ 6 = 16 r 4 → first number divisible by 6 is 6 × 17 = 102 Last number less than 500 divisible by 6: 500 ÷ 6 = 83 r 2 → last number divisible by 6 is 6 × 83 = 498 → all multiples of 6 between 17 × 6 and 83 × 6 inclusive are the numbers between 100 and 500 that are divisible by 6. → there are 83 - 17 + 1 = 67 such numbers.
The 3 digit numbers under 500 are 100 through 499.
To determine what 100 is between 6308 and 5808, we can calculate the difference between the two numbers. The difference is 6308 - 5808 = 500. Therefore, 100 is 100 out of 500, which means it is 20% of the way from 5808 to 6308. Thus, adding 100 to 5808 gives us 5908, which is where 100 falls between the two numbers.
