Directions:(1-4) Study the following information carefully and answer the questions given below.
H 4 7 $ 2 P W 5 E M % @ 8 # 3 A J & U G R 6 4 * ? B 9 T

1. How many such consonants are there each of which is immediately preceded by a letter and immediately followed by a symbol?


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?

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 /

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 10th element to the right of the 12th element to the left of the 16th 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)
16th element from the right → !
12th element to the left of ‘!’ → 6
10th element to the right of ‘6’ → 7
So, 10th element to the right of the 12th element to the left of the 16th 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 /

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.

    Having read this I thought it was very informative. I appreciate you taking the time and effort to put this article together. I once again find myself spending way to much time both reading and commenting. But so what, it was still worth it!
