A) Nil      B) One     C) Two     D) Three     E) More than three

Solution: Given series:

2 D N ! P \$ V 4 Z 8 T α R @ 9 ~ X ? B 5 O I ( E 6

There is only one symbol " ( " that satisfies the given condition.

Ans: B

2. If all the vowels are dropped from the above series, which of the following would be the eighth element to the right of the thirteenth element from the left end ?

A) 6      B) 2      C) (     ( D) D     E) None of these

Solution: The new arrangement becomes:

2 D N ! P \$ V 4 Z 8 T α R @ 9 ~ X ? B 5 ( 6

In case of opposite directions we add the positions and calculate the resultant position of an element from the given end of the series.

8th element to the right of the 13th element from the left end means (8 + 13) = 21st element from the left end, i.e, (.

Ans: C

= number of symbols + numbers of numerals

= 7 + 6 = 13

Solution: Given series:

X 1 S ~ 6 K I ! 9 N V 4 O 7 C J 5 E % 7 G R 3 F H 4 A T Q

In case of the same directions we take the difference of the positions and calculate the resultant position of an element from the given end of the series.

∴ 7th to the right of the 18th from the right end means (18 − 7) = 11th from the right end, i.e, %.

Solution: Given series :

X 1 S ~ 6 K I ! 9 N V 4 O 7 C J 5 E % 7 G R 3 F H 4 A T Q

Such symbols in the new arrangement may be indicated as follows:

X 1 A ~ 6 K E ! 9 N V 4 O 7 C J 5 I % 7 G R 3 F H 4 S T Q There are three symbols (~, !, %) that satisfy the given condition.

Ans: D

9. If the order of the last fifteen elements is reversed, which of the following will be fifth to the right or twelfth from the left end ?

Solution: Given series :

X 1 S ~ 6 K I ! 9 N V 4 O 7 C J 5 E % 7 G R 3 F H 4 A T Q

The new arrangement is :

X 1 S ~ 6 K I ! 9 N V 4 O 7 Q T A 4 H F 3 R G 7 % E 5 C

In case of opposite directions we add the positions and calculate the resultant position of an element from the given end of the series.  5th to the right of 12th from the left end means (5 + 12) = 17th from the left end, i.e., A

Ans: A

Solution: In all other groups, the first and second elements move 2 steps backward and 4 steps forward respectively to give the second and third elements.

Ans: C

Directions (Qs. 11 - 15): These questions are based on the following arrangement of symbols, letters and numbers:

14. Total number of pairs of adjacent symbol and letter (X), total number of pairs of adjacent letter and number (Y) and total number of pairs of adjacent number and symbol (Z) in the above arrangement are written in the descending order. Which of the following will indicate the same ?

A) X, Y, Z     B) X, Z, Y       C) Y, X, Z      D) All the three are equal in number    E) None of these

Solution:  Adjacent symbol-letters pairs are δ M, @ Z, ÷ F, β J. So, X = 4.

Adjacent letter-numbers pairs are M 5, I 8, G 2, J 9. So, Y = 4.

Adjacent number-symbol pairs are 5 @, 6 ∗, 2 β, 9 . So, Z = 4.

Thus, X = Y = Z.

Solution: In case of opposite directions we add the positions and calculate the resultant position of an element from the given end of the series. ∴ 5th to the right of the 18th from the right end means (18 − 5) = 13th from the right end, i.e,

Ans: A

19. Which of the following is the fourth to the right or twelfth from the left end of the above arrangement?
