Ans:3
H 4 7 $ 2 P W 5 E M % @ 8 # 3 A J & U G R 6 4 * ? B 9 T

2. If all the symbols are removed from the above arrangement, then what will be the thirteenth element from the right end?
H 4 7 $ 2 P W 5 E M % @ 8 # 3 A J & U G R 6 4 * ? B 9 T

Ans:1
H 4 7 2 P W 5 E M 8 3 A J U G R 6 4 B 9 T

3. If first element is interchanged with the fifteenth element, second element is interchanged with the sixteenth element and so on till the last. Then, which of the following will be the fifth to the left of $?
H 4 7 $ 2 P W 5 E M % @ 8 # 3 A J & U G R 6 4 * ? B 9 T

Ans:4
3 A J & U G R 6 4 * ? B 9 T H 4 7 $ 2 P W 5 E M % @ 8 #

4. Four of the following five are alike in a certain way and hence form a group. Which of the following one that does not belong to the group?
H 4 7 $ 2 P W 5 E M % @ 8 # 3 A J & U G R 6 4 * ? B 9 T

Ans:3
% @ 8 # -> %#8
U G R 6 -> U6R
M % @ 8 -> M@8
W 5 E M -> WME
7 $ 2 P -> 7P2

Directions:(5-8) Study the following sequence carefully and answer the questions given below it.
A @ 6 # D H & % G K * M 7 9 ! ^ 2 P V J + 4 R E Y > C < F /

5. How many such digits are there which are immediately followed by a symbol but not immediately preceded by a symbol?

Two
Three
Four
One
None

Ans:4
Arrangement required: Symbol ≠ Digit → Symbol
Given series: A @ 6 # D H & % G K * M 7 9 ! ^ 2 P V J + 4 R E Y > C < F /
Clearly one such pair is there i.e. 7 9 !.

6. How many consonants are there which are neither immediately followed by a consonant nor immediately preceded by a symbol?
A @ 6 # D H & % G K * M 7 9 ! ^ 2 P V J + 4 R E Y > C < F /

Two
Three
None
Five
Four

Ans:4
Arrangement required: Symbol ≠ Consonants ≠ Consonants
Given series: A @ 6 # D H & % G K * M 7 9 ! ^ 2 P V J + 4 R E Y > C < F /
Clearly there are five such pairs i.e. D H &, G K *, V J +, 4 R E, E Y >

7. Which is the 10^th element to the right of the 12^th element to the left of the 16^th element from the right end?
A @ 6 # D H & % G K * M 7 9 ! ^ 2 P V J + 4 R E Y > C < F /

Ans:3
Given series: (Left) A @ 6 # D H & % G K * M 7 9 ! ^ 2 P V J + 4 R E Y > C < F / (Right)
16^th element from the right → !
12^th element to the left of ‘!’ → 6
10^th element to the right of ‘6’ → 7
So, 10^th element to the right of the 12^th element to the left of the 16^th element from the right is 7.

8. How many such symbols are there which are immediately followed by a consonant and immediately preceded by a digit?
A @ 6 # D H & % G K * M 7 9 ! ^ 2 P V J + 4 R E Y > C < F /

Three
Two
Four
None
One

Ans:5
Arrangement required: Digit → Symbols → Consonant
Given series: A @ 6 # D H & % G K * M 7 9 ! ^ 2 P V J + 4 R E Y > C < F /
Clearly one such pair is there i.e. 6 # D.
