Q2. Ans: The numbers given in the output are shifted one position to their right cyclically in the output. In Step I, the first number in the input has interchanged its position with the second number. In Step II, the third number has interchanged its position with the first number. In Step III, the fourth number has interchanged its position with the first number. This is followed in the steps further, till all the numbers are arranged by shifting by one place to the right cyclically.
6. Ans:d
Input : 38 14 56 12 92 39 114 43
Step I : 14 38 56 12 92 39 114 43
Step II : 56 38 14 12 92 39 114 43
Step III : 12 38 14 56 92 39 114 43
Step IV : 92 38 14 56 12 39 114 43
Step V : 39 38 14 56 12 92 114 43
Step VI : 114 38 14 56 12 92 39 43
Step VII : 43 38 14 56 12 92 39 114
Step VII is the final output.
7. Ans:a
In each step, only one element is rearranged. Hence the total number of steps we require to get the
final output is (n-1),where ’n’ is the total number of elements in the input.
In this input, the total number of elements = 7
Hence we require (7-1) = 6 steps to get the final output.
8. Ans:d
In the output the numbers given in the input are rearranged by shifting each number by one position to
the right cyclically. Hence, to get the input from the output the converse logic has to be applied, ie,
the numbers should be shifted to their left by one place. Hence, the input is 94 32 51 87 13 7 23
58.
9. Ans:c
It is given that the first eight prime numbers are taken in ascending order as the input. Hence, the
input and output will be as follows.
Input : 2 3 5 7 11 13 17 19
Step I : 3 2 5 7 11 13 17 19
Step II : 5 2 3 7 11 13 17 19
Step III : 7 2 3 5 11 13 17 19
Step IV : 11 2 3 5 7 13 17 19
10. Ans:e
The given input is
Input : 256 159 386 125 81 64 121
Step I : 159 256 386 125 81 64 121
Step II : 386 256 159 125 81 64 121
Step III : 125 256 159 386 81 64 121
Step IV : 81 256 159 386 125 64 121
Step V : 64 256 159 386 125 81 121
Step VI : 121 256 159 386 125 81 64
Hence, the last but one step is Step V.
