Logical Reasoning Test - 21

Reverse alphabet series,

Z Y X W V U T S R Q P O N M L K J I H G F E D C B A    

12th letter from the left → O

8th to the right of the "O" → G

Hence, the correct answer is "G".

Given word:  'STARTEW'

So, there are two such pairs i.e. ST and RT.

Hence, the correct answer is "Two".

Mistake Points

Here, in both forward and backward directions, means that in the given word we can make pairs in both forward and backward directions.

Thus, only S → T in the forward direction and R → T in the backward direction are possible cases.

Alphabet series ranges from A to Z, and there it stops. So, we can't apply the rule on W and A, as after Z, the series ends.

[Consider the example of LINEAR ARRANGEMENT of A to Z in a line and NOT CIRCULAR ARRANGEMENT]

The logic followed here is:-

Given series: L K A ? Z 6 N T $ * I ^ J # B β U C D 9 Z Y P © 3 ¥ 5 M G E F

If we have a combination of the same directions like left and left or right and right then we take the difference of the numbers to find the final position.

Here, 12th to the left of the 20th from the left end is given.

Therefore, 20 - 12 = 8

Hence, the 8^th element from the left end will be the answer to the given question.

L K A ? Z 6 N T $ * I ^ J # B β U C D 9 Z Y P © 3 ¥ 5 M G E F

Hence, the correct answer is T.

Alternate Method

The logic followed here is:-

Given series: L K A ? Z 6 N T $ * I ^ J # B β U C D 9 Z Y P © 3 ¥ 5 M G E F

The 20^th element from the left end is 9

The 12th element to the left of 9 is T

L K A ? Z 6 N T $ * I ^ J # B β U C D 9 Z Y P © 3 ¥ 5 M G E F

Hence, the correct answer is T.

Important Points

The logic behind the given directions is as follows:

1. If the same directions are given in the question

like, left and left or right and right then take a difference of the numbers.

2. If the opposite directions are given in the question

like, left and right or right and left then take a sum of the numbers.

Given word : ETHICAL

According to the question :

1) Each vowel is changed to the following letter in the English alphabetical series

⇒ Vowels is the word 'ETHICAL' :- 

Here, the transformation will be "FTHJCBL"

2) Each consonant is changed to the previous letter in the English alphabetical series

⇒ Consonants is the word 'ETHICAL' :- 

Here, the transformation will be "FSGJBBK"

Thus, according to the final arrangement, "FSGJBBK" there are three alphabets i.e H, I and J between the alphabet which is 3rd from the left  i.e 'G' and 1st from the right is 'K' according to English alphabetical series.

Hence, "Three" is the correct answer.

Second element in every pair is third to the right of first element except 27.

6 6 8 5 5 3 7 3 7 2 5 9 8 7 8 1 5 5 4

There is a gap of two digits in every number like, there are 5 and 5 between 8 and 3 in 83.

Similarly, there are 7 and 2 between 3 and 5 in 35 and 7 and 8 between 8 and 1 in 81. But there are 5, 8, 8, and 7 between 2 and 7 in 27.

Hence, 27 does not belong to the group.

According to the given information,

Number should come before a letter , but not after a symbol.

Not symbol → Number → Letter

P n 4 # 3 a 2 Q r 6 4 N d $ e # f 6 g 9 h u z 7 c h I $ 5 x u 4 #

Number of times the condition satisfied is :

[a 2 Q] , [6 4 N] , [f 6 g] , [g 9 h] , [z 7 c]

Hence, “5” is the correct answer.

Given series: P M S K Q A B M N O P Q R W

1) Letters at even positions: M, K, A, M, O, Q, W

Succeeding letters: N, L, B, N, P, R, X

2) Letters at odd positions: P, S, Q, B, N, P, R

Preceding Letters: O, R, P, A, M, O, Q

New series: O, N, R, L, P, B, A, N, M, P, O, R, Q, X

Letters appearing twice in the new series: O, N, R and P

Hence, the answer is option 3.

The 3^rd, 5^th, 6^th and the last letters of the word EVENTFUL are E, T, F, and L.

The four letter meaningful words that can be made from the letters E, T, F, and L are FELT and LEFT.

There are two four letter meaningful words possible using the given letters.

Therefore, two is the correct answer.

The logic followed here is:

• Vowels are a, e. i, o, u.
• Consonants are all the letters in English alphabet except vowels.

In the given series, consonants that are immediately followed by a vowel are:

Series : (Left) A T G H @ 7 D O G K I 7 # P E 4 1 D & G O H 4 @ 3 1 K M B U C D (Right)

 Thus, there are five consonants that are immediately followed by a vowel, namely DO, KI, PE, GO, BU.

Hence, 5 is the correct answer.

The given letter clusters are,

AIN, ONK, AST, EJO

When each letter is changed to the next letter in the English alphabetical order, the words formed are

BJO, POL, BTU, FKP

From the above words, only one word doesn't have a vowel.

Hence, the correct answer is option 4).
