Answers & Solutions:
1) Answer (C)
As we can see in the 1st step the smallest number come to the 1st position from left.
In the 2nd step the largest number comes to the 2nd position from left.
In the 3rd step the 2nd smallest number come to the 3rd position from left and so on.
Thus, 64 326 187 87 118 432 219 348
Step 1:- 64 432 326 187 87 118 219 348
Step 2:- 64 432 87 326 187 118 219 348

3) Answer (C)
4) Answer (A)
5) Answer (C)
Divide the whole sequence into group of words of 4, 2 and 4 so in the input the-
First group will be– Smile Nile Style Mile
Second group will be – Shine Wine
Third group will be – Mine Swine Bovine Feline
In step 1 the 1 and 2 of Third group are exchanging their position with the 3 and 4 respectively i.e. Mine Swine are exchanging their position with Bovine Feline respectively with everything else constant
therefore step 1 is- Smile Nile Style Mile Shine Wine Bovine Feline Mine Swine
In step 2 the 1 and 2 of First group are exchanging their position with the 3 and 4 respectively i.e. Smile Nile are exchanging their position with Style Mile respectively with everything else constant
therefore step 2 is- Style Mile Smile Nile Shine Wine Bovine Feline Mine Swine
In step 3 the 1 and 2 of Second group are exchanging their position i.e. Shine is exchanging it’s position with Wine with everything else constant
therefore step 3 is- Style Mile Smile Nile Wine Shine Bovine Feline Mine Swine
In step 4 the 1 and 2 of First group are exchanging their position i.e. Style is exchanging it’s position with Mile , 3 and 4 of First group are exchanging their position i.e. Smile is exchanging it’s position with Nile and Similarly the 1 and 2 of Third group are exchanging their position i.e. Bovine is exchanging it’s position with Feline , 3 and 4 of Third group are exchanging their position i.e. Mine is exchanging it’s position with Swine with the positions of Shine and Wine remaining same
therefor step 4 is- Mile Style Nile Smile Wine Shine Feline Bovine Swine Mine
In step 5 the 1 and 2 of First group are exchanging their position with the 3 and 4 respectively i.e. Mile Style are exchanging their position with Nile Smile respectively and the 1 and 2 of Third group are exchanging their position with the 3 and 4 respectively i.e. Feline Bovine are exchanging their position with Swine Mine respectively with everything else constant
therefor step 5 is- Nile Smile Mile Style Wine Shine Swine Mine Feline Bovine
In step 6 the 1 and 2 of Third group are exchanging their position with the 3 and 4 respectively i.e. Swine Mine are exchanging their position with Feline Bovine respectively with everything else constant
therefor step 6 is- Nile Smile Mile Style Wine Shine Feline Bovine Swine Mine
In step 7 the 1 and 2 of First group are exchanging their position with the 3 and 4 respectively i.e. Nile Smile are exchanging their position with Mile Style respectively with everything else constant
therefor step 7 is- Mile Style Nile Smile Wine Shine Feline Bovine Swine Mine
As can be observed the pattern is repeating
therefore step 8 will be Mile Style Nile Smile Shine Wine Feline Bovine Swine Mine
step 9- Style Mile Smile Nile Shine Wine Bovine Feline Mine Swine
step 10- Smile Nile Style Mile Shine Wine Mine Swine Bovine Feline
step 11- Smile Nile Style Mile Shine Wine Bovine Feline Mine Swine
step 12- Style Mile Smile Nile Shine Wine Bovine Feline Mine Swine

Divide the whole sequence into group of words of 4, 2 and 4 so in the input the-
First group will be– Smile Nile Style Mile
Second group will be – Shine Wine
Third group will be – Mine Swine Bovine Feline
In step 1 the 1 and 2 of Third group are exchanging their position with the 3 and 4 respectively i.e. Mine Swine are exchanging their position with Bovine Feline respectively with everything else constant
therefore step 1 is- Smile Nile Style Mile Shine Wine Bovine Feline Mine Swine
In step 2 the 1 and 2 of First group are exchanging their position with the 3 and 4 respectively i.e. Smile Nile are exchanging their position with Style Mile respectively with everything else constant
therefore step 2 is- Style Mile Smile Nile Shine Wine Bovine Feline Mine Swine
In step 3 the 1 and 2 of Second group are exchanging their position i.e. Shine is exchanging it’s position with Wine with everything else constant
therefore step 3 is- Style Mile Smile Nile Wine Shine Bovine Feline Mine Swine
In step 4 the 1 and 2 of First group are exchanging their position i.e. Style is exchanging it’s position with Mile , 3 and 4 of First group are exchanging their position i.e. Smile is exchanging it’s position with Nile and Similarly the 1 and 2 of Third group are exchanging their position i.e. Bovine is exchanging it’s position with Feline , 3 and 4 of Third group are exchanging their position i.e. Mine is exchanging it’s position with Swine with the positions of Shine and Wine remaining same
therefor step 4 is- Mile Style Nile Smile Wine Shine Feline Bovine Swine Mine
In step 5 the 1 and 2 of First group are exchanging their position with the 3 and 4 respectively i.e. Mile Style are exchanging their position with Nile Smile respectively and the 1 and 2 of Third group are exchanging their position with the 3 and 4 respectively i.e. Feline Bovine are exchanging their position with Swine Mine respectively with everything else constant
therefor step 5 is- Nile Smile Mile Style Wine Shine Swine Mine Feline Bovine
In step 6 the 1 and 2 of Third group are exchanging their position with the 3 and 4 respectively i.e. Swine Mine are exchanging their position with Feline Bovine respectively with everything else constant
therefor step 6 is- Nile Smile Mile Style Wine Shine Feline Bovine Swine Mine
In step 7 the 1 and 2 of First group are exchanging their position with the 3 and 4 respectively i.e. Nile Smile are exchanging their position with Mile Style respectively with everything else constant
therefor step 7 is- Mile Style Nile Smile Wine Shine Feline Bovine Swine Mine
As can be observed the pattern is repeating
therefore step 8 will be Mile Style Nile Smile Shine Wine Feline Bovine Swine Mine
step 9- Style Mile Smile Nile Shine Wine Bovine Feline Mine Swine

8) Answer (A)
The machine is arranging the numbers in the increasing order of the sum of the digits on the number.
Input: 245 (11), 316 (10), 436 (13), 519 (15), 868 (22), 710 (8), 689 (23).
The number in the bracket indicates the sum of digits of the given number.
Step 1: 710 (8), 316 (10), 436 (13), 519 (15), 868 (22), 245 (11), 689 (23).
∴ The machine has swapped 710 (8) with 245 (11).
Step 2: 710 (8), 316 (10), 245 (11), 519 (15), 868 (22), 436 (13), 689 (23).
Thus it has swapped 436 (13) with 245 (11).
Step 3: 710 (8), 316 (10), 245 (11), 436 (13), 868 (22), 519 (15), 689 (23).
Thus it has swapped 436 (13) with 519 (15).
Step 4: 710 (8), 316 (10), 245 (11), 436 (13), 519 (15), 868 (22), 689 (23).
Thus it has swapped 519 (15) with 868 (22).
Going by the logic mentioned above,
Input: 655 (16), 436 (13), 764 (17), 799 (25), 977 (23), 572 (14), 333 (9).
Step 1: 333 (9), 436 (13), 764 (17), 799 (25), 977 (23), 572 (14), 655 (16).
Step 2: 333 (9), 436 (13), 572 (14), 799 (25), 977 (23), 764 (17), 655 (16).
Step 3: 333 (9), 436 (13), 572 (14), 655 (16), 977 (23), 764 (17), 799 (25).
This is the required sequence which is achieved in Step 3.
Hence, option A is the correct answer.
9) Answer (B)
10) Answer (D)
The machine is arranging the numbers in the increasing order of the sum of the digits on the number.
Input: 245 (11), 316 (10), 436 (13), 519 (15), 868 (22), 710 (8), 689 (23).
The number in the bracket indicates the sum of digits of the given number.
Step 1: 710 (8), 316 (10), 436 (13), 519 (15), 868 (22), 245 (11), 689 (23).
∴ The machine has swapped 710 (8) with 245 (11).
Step 2: 710 (8), 316 (10), 245 (11), 519 (15), 868 (22), 436 (13), 689 (23).
Thus it has swapped 436 (13) with 245 (11).
Step 3: 710 (8), 316 (10), 245 (11), 436 (13), 868 (22), 519 (15), 689 (23).
Thus it has swapped 436 (13) with 519 (15).
Step 4: 710 (8), 316 (10), 245 (11), 436 (13), 519 (15), 868 (22), 689 (23).
Thus it has swapped 519 (15) with 868 (22).
We are given the result obtained in step 3rd. We can’t go backward as there is no logic for processing backward. Hence, option D is the correct answer.
