STEP 2 : 59 66 45 81 18 20 10 09 51 71
STEP 3 : 59 66 09 45 81 18 20 10 51 71
STEP 4 : 59 66 09 18 45 81 20 10 51 71
STEP 5 : 59 66 09 18 45 81 71 20 10 51
STEP 6 : 59 66 09 18 45 81 71 51 20 10

Question 1:

(a) 1st , 9th

( b) 4th , 1st 

(c) 3rd , 1st
d) 3rd , 8th 

(e)none of the following

Question 2:

This sequence is put in the same machine
48 , 74 , 86 , 98 , 09 , 29 . What would be the last number in the final sequence?
(a) 29 

(e) None of these

Question 3:

For the sequence in question (2 ) which number occupies position 4?
(a) 74 

(e) None of these.

Question 4:

How many steps are there in the output series in case of sequence in question (2)?
(a) 4 

(e) None of these

Question 5:

This sequence is put in the same machine
56 17 07 76 94 54 What would be the last number in the final sequence?
(a) 56 

ANSWERS:

(1) Here the two digits of the numbers are added and the number with the highest sum is placed first. For eg. 5+9 = 14 , 6+6 = 12 , therefore , 59 gets placed before 66.In case of equal sums , the one with smaller tens digit is placed first .
55 = 5+5 = 10 ; 7+8 = 15
Since 15 is higher than 14 i.e. (5+ 9) for 59 ; it would be placed first and 55 would be placed before 09 i.e. fourth position. Hence (b)

(2) INPUT : 48 74 86 98 09 29 

STEP 1 : 98 48 74 86 09 29
STEP 2 : 98 86 48 74 09 29
STEP 3 : 98 86 48 29 74 09
Therefore number 09 is placed last. Correct answer is (b)

(3) 4th position is occupied by 29.Hence (c)
(4) INPUT : 48 74 86 98 09 29
STEP 1 : 98 48 74 86 09 29
STEP 2 : 98 86 48 74 09 29
STEP 3 : 98 86 48 29 74 09
There are 3 steps. Hence (b)

(5) (d) 07 is the right answer
INPUT : 56 17 07 76 94 54
STEP 1: 76 56 17 07 94 54
STEP 2: 76 94 56 17 07 54
STEP 3 : 76 94 56 54 17 07
