Answer:

The hundreds digit of 10n is 6

Notice what happens when we multiply any positive integer by 10:

34 x 10 = 340

60 x 10 = 600

128 x 10 = 1280

54629 x 10 = 546290

The tens digit in the original number becomes the hundreds digit in the new number.

So, if we're told that the hundreds digit of 10n is 6, then we know that the tens digit in n must be 6

Since we can answer the target question with certainty, statement 1 is SUFFICIENT
