The pair of numbers that does not belong to the group for lack of common property? 18, 45 27, 36 29, 82 14, 23
- 18, 45
- 27, 36
- 29, 82
- 14, 23
Explanation
All pairs except one have a common property inside the pair.
18 = 1+8 = 9 and 45 = 4+5 = 9
27 = 2+7 = 9 and 36 = 3+6 = 9
14 = 1+4 = 5 and 23 = 2+3 = 5
In every pair the sum of digits of both numbers is equal.
In 29, 82
29 = 2+9 = 11
82 = 8+2 = 10
Sum is not equal.
So 29, 82 does not belong to the group.
