Directions : Read the following questions carefully and choose the right answer.
1
Each consonant of the word ‘TERMINATION’ is changed to the previous letter in the English alphabetical series and each vowel is changed to the next letter in the English alphabetical series. If the new alphabets thus formed are arranged in alphabetical order (from left to right), which of the following will be the sixth letter from the right end?
» Explain it
A
The given word:

T  E  R  M  I  N  A  T   I  O  N

Applying the above condition, we have new word:

S  F  Q  L  J  M  B  S  J  P  M

Now, arranging in alphabetical order (from left to right)

B  F J  J  L  M  M  P  Q  S  S

Hence, M is sixth from the right.

Hence, the correct answer is option A.
 
2
If in the word SEPTUAGENARIAN first three and then next three letters are written in reverse order and the rest of the letters are written as they appear in English alphabet, the positions of how many letters get changed in the new arrangement?
» Explain it
D
S E P T U A G E N A R I A N
P E S A U T A A E G I N N R
 
Clearly, except E and U the positions of all other letters (12) get changed in the new arrangement.

Option D is hence the correct answer.
 
3
If all the letters of the word INTROSPECTION are arranged in a way that all the vowels are arranged in the beginning in alphabetical order and then all the consonants are arranged in the alphabetical order, then position of how many letters remains unchanged?
» Explain it
B
Given word and the new word after the given rearrangement:
 
I N T R O S P E C T I O N
E I I O O C N N P R S T T
 
Thus position of only one letter i.e, "O" remains unchanged.

Hence option B is correct.
 
4
In the word 'DOORSTEP' if all the vowels are replaced with the letter immediate next to it in the english alphabet series and all the consonants are replaced with the letter immediate before it in the english alphabet series, then how many vowels are there in the new word so formed?
» Explain it
B
Given word and the new word after the given rearrangement:
 
D O O R S T E P
C P P Q R S F O
 
Thus 'O' is the only vowel in the new arrangement.

Hence option B is correct.
 
5
If all the vowels of the word 'FRAGMENT' are changed to the letter immediately succeeding them in the english alphabet series and all the consonants are changed to the letter immediately preceding them in the english alphabet series, then how many letters of the new word are similar to the letters of the old word?
» Explain it
C
Old word F R A G M E N T
New word E Q B F L F M S

Apparently, four letters viz. E, F, F and M of the new word are similar to the letters of the old word.

Hence option C is the correct answer.
