To find how many numbers between 1 and 99 contain the digit '2', we can analyze both the tens and units places. In the tens place, the numbers are 20-29, giving us 10 occurrences. For the units place, the numbers with '2' are 2, 12, 22, 32, 42, 52, 62, 72, 82, and 92, totaling 10 occurrences. Therefore, the total count of numbers between 1 and 99 that contain the digit '2' is 19 (10 from the tens place and 9 additional from the units place, excluding 22 which was counted twice).
To find how many times the digit '3' appears between 300 and 400, we look at the numbers from 300 to 399. The hundreds place always has '3' for these numbers, contributing one '3' for each of the 100 numbers (300 to 399). Additionally, the '3' appears in the tens place in the numbers 330 to 339, contributing another 10 occurrences. In total, there are 1 (from the hundreds place) + 10 (from the tens place) = 11 occurrences of the digit '3' between 300 and 400.
To find how many times the digit 2 occurs in the tens place from 100 to 1000, we can analyze the range of numbers. The relevant range for the tens place is from 120 to 229, which includes all numbers where the tens digit is 2. This gives us the numbers 120-129 (10 occurrences), 220-229 (10 occurrences), totaling 20 occurrences of the digit 2 in the tens place.
