91 * * * * * That is clearly a nonsense answer. There are at least 100 between 700 and 799! The correct answer is 271.
There are 168 prime numbers between 1 & 1000.
1000 numbers. From 19,500 to 20,499 all round to 20,000
-9999. Or, if only positive numbers are being considered, then, 1000.
Let's represent the two 4-digit numbers as ABCD and WXYZ, where A, B, C, D, W, X, Y, and Z are digits. The difference between the two numbers is 5639, so we can write the equation as 1000A + 100B + 10C + D - (1000W + 100X + 10Y + Z) = 5639. Simplifying this equation, we get 1000(A-W) + 100(B-X) + 10(C-Y) + (D-Z) = 5639. Since the difference between the two numbers is 5639, and the numbers are 4-digit numbers, we can conclude that the numbers are 8194 and 2555.
A four digit whole number can be found from 1000 to 9999
By including the number 1000, the digit 1.

If you count 0000 to 9999 you have 10,000. For whole numbers you have 9999. * * * * * Not sure about "whole" numbers. There are 10,000 in all, of which 9000 (from 1000 to 9999) do not have leading 0s.
