Solutions

S1. Ans. (d)
Sol. Given series – 3 6 < 5 @ 2 # 4 1 > 3 & 7 8 ] 5 \$ 9 ! 4 6 % 8 5 { 2 7 } 8 +
Hence, there are six symbols which are immediately preceded by a prime number.

S2. Ans. (b)
Sol. Given series – 3 6 < 5 @ 2 # 4 1 > 3 & 7 8 ] 5 \$ 9 ! 4 6 % 8 5 { 2 7 } 8 +
8th symbol form the left end – !
So, 6th to the right of ! – {

S3. Ans. (e)
Sol. Given series – 3 6 < 5 @ 2 # 4 1 > 3 & 7 8 ] 5 \$ 9 ! 4 6 % 8 5 { 2 7 } 8 +
So, required sum – 2 + 4 + 1 + 3 + 7 + 8 + 5 + 9 = 39

S4. Ans. (c)
Sol. Given series – 3 6 < 5 @ 2 # 4 1 > 3 & 7 8 ] 5 \$ 9 ! 4 6 % 8 5 { 2 7 } 8 +
After dropping – 6 < @ 2 # 4 > & 8 ] \$ ! 4 6 % 8 { 2 } 8 +
4th number from the right end – 6
So, 5th to the left of 6 – 8

S5. Ans. (c)
Sol. Given series – 3 6 < 5 @ 2 # 4 1 > 3 & 7 8 ] 5 \$ 9 ! 4 6 % 8 5 { 2 7 } 8 +
Hence, there are three numbers which are immediately preceded by an even number.

Solution (6-10):
Sol. In Step 1: The first three digits in all the numbers from the left end, are written in reverse order with in the number. No change is made to the remaining digits.
Ex-(64533) will be arranged as (54633).
In Step II: The numbers are arranged in descending order from extreme left end (according to the sum of the digits). (Number with the highest sum of digits will be arranged at extreme left end and the number with the 2nd highest sum of digits will be arranged after the 1st number and so on).
In Step III: The product of 1st and last digit from the left end of the number is written (from the left end) at the starting of each number, followed by the remaining digits in the same sequence to form a five-digit number. Ex- (85794) will be arranged as (32579).
(8 × 4) = 32, and (579) will be written in same sequence, so (32579).
In Step IV: The sum of first three digits from the left end is written at the left end of each number within the number, followed by remaining digits in the same sequence to form a four-digit number. Ex- (32579) will be arranged as (1079).
(3+2+5) = 10, and (79) will be written in same sequence, so (1079).
In Step V: All the numbers are arranged in ascending order from the extreme left end.
In Step VI: All the digits of each number are arranged in descending order within the number.

S10. Ans. (a)

Solution (11-15):
Sol. One number and one word is arranged in each step.
In the arrangement, numbers are arranged according to the increasing order of the sum of two-digit number from left end in each step.
Words are arranged as per its first letter (followed by second letter if first letter is same) from the right end in every step. First vowel and then consonant as they appear in alphabet series.

Input: 68 won appear 76 those now alone 66 52 is 92
Step I: 52 68 won appear 76 those now 66 is 92 alone
Step II: 92 52 68 won 76 those now 66 is alone appear
Step III: 66 92 52 68 won 76 those now alone appear is
Step IV: 76 66 92 52 68 won those alone appear is now
Step V: 68 76 66 92 52 won alone appear is now those
Step VI: 68 76 66 92 52 alone appear is now those won
