Answers & Solutions:
1) Answer (E)
J * R 3 P L 2 # I N 7 O C @ K 5 D = M $ 6 B < A Q 4
The pattern followed is : the third letter is to the immediate right of first letter and the middle letter is 3rd to the left of first letter.
Similar pattern is observed in all the options except B $ < where the middle letter is second to the left of first letter.
=> Ans – (E)
2) Answer (A)
Series : P R J , # L 3 , 7 I 2 , @ O N , ?
PRJ : R is second to the left of P and J is second to the left of R.
For the next sequence that start with ‘#’, we go third to the left of first letter of previous sequence.
#L3 : L is second to the left of # and 3 is second to the left of L.
Now, again we go 3rd to the right of # and the next sequence will start with 7.
Similarly, after @ON, the next sequence = D K C
=> Ans – (A)
3) Answer (C)
J * R 3 P L 2 # I N 7 O C @ K 5 D = M $ 6 B < A Q 4
If the above series is re-arranged in the reverse order, series :
4 Q A < B 6 $ M = D 5 K @ C O 7 N I # 2 L P 3 R * J
16th element from left end = 7
11th element to the left of 7 = B
=> Ans – (C)
Method II : Instead of reversing the sequence, we can reverse the direction in question, i.e. we have to find 11th element to the right of 16th element from right end of the original series, answer will come out to B.
4) Answer (D)
Numbers which are immediately preceded by a consonant and not immediately followed by a symbol.
Such numbers are : J * R 3 P L 2 # I N 7 O C @ K 5 D = M $ 6 B < A Q 4
Thus there are 3 such numbers.
=> Ans – (D)
5) Answer (E)
Symbols which are immediately preceded by a number and immediately followed by a consonant.
Thus, we need to find : (number) (symbol) (consonant)
There is no such sequence in the given series.
=> Ans – (E) : none of these
6) Answer (A)
H T 7 L E $ 2 Y # W 4 I F @ V 3 A 8 % K 1 M 0 5 G U 6 C
14th element from left end = @
5th to the left of @ = #
=> Ans – (A)
7) Answer (C)
Pairs of vowels which are immediately preceded by a number but not Immediately followed by a symbol
Thus, we need to find : (number) (vowel)
H T 7 L E $ 2 Y # W 4 I F @ V 3 A 8 % K 1 M 0 5 G U 6 C
There are only 2 such vowels.
=> Ans – (C)
8) Answer (E)
H T 7 L E $ 2 Y # W 4 I F @ V 3 A 8 % K 1 M 0 5 G U 6 C
H E 7 : The pattern is that the middle letter is second to the right of last letter, and the first letter is second to the left of last letter.
Similar pattern is observed in 24# , K5M , 3K8 but not in FVA.
=> Ans – (E)
9) Answer (B)
Number of consonants which are immediately preceded by a number and also immediately followed by a symbol,
Thus, we need to find : (number) (consonant) (symbol)
H T 7 L E $ 2 Y # W 4 I F @ V 3 A 8 % K 1 M 0 5 G U 6 C
There is only 1 such consonant.
=> Ans – (B)
10) Answer (D)
Series : T 7 E , Y#4 , @VA ?
T 7 E : The middle letter is to the immediate right of first letter and the third letter is second to the right of middle letter.
Then the first letter of second sequence is third to the right of third letter of previous sequence.
Y # 4 : # is to the immediate right of Y and 4 is second to the right of #.
Thus, after @ V A, next sequence = K 1 0
=> Ans – (D)
11) Answer (C)
Consonants which are immediately preceded by a consonant and immediately followed by a number
Thus, we need to find : (consonant) (consonant) (number)
7 R E T 4 A 9 % D F 1 U # B @ 8 H I © W M * 3 2 V $ 5 N P 6 Q
Thus, there are 2 such consonants.
=> Ans – (C)
12) Answer (D)
Numbers which are immediately preceded by a letter but not immediately followed by a symbol
Thus, we need to find : (letter) (number) (not symbol)
7 R E T 4 A 9 % D F 1 U # B @ 8 H I © W M * 3 2 V $ 5 N P 6 Q
Thus, there are 3 such cases.
=> Ans – (D)
13) Answer (C)
Vowels which are immediately followed by a symbol
Thus, we need to find : (vowel) (symbol)
7 R E T 4 A 9 % D F 1 U # B @ 8 H I © W M * 3 2 V $ 5 N P 6 Q
There are only 2 such vowels.
=> Ans – (C)
14) Answer (B)
Series : 7 R E T 4 A 9 % D F 1 U # B @ 8 H I © W M * 3 2 V $ 5 N P 6 Q
RTA : The first letter is second to the left of middle letter and the third letter is second to the right of middle letter.
Similar pattern is followed in #@H , 3V5 , IW*
But in 9DF, F is immediate right of D, thus its the odd one out.
=> Ans – (B)
15) Answer (A)
Series : 7 R E T 4 A 9 % D F 1 U # B @ 8 H I © W M * 3 2 V $ 5 N P 6 Q
12th from left end = U
4th to the left of ‘U’ = %
=> Ans – (A)
