How many times does the digit 1 occur in ten place in the numbers from 1 to 1000?
That looks like it should be the same as 10 times (the number of times the digit 1 occursin the units place in the numbers from 10 to 100), which would work out to 90 .

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.

To find how many times the digit 3 occurs in the hundreds place for numbers between 100 and 10,000, we consider all three-digit and four-digit numbers. The hundreds place can be 3 in the range from 300 to 399, which gives us 100 occurrences (300 to 399 inclusive). For four-digit numbers, the hundreds place can also be 3, covering the range from 3,000 to 3,999, which again totals 1,000 occurrences. Therefore, the digit 3 occurs 1,100 times in the hundreds place from 100 to 10,000.
