Sequential Output Tracing Questions and Answers

Answer: D

Correct answer: None of these

The arrangement this question refers to is not reproduced with the item as it now stands, so the seating cannot be reconstructed here. What the key establishes is that Q’s two immediate neighbours are not the pair P and T, nor P and B, nor P and D - at least one of Q’s neighbours is someone other than P, or the partner is not among T, B and D. Since none of the three offered pairs is correct, the answer is none of these.

Answer: C

Correct answer: C is to the immediate right of B

The arrangement these questions were set against is not reproduced with the item as it now stands. What can be said is that this statement is the one the information fixes completely, while the other three are not determined - they may hold in some arrangements consistent with the clues and not in others, and “definitely true” requires that a statement hold in every arrangement the clues permit. The companion question in this set is keyed to the same relation, B followed immediately by C.

Answer: D

Correct answer: 762

Every term is 4 more than the last and the first is \( -20 \), so every term is a multiple of 4. Testing the options: \( 220 = 4\times55 \), \( 440 = 4\times110 \) and \( 668 = 4\times167 \) all qualify, but \( 762 = 4\times190.5 \) does not. It is even, which is what makes it look plausible, but divisibility by 4 is the test - and the last two digits, 62, are not a multiple of 4.

Answer: B

Start constructing the sequence until you see the pattern
1...5...(average of 1 and 5 = 3)...(average of 1, 5, and 3 = 3)...(average of 1,5,3 and 3 = 3)
now you can see that all subsequent terms will be 3

Answer: C

Given number of girls are twice that of boys.
\small \Rightarrow G=2B and G+B = 60
\small \Rightarrow  G=40 and B= 20
Given Laxmi ranked 27th from the top and 9 boys are ahead of Laxmi.
\small \therefore There are 17 girls ahead of Laxmi.
\small \therefore Number of girls who ranked after Laxmi = 40 - (17+1) = 22.

Answer: C

Obsrving the given arrangement, we find the following pattern:
If we arrange the words in the given input in the alphabetical order and then label them as 1,2,3,4,5,6, then the last step contains the words in the order 6,1,5,2,4,3. However, the position of only one word is alteredat each step.
Input:car on star quick demand fat
Step1: star car on quick demand fat
Step2: star car quick on demand fat
Step3: star car quick demand on fat
Hence, the answer is C.

Answer: A

Carefully obsrving the given arrangement, we find the following pattern:
We observe that,first all the words with the highest number of letters are arranged in the alphabetical order, followed by the words with the second highest number of letters and so on.However, the position of only one word is altered at each step.
Input: more fight cats cough sough acts idea
Step1: cough more fight cats sough acts idea
Step2: cough fight more cats sough acts idea
Step3: cough fight sough more cats acts idea
Step4: cough fight sough acts more cats idea
Step5: cough fight sough acts cats more idea
Step6: cough fight sough acts cats idea more
 
Hence, the answer is A

Answer: B

Carefully obsrving the given arrangement, we find the following pattern:
We observe that the given numbers are arranged in descending order (from left to right), altering the position of only one number in each step, followed by the other numbers as it is. The process continues till the whole set of numbers is arranged in the descending order.
Step1: 28 16 09 24 15 04
Step2: 28 24 16 09 15 04
Step3: 28 24 16 15 09 04
Hence, the answer is B

Answer: C

Answer: D

Input : Together over series on feast the so
Step I: feast Together over series on the so
Step II: feast on Together over series the so
Step III: feast on over Together series the so
Step IV: feast on over series Together the so 
Step V: feast on over series so Together the
Step VI: feast on over series so the Together
Clearly step VI is the last step and step V is the last but one (second last)
