Answer 2

To determine the divisibility of the given numbers, let's analyze each condition:

A) Divisible by 9: To check if a number is divisible by 9, you can sum up its digits and see if the resulting sum is divisible by 9.

For 67086: 6 + 7 + 0 + 8 + 6 = 27

For 34115: 3 + 4 + 1 + 1 + 5 = 14

For 41195: 4 + 1 + 1 + 9 + 5 = 20

For 45892: 4 + 5 + 8 + 9 + 2 = 28

For 205711: 2 + 0 + 5 + 7 + 1 + 1 = 16

None of these numbers have sums that are divisible by 9, so none of them fulfill condition A.

B) Divisible by 11: To check if a number is divisible by 11, you can compute the alternating sum of its digits (subtract one digit from the next, then add the next digit, and so on) and see if the result is divisible by 11.

For 67086: (6 - 7) + (0 - 8) + 6 = -3

For 34115: (3 - 4) + (1 - 1) + 5 = 3

For 41195: (4 - 1) + (1 - 9) + 5 = 0

For 45892: (4 - 5) + (8 - 9) + 2 = 0

For 205711: (2 - 0) + (5 - 7) + (1 - 1) = 0

None of these numbers have alternating digit sums that are divisible by 11, so none of them fulfill condition B.

C) Divisible by 9 and 11: Since none of the numbers fulfill conditions A or B, none of them are divisible by both 9 and 11. Thus, condition C is not fulfilled either.

D) Divisible by 11 or 9: Based on the results from conditions A and B, none of the given numbers are divisible by either 11 or 9. Therefore, none of the numbers fulfill condition D.

In conclusion, among the given numbers, none of them satisfy any of the provided conditions (A, B, C, or D).
