Reasoning

Reasoning (including Mathematical)

The strategy which I'm gonna discuss here will help you in other exams also.

After filling in the required details in the paper, flip over to the last page where you are supposed to do your rough work. Quickly write down the following table.

• 1  A Z 26
• 2  B Y 25
• 3  C X 24
• 4  D W 23
• 5  E V 22
• 6  F U 21
• 7  G T 20
• 8  H S 19
• 9   I  R 18
• 10 J Q 17
• 11 K P 16
• 12 L O 15
• 13 M N 14.

This table will help you in solving coding-decoding type questions. By using it you'll know the exact position of each letter both in forward and backward directions. Moreover you know which letter is opposite of, for example, D when direction is reversed. It is W.

This question was given in December 2008.

The letter in the first set have a certain relationship. On the basis of this relationship mark the right choice for the second set:

AST : BRU :: NQV : ?

(A) ORW

(B) MPU

(C) MRW

(D) OPW

Solution.

Write down their numerical position.

AST= 1 19 20

BRU= 2 18 21

Now through the numbers the relationship is evident. 1 i.e. A has become 2 i.e. B. The first letter has moved forward. 19 i.e. S becomes 18 i.e. R. The second letter has moved backward. The third letter has moved forward. So the same rule will be followed to find the answer.

NQV= 14, 17, 22. It will become 15, 16, 23 (OPW) So the correct answer is (D).

The following question was asked in June 2008 and December 2009 UGC NET Exam.

What will be the next term in the following?

DCXW, FEVU, HGTS, ?

(A) AKPO

(B) ABYZ

(C) JIRQ

(D) LMRS

Solution.

DCXW (4,3,24,23)

FEVU  (6,5,22,21)

HGTS  (8,7,20,19). The first two letters are moving forward (+2) and the last two letters are moving backward (-2). Follow the same rule. 8 will become 10 (J) and 7 will become 9 (I). From here itself the answer is clear i.e. option (C). 20 and 19 will become 18 (R) and 17 (Q) respectively.
