TNPSC – CODING AND DECODING

TNPSC – CODING AND DECODING

Analogy literally means ‘similarity’ or having similar features. Questions on analogy test the ability of a candidate to understand the relationship between two given objects or words or numbers that are asked in the question. These type of questions cover all types of relationships that one can think of, there are many ways of establishing a relationship.

Types of questions:

 Type I : Word Analogy

1. Ocean : Pond :: Kilometer : ?

A) Volt

B) River

C) Meter

D) Second

E) Kilogram

Soln: C)

As ‘Pond’ is a small unit of ‘Ocean’, similarly ‘Meter’ is a small unit of ‘Kilometer’.

Thus, ? is Meter

Type II: Letter Analogy

2. LMNO : MNOP :: STUD : ?

A) TUVW

B) TUEV

C) TUVE

D) TIVE

E) None of these

Soln: C)

Here, we observe that each letter of ‘LMNO’ is increasing by 1.

Similarly,

Thus, ? => TUVE

 

Type III: Number Analogy

3. 635768 : 867536 :: 819578 : ?

A) 785918

B) 875981

C) 875819

D) 818759

E) None of these

Soln: E) 635768 is 867536

Here, we observe that all the digits of number ‘635768’ are written in reverse order.

Similarly, 819578 is 875918

Thus, ? is 875918

Type IV: Letter and Number Analogy

4. MET : 14227 :: DAM : ?

A) 23263

B) 232613

C) 236213

D) 232614

E) None of these

Soln. D) 232614

Reverse letter places i.e. if M is the 13th letter from the beginning, then N is the 13th letter from the back, i.e. when we count from ‘z’.

Here, we observe that the each letter of ‘MET’ is numbered in reverse order.

Similarly, Thus, ? is 232614

5. M/S : 13/19 :: K/J : ?

A) 10/11

B) 11/10

C) 14/20

D) 22/21

E) 11/15

Soln. B) 11/10

Here, we observe that the right side number is the position of the corresponding left side letter in the alphabet.

Similarly,

Thus, ? = 11/10
