In this Number Classification, you are given a pair or group of numbers in which all but one pair or number are related to each other in a certain manner, thus forming a group of pairs or numbers that have the same property. You have to identify an odd number pair or number that does not belong to any other pair group or numbers.
Note that: There is a similarity exists between a given number or group of numbers. You need to identify an odd number or a group of numbers that do not belong to a group.
The number classification ia generally based on the following similarities:
- Square and Square root of a number,
- Cube and Cube root of a number,
- Even & Odd number,
- Prime number,
- Divisibility test of a number,
- Sum of digits of a number etc.
Below you will see pair of numerals in a group. There are four/ five pair of numbers in each group. One numerals pair in each group is different from the rest. You must choose which is the odd numerals pair or a odd numeral.

Then you need to understand this relationship and choose the pair where the words are related differently.
Let's see some example questions for your reference which will definitely help you to get clear about the concept.

Answer Key & Explained solutions for the above questions;
- (c) All numbers are the square of other numbers except 8.
- (d) 115 = 5 × 23 ;
85 = 5 × 17;
95 = 5 × 19; 155 = 5 × 31;
But, 75 = 5 × 15
One factor of 75 is not a Prime Number. - (e) Except for number 345, all other numbers are products of 23
and a Prime Number.
115 = 23 × 5; 161 = 23 × 7
253 = 23 × 11; 391 = 23 × 17
But 345 = 23 × 15.
The number 15 is not a Prime Number. So, 345 is the correct answer. - (e) All other numbers are multiple of 4 except 82.
- (e) All numbers are composite numbers except 149, which is a prime number.
- (d) Except 255 all other numbers are one more than a perfect square.
$50 = (7)^2 + 1, 65 = (8)^2 + 1;$
$170 = (13)^2 + 1, 290 = (27)^2 + 1$
But, $255 = (16)^2 – 1$ - (c) Except 529, all others are perfect squares of even numbers.
The number 529 is a perfect square of an odd number.
196 = 14 × 14; 256 = 16 × 16; 529 = 23 × 23; 576 = 24 × 24 & 324 = 18 × 18. - (c) The product in all other cases is 96.
- (d) The difference in all the other cases is 12.
- (c) $(9 – 7)^2 = 4, (13 – 7)^2 = 36, (11 – 7)^2 = 16,$ But $(9 – 5)^2 ≠ 25$
- (b) In all the rest pairs, the difference is divisible by 3.
- (b) In all other numbers, the sum of the digits is 17.
- (b) In all the rest groups there is no common factor of the two numbers.
- (a) In all other pairs, one number is the square of the other.
- (c) In all other groups, the first number is obtained by adding 2 to the product of the second and the third numbers.
