All the numbers from 500 to 599 EXCEPT 500, 511, 522, 533, 544, 550 - 559, 566, 577, 588 & 599. That is 100 less 19 ie 81.
If you regard 505 as being a repetition then there are 9 less overall.

How many odd 3- digit positive integers can be written using the digits 1 2 4 7 and 8?

How many whole numbers have exactly three digits how did you find that out and tell me why that's the answer?
Assuming that 001, 080, etc are not allowed (that is a leading zero or two is not permitted), the smallest number with exactly three digits is 100. The largest number with exactly three digits is 999. So there are 999 - 100 + 1 = 900 numbers with exactly three digits.
How many four digits numbers can be formed using 0578?
If the digits are all different then 18. Otherwise, 192.
How many 6 digit numbers can be formed with 1 to 45 digits?
Assuming all 45 digits are different (which they will not be if they are ordinary integers), then 456, if repetitions are allowed. That is 8303765625. If repetitions are not allowed then the number falls to 45*44*43*42*41*40 = 5864443200

How many 3 digit number can be made using the digits 2 4 7 9?
24 three digit numbers if repetition of digits is not allowed. 4P3 = 24.If repetition of digits is allowed then we have:For 3 repetitions, 4 three digit numbers.For 2 repetitions, 36 three digit numbers.So we have a total of 64 three digit numbers if repetition of digits is allowed.

How many 3 digit numbers are possible from the digits 012345?
Assuming that the first digit can't be zero: If repetition of digits is permitted: (5 x 6 x 6) = 180 numbers of 3 digits. If repetition of digits is not permitted: (5 x 5 x 4) = 100 numbers of 3 digits.
