The digit 5 appears 20 times in the numbers from 1 to 100.
Here's a breakdown:
- Numbers with 5 in the ones place: 5, 15, 25, 35, 45, 55, 65, 75, 85, 95. This is a total of 10 times.
- Numbers with 5 in the tens place: 50, 51, 52, 53, 54, 55, 56, 57, 58, 59. This is also 10 times.
- Note that the number 55 includes two instances of the digit 5, which are both included in the above analysis.
As the reference states, "Number 5 occurs 20 times in the range from 1 to 100. In the number 55, number 5 occurs two(2) times. Hence, it becomes clear that the number 5 occurs 20 times in the range of numbers from 1 to 100."
Therefore, the total count is 10 (ones place) + 10 (tens place) = 20.
