How many times does the digit 2 occur between the numbers 1 and 1000?

Answer 1

Consider the following numbers between 1 and 10 inclusive:
2, 12, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 32, 42, 52, 62, 72, 82, 92.
So we have 20 twos between 1 and 99 inclusive.
It will be the same for each hundred.
1 to 99 gives 20 twos.
100 to 199 gives 20 twos.
300 to 399 gives 20 twos.
400 to 499 gives 20 twos.
500 to 599 gives 20 twos.
600 to 699 gives 20 twos.
700 to 799 gives 20 twos.
800 to 899 gives 20 twos.
900 to 1000 gives 20 twos.
and
200 to 299 gives 20 twos and also 100 twos because the 200 range of numbers start with a two.

(20x10) + 100 = 300 twos.

Answer 2

from 1 to 100, it occurs 10 times as the second number (2-92) and 10 as the first (20-29), so 20 total. this also works for the 100s and the 300s to 1000, which is 8 more times. that makes 180 right there. for the 200s, it occurs 100 times as the first number, 10 as the second and 10 as the third, which is 120. so my answer is 180 + 120 = 300.
