Number Analogy Abstract
Number Analogy Abstract
Number Analogy is a crucial step in solving questions on reasoning ability. The candidates are asked to identify and point out relationships, similarities or differences, and dissimilarities in a series or between groups of numbers. In abstract number analogy, certain relationships can be used like product of prime numbers, product of odd numbers or even numbers, adding 1 to a number and many more.
Following are some categories of abstract number analogies.
Example 1 : Product of Prime Numbers : 6 : 15:: 35 : ?
a) 30 b) 40 c) 77 d) 80
Solution: The first few prime numbers (all the prime numbers less than 100) are: 2, 3, 5, 7, 11, 13, 17 etc. 2 X 3 = 6, 3 X 5 = 15, 5 X 7 = 35.
Hence, 7 X 11 = 77. Correct option is (c) i.e. 77
Example 2 : Product of Odd Numbers :- 15 : 35:: 63 : ?
a) 30 b) 99 c) 77 d) 100
Solution : The first few odd numbers (all the odd numbers less than 100) are: 3, 5, 7, 9, 11, 13, 15, 17 etc. 3 X 5 = 15, 5 X 7 = 35, 7 X 9 = 63.
Hence, 9 X 11 = 99. Correct option is 90 (b) i.e. 99.
Example 3 : Product of Even Numbers :- 8 : 24:: 48 : ?
a) 80 b) 100 c) 120 d) 140
Solution : The first few even numbers (all the even numbers less than 100) are: 2, 4, 6, 8, 10, 12, 14, 16 etc. 2 X 4 = 8, 4 X 6 = 24, 6 X 8 = 48. Hence 8 X 10 = 80. Correct option is (a) i.e. 80
Example 4 : Identify the missing term : 8 : 14:: 20 : ?
a) 26 b) 30 c) 40 d) 100
Solution : Identify the terms in the series. Use n : n + k: where "k" is a number.
8 + 6 = 14, 14 + 6 = 20, Hence 20 + 6 = 26. In this question "k" is a constant term whose value is 6. Correct option is (a) i.e. 26.
Example 5 : Identify the missing term : 8 : 32:: 10 : ?
a) 60 b) 30 c) 50 d) 70
Solution : Identify the terms in the series. Use n : : where "n" is the first number.
, Hence, we can find this value for n = 10 ,
Correct option is (c) i.e. 50
