Description In this type of questions, certain pairs/groups of numbers are given out of which all except one are similar in some manner while one is different. The numbers in these similar pairs may have the same property or may be related to each other according to the same rule. The candidate is required to choose the odd pair/group.
EXAMPLES
Directions: Choose the numeral pair group which is different from others.
Example. 1.
(a) 83 - 75
(b) 58 - 50
(c) 49 - 42
(d) 25 - 17
Ans. Clearly, in each of the pairs except (c), the first number is eight more than the second. Hence, the answer is (c).
Example. 2.
(a) 70 - 80
(b) 54 - 62
(c) 28 - 32
(d) 21 - 24
(e) 14 - 16
Ans. In each of the pairs except (b), the ratio of the two numbers is 7 : 8. Hence, the answer is (b).
Example. 3.
(a) 42 - 4
(b) 36 - 6
(c) 32 - 2
(d) 15 - 5
Ans. In all the pairs except (a), the first number is a multiple of the second.Hence, the answer is (a).
Example. 4.
(a) 71,7,3,17
(b) 67,71,3,5
(c) 41,5,3,47
(d) 37, 14, 19, 7
(e) 11, 3, 3, 17
Ans. All other pairs except (d) consist of prime numbers only, while (d) consists of one composite number i.e., 14. Hence, the answer is (d).’

Wat Crap.
We can get different explanations for different options.
In Example 3 : I choose option(a) because the in the other three options, the units digit is taken as the other number.
However in this case, I was lucky to get the right option, but it is not always the case
