This common question is ambiguous and needs more detail. Variations of the answer with explanations are below. The most commonly asked form of this question deals with 6's so that is what shall be used in my answer. (If you do not understand, replace the 6's in my answer with 8's.)
[Literal Sense]
1 is the answer because the actual number '6' (by itself) only occurs once.
[The Digit 6]
20 is the answer because, the digit 6 appears 20 times in this example:
6, 16, 26, 36, 46, 56, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 76, 86, 96
[The Number 6]
10 is the answer.
These would be the numbers in which '6' occurs:
6, 16, 26, 36, 46, 56, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 76, 86, 96
This is because one does not count the digits that represent values other than 6 (i.e. 60, 600, 6000, etc.). So, in this case, the digits with a strikethrough are uncounted. Simply, 6's are only counted in the ones place value.

7,17,27,37,47,57,67,70,71,72,73,74,75,76,77(two sevens),78,79,87,97=20 times
11? there are more than 11. There are 20. 6 16 26 36 46 56 60 61 62 63 64 65 66 67 68 69 76 86 96 Can anyone argue this?
There are several ways to increment a variable:$count = $count +1;$count += 1;$count++;++$count;
Double 10 is 2 x 10 which is 20, so now, just add all these numbers… 10 10 20 45 15. The answer is 100. This is actually the answer to the old riddle… What is 10, 10, double 10, 45, 15? Others say it’s the fastest way to count to 100! Still others say the fastest way to count to 100 is… 99 cows and a bobtailed bull!
you would pass ten on the way.

10 would be the answer.
If you count from 1 to 100 you pass 11 6's along the way: 6, 16, 26, 36, 46, 56, 66, 76, 86, and 96.

7,17,27,37,47,57,67,70,71,72,73,74,75,76,77(two sevens),78,79,87,97=20 times
You will only pass 1! The reason is You will pass 6 one time not 16 or 26 or any higher its 6! so u will pass it once
The correct answer should be 20:6,16,26,36,46,56,60,61,62,63,64,65,66,67,68,69,76,86,96(66 is a double 6).
If you count from one to one-hundred, you will pass nineteen six's.
