There are 4*3 = 12 such numbers.
To write the numbers from 1 to 20, we need to count the digits used for each range. The numbers 1 to 9 use 1 digit each, totaling 9 digits. The numbers 10 to 20 use 2 digits each, totaling 22 digits (11 numbers). Therefore, the total number of digits required to write all the numbers from 1 to 20 is 9 + 22 = 31 digits.

To find the total number of digits used to print the numbers from 1 to 11,521, we can break it down by the number of digits in each range. From 1 to 9 (9 numbers) uses 9 digits, from 10 to 99 (90 numbers) uses 180 digits, from 100 to 999 (900 numbers) uses 2,700 digits, and from 1,000 to 11,521 (10,522 numbers) uses 42,088 digits. Adding these together, the total is 9 + 180 + 2,700 + 42,088 = 44,977 digits.
