To determine how many pairs of the given sets of numbers are exactly alike, we need to compare each pair and identify which of them contain matching numbers.

- The first pair, 821421 and 821241, are not identical due to the different arrangement of the digits (the third and fourth digits differ).

- The second pair, 726191 and 726191, is identical as both numbers are the same.

- The third pair, 827015 and 820715, are not identical; the first two digits differ.

- The fourth pair, 287651 and 287651, is identical as both numbers are exactly the same.

- The fifth pair, 009824 and 008924, are not identical; the third and fourth digits differ.

- The last pair, 721182 and 721182, is identical because both numbers are exactly the same.

From this analysis, the pairs that are exactly alike are:

1. 726191 and 726191

2. 287651 and 287651

3. 721182 and 721182

This leads to a total of three identical pairs, which confirms the correct answer.
