Reasoning (Verbal) : Classification
Example 2. Find the odd man out.
- (1) AK
- (2) CM
- (3) EP
- (4) DN
- (5) None of these
Solution. (3) Except EP {option (3) }, the rest has a gap of 10 letters between them.
Number Analogy
Typical relationships between the numbers in a given pair can be any of the following :
- One number is a multiple of the other.
- the One number is the square or square root of the other.
- One number is the cube or cube root of the other.
- The 2 numbers can be consecutive, even, odd or prime numbers.
Example 1: 3 : 81 : : 6 : ?
- (a) 1296
(b) 1269
(c) 1692
(d) 1926
Solution. (a) n : n4 relation here (3) and (3)4 = (81)
Similarly, (6) and (6)4 = 1296
Number Series
Prime Number Series:
Example 1. 4, 9, 25, 49, 121, 169,…
(a) 324 (b) 289 (c) 225 (d) 196
Solution. (b) The next prime number is 289.
Multiplication Series:
Example 2, 4, 8, 16, 32…
(a) 56 (b) 64 (c) 86 (d) 106
Solution. (a) The numbers are multiplied by 2 to get the next number. 32 × 2 = 64
Difference Series:
Example 4, 7, 10, 13, 16,…. 22
(a) 16 (b) 17 (c) 20 (d) 19
Solution. (d) The difference between the numbers is 3. = 16 + 3 = 19
Division Series:
Example. 5040, 720, 120, 24, ….2,1
(a) 8 (b) 7 (c) 6 (d) 5 Solution. (c)
Coding – Decoding
Blood Relations
In such problems, the aptitude of aspirants is shown by the knowledge of the various blood relations. The typical relationships that are commonly used in blood relation problems are summarized as follows
- Father’s or Mother’s son = Brother
- Father’s or Mother’s daughter = Sister
- Father’s or Mother’s brother = Uncle
- Father’s or Mother’s sister = Aunt
- Father’s or Mother’s father = Grandfather
- Father’s or Mother’s mother = Grandmother
- Brother’s or Sister’s Son = Nephew
- Brother’s or Sister’s Daughter = Niece
- Uncle’s or Aunt’s son or daughter = Cousin
- Sister’s Husband = Brother-in-law
- Brother’s wife = Sister-in-law
- Son’s wife = Daughter-in-law
- Daughter’s Husband = Son-in-law
- Husband’s or wife’s sister = Sister-in-law
- Husband’s or wife’s Brother = Brother-in-law
Direction Test

(a) East
(b) West
(c) North
(d) None of these
Solution: (b)
Sitting Arrangements
For Rectangular Arrangement
A <-> B (Front with each other)
C<-> D (Front with watch other)
For Hexagonal Arrangement
A <-> D (Front with each other)
B <-> E (Front with each other)
C <->F (Front with each other)

Symbols and Notations
Symbols for these types of questions stand for mathematical operations like +, –, ×, ÷, > , <, ³, £, = and #. So, the candidates must replace the symbols by mathematical operations and apply the :””BODMAS’”” rule to find the value of the given expression. Other symbols which can be used are DÑ, *, @, $, etc, with proper definitions. Some examples are given below
Example 1: If ‘+’ means ‘–’, ‘–’ means ‘×’, ‘×’ means and ‘means’ ‘÷’, and ‘÷’ mean ‘+’ then 15 × 3 ÷ 15 + 5 – 2 = ?
- 0
- 10
- 20
- 6 Solution. (b): 15 × 3 = 15 + 5 – 2 after changing the signs = 15 = 3 + 15 – 5 × 2 = 5 + 15 – 10 =10

Reasoning Input/ Output Example
Directions :- A word arrangement machine, when given an input line of words, rearranges them following a particular rule in each step. The following is the illustration of the Input and the steps of arrangement:
Input: Mahesh mood varies with time and environment
Step I: varies with Mahesh mood environment and time
Step II: and time environment mood Mahesh varies with
Step III: environment time and varies with mood Mahesh
Step-IV: and varies environment time Mahesh mood with
And so on for subsequent steps. You have to find out the logic and answer the questions given below.
