How many digits are there in the numbers 1 to 99?
There are a total of 189 digits in the numbers 1 to 99. To calculate this, we can consider the numbers from 1 to 9, which have a total of 9 digits. Then, we add the numbers from 10 to 99, which have 2 digits each, for a total of 2 * 90 = 180 digits. Adding these together gives us 9 + 180 = 189 digits in total.
How many odd four digit numbers can be formed from the digits 1 2 3 and 4?

How many digits are there between 1 and 1000?
Not couting 1 and 1000, there would be 998 numbers.
How many digits are there in all numbers inclusive from 1 to 1000?
Infinitely many. The number pi , for example, is between 1 and 1000 and, since pi is a transcendental number, it contains infinitely many digits. Plus, there are all the irrational numbers - each with infinitely many digits, and all the rationals with recurring decimals - again with infinitely many digits.
How many digits are there in the numbers 1-10000?
10001
How many digits are there from 1 to 1000?
There are 2892 digits.
How many numbers are there between 100 and 1000 such that one of their digits is 6?
I suggest you calculate (1) how many numbers are in total, and (2) how many numbers in that range do NOT have 6 as a digit. Then you can subtract the result of (1) minus the result of (2).
How many digits 1 through1000?
2893 digits in all, made up as follows: 9 1-digit numbers (1 to 9) = 1*9 = 9 digits 90 2-digit numbers (10 to 99) = 2*90 = 180 digits 900 3-digit numbers (100 to 999) = 3*900 = 270 digit 1 4-digit number (1000) = 4*1 = 4 digits
How many palindromic numbers in 1000-10000?

Using only arrangements of the given digits: without repeating digits, 15. with repetition, 39. The answer does not include numbers such as 2^3 = 8 or 3^(2+1) = 27
How many prime numbers are there whose square has 5 or 6 digits?
solution: we know that there are 25 prime numbers are between 1-100 and 168 prime numbers less than 1000. 100 x 100=10000(5 digits) 999 x 999=998001(6 digits) 1000 x 1000=1000000(7 digits) so our answer should be same as the number of prime numbers between 100 to 999. hence, 168-25=143. 143 prime numbers will be there less than 1000 whose square has 5 or 6 digits.
