Instruction for Q.1 to Q.3:
Study the following alphanumeric sequence carefully and answer the questions given
beside:
84 LAST 67 CRAB 78 NEWS 89 ROSE 76 UNDO
Q.1) If the digits attached to the word (left) that is starting with consonant and ending at a
consonant are to be multiplied within the number while the digits of the rest words are to
be added within the number then the words are arranged according to ascending order of
the number from left to right end then what would be the 11th letter from left end?
[a] A
[b] D
[c] S
[d] W
[e] T
Answer – (c)
Explanation:
We have the given sequence,
84 LAST 67 CRAB 78 NEWS 89 ROSE 76 UNDO
After, multiplying the digits of the word that is starting with consonant and ending at a
consonant and adding the digits of the rest words within the number, we get:
32 LAST 42 CRAB 56 NEWS 17 ROSE 13 UNDO
Arranging the series according to ascending order of the number from left to right end, we
get
13 UNDO 17 ROSE 32 LAST 42 CRAB 56 NEWS
Here, the 11th letter from left end is S.
Hence, the correct answer is option C.
Q.2) If all the letters which are attached to an odd number are reversed and all the letters
which are attached to an even number are changed to their succeeding letter then how
many letters in the new sequence will appear exactly twice?
[a] Two
[b] Three
[c] Four
[d] Five
[e] Seven
Answer – (d)
Explanation:
We have the given sequence,
84 LAST 67 CRAB 78 NEWS 89 ROSE 76 UNDO
After, reversing all the letters which are attached to an odd number and changing all the
letters which are attached to an even number to their succeeding letter, we get:
84 MBTU 67 XIZY 78 OFXT 89 ILHV 76 VOEP
Now, the letters in the new sequence appearing twice are T, X, I, V and O.
Hence, the correct answer is option D
Q.3) If a meaningful word is to be formed using the letters of words separately (using each
letter only once), given that the second letter of newly formed word must be a vowel then
what would be the total sum of the digits of the numbers attached to those words which
follow the condition given?
[a] 29
[b] 24
[c] 20
[d] 33
[e] 38
Answer – (a)
Explanation:
We have the given sequence,
84 LAST 67 CRAB 78 NEWS 89 ROSE 76 UNDO
Here, the meaningful words having second letter as a vowel that can be formed using the
above words separately are:
1 – ‘SALT’ using the word ‘LAST’
2 – ‘SORE’ using the word ‘ROSE’
Now, the number attached to the words ‘LAST’ and ‘ROSE’ are 84 and 89 respectively.
Required Sum = 8 + 4 + 8 + 9 = 29
Hence, the correct answer is option A.
