# What 2 numbers don't belong 67 72 82 95 77 53 97 and 87?

This is an extremely poor question.

There are 28 pairs of numbers and, in less than 10 minutes, I could find reasons why 17 pair were different from the other numbers in the set. A bit more time and I am sure I could do the rest.

So here they are:

53 and 72: leave a remainder of 15 when divided by 19.

53 and 77: leave a remainder of 5 when divided by 12.

53 and 82: leave a remainder of 24 when divided by 29.

53 and 87: leave a remainder of 2 when divided by 17.

53 and 95: leave a remainder of 11 when divided by 21.

53 and 97: leave a remainder of 9 when divided by 11.

67 and 95: leave a remainder of 11 when divided by 28.

67 and 87: leave a remainder of 7 when divided by 17.

67 and 97: leave a remainder of 7 when divided by 30.

72 and 82: leave a remainder of 0 when divided by 2 (are even).

72 and 87: leave a remainder of 0 when divided by 3 (multiples of 3).

72 and 95: leave a remainder of 3 when divided by 23.

72 and 97: leave a remainder of 22 when divided by 25.

77 and 95: leave a remainder of 5 when divided by 9.

77 and 97: leave a remainder of 17 when divided by 20.

82 and 95: leave a remainder of 4 when divided by 13.

87 and 95: leave a remainder of 7 when divided by 8.
