Q: A E C B % 7 D $ E B 5 C ? 3 D E 9 @ 2 #  If all the vowels are dropped from the above arrangement which of the following will be the twelth from the left end of the above arrangement?
A.  3
B.  @
C. D
D. 9
Solution: After dropping  vowels we have the following arrangement: C B % 7 D $ B 5 C ? 3 D 9 @ 2 #
Hence, D is twelfth from the left end of the above arrangement.
The correct answer is: C) D
Q: 7 is to 34 as 5 is to
A.  33
B.  24
C.  54
D. 41
Solution: We can get this by any of two explanations.  
Answer 1: 41 7 = 3 + 4  = 34
Similarly, 5 = 4 + 1  = 41  
 Answer 2 :  41 7 - 3 = 4  => 34
Similarly, 5 - 4 = 1  => 41
The correct answer is: D) 41
Q: C L R T B Q S M A P D I  N F J K G Y X Four of the following  five are alike in a certain way and so form group. Which is the one that does not belong to the group? 1. LBT     2.IJF    3. PID    4. BMS
A.  BMS
B.  LBT
C. IJF
D. PID
Solution: L→+3B→-1T  I→+3J→-1F  P→+2I→-1D  B→+3→-1S   Therefore, PID is not in the form of other patterns.    
The correct answer is: D) PID
Q: 8, 15, 28, 53, ?, 199
A. 101
B.  102
C. 103
D.  104
Solution: Here the series of the form is x2 - 1, x2 - 2, x2 - 3,...  53 x 2 - 4 = 106 - 4 = 102
The correct answer is: B) 102
Q: A is the brother of B. B is the brother of C. D is the father of A. Based on these three statements, which of the following statements cannot be definitely true ?
A.  B is the brother of A.
B.  B is the son of D.
C.  A is the brother of C.
D. C is the brother of A.
Solution: A is the brother of B and B is the brother of C. So, C may be the brother or sister of A.   
The correct answer is: D) C is the brother of A.
Q: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z   Which letter is in the middle between the ninth letter from the right and eighth letter from the left in the given alphabets?
A.  N
B. O
C.  L
D.  M
Solution: 9th letter from the right means (26 - 9 + 1 =) 18th letter from the left. Now, the middle letter between 18th letter from the left  and 8th letter from the left = [(18+8)/2] = 13th leter from the left = M.
The correct answer is: D) M
Q: In a row of boys, If A who is 10th from the left and B who is 9th from the right interchange their positions, A becomes 15th from the left. How many boys are there in the row ?
A.  23
B.  31
C.  27
D.  28
Solution: Clearly, A’s new position is 15th from the left. But this is the same as B’s earlier position which is 9th from the right.  
The correct answer is: A) 23
Q: 583 is related to 293 in the same way as 488 is related to____
A. 291
B.  378
C.  487
D.  581
Solution: Sum of digits of the first number is 2 more than the sum of digits of the second number.
The correct answer is: B) 378
Q: Find the wrong number in the given series. 8, 27, 125, 343, 1381
A.  27
B. 8
C.  343
D. 1381
Solution: Given series follows Cubes on Prime Numbers   
i.e 23, 33, 53,...but  93 is 1331  
so 1381 is wrong
The correct answer is: D) 1381
