NTS Analytical Reasoning Puzzles — Questions and Answers
Question 1: If all roses are flowers and some flowers fade quickly, which statement must be true?
- All roses fade quickly
- Some roses fade quickly
- No roses fade quickly
- Some roses may or may not fade quickly (Correct answer)
Correct answer: Some roses may or may not fade quickly
Since only 'some' flowers fade quickly and roses are flowers, we cannot determine whether roses specifically fade quickly or not.
This is a syllogism problem. 'All roses are flowers' means roses are a subset of flowers. 'Some flowers fade quickly' means at least one flower fades quickly, but we don't know which ones. Since we cannot determine if any of those quickly-fading flowers are roses, the only valid conclusion is that some roses may or may not fade quickly. NTS analytical reasoning tests logical deduction from given premises.
Question 2: In a row of children, Amir is 8th from the left and Sana is 12th from the right. If they exchange positions, Amir becomes 15th from the left. How many children are in the row?
- 22
- 24
- 26 (Correct answer)
- 28
Correct answer: 26
After exchange, Amir is at Sana's position (15th from left). Sana was 12th from right. Total = 15 + 12 - 1 = 26.
When Amir and Sana exchange positions, Amir moves to Sana's original spot. After exchange, Amir is 15th from the left, which was Sana's position. Originally, Sana was 12th from the right. Total children = position from left + position from right - 1 = 15 + 12 - 1 = 26. Linear arrangement problems are common in NTS analytical reasoning.
Question 3: If COMPUTER is coded as DPNQVUFS, how is LAPTOP coded?
- MBQUPQ (Correct answer)
- MBUUPQ
- MBQUPQ
- MBQUPR
Correct answer: MBQUPQ
Each letter is shifted by +1 in the alphabet: L→M, A→B, P→Q, T→U, O→P, P→Q = MBQUPQ.
Comparing COMPUTER to DPNQVUFS: C→D(+1), O→P(+1), M→N(+1), P→Q(+1), U→V(+1), T→U(+1), E→F(+1), R→S(+1). Each letter is shifted forward by 1. Applying the same rule to LAPTOP: L→M, A→B, P→Q, T→U, O→P, P→Q = MBQUPQ. Coding-decoding is a standard NTS analytical reasoning topic.
Question 4: Which number replaces the question mark? 3, 9, 27, 81, ?
- 162
- 216
- 243 (Correct answer)
- 324
Correct answer: 243
Each number is multiplied by 3: 3×3=9, 9×3=27, 27×3=81, 81×3=243.
This is a geometric sequence with a common ratio of 3. Each term is obtained by multiplying the previous term by 3: 3, 9, 27, 81, 243. The sequence represents powers of 3: 3¹, 3², 3³, 3⁴, 3⁵. Number pattern recognition is frequently assessed in NTS analytical reasoning sections.
Question 5: Five friends - Ali, Bilal, Cyrus, Danish, and Ehsan - are sitting in a circle. Ali is between Bilal and Ehsan. Cyrus is to the left of Bilal. Who is to the right of Ehsan?
- Ali
- Bilal
- Cyrus
- Danish (Correct answer)
Correct answer: Danish
Arrangement: Cyrus-Bilal-Ali-Ehsan-Danish (clockwise). Danish is to the right of Ehsan.
Start with Ali between Bilal and Ehsan. So the order around Ali is: Bilal-Ali-Ehsan. Cyrus is to the left of Bilal, placing Cyrus next to Bilal. The remaining person (Danish) fills the last spot next to Ehsan. Clockwise: Cyrus-Bilal-Ali-Ehsan-Danish. To the right of Ehsan is Danish. Circular seating arrangements are a classic NTS puzzle type.
Question 6: If Monday falls on the 1st of a month, what day will the 23rd of that month be?
- Monday
- Tuesday (Correct answer)
- Wednesday
- Thursday
Correct answer: Tuesday
From the 1st to the 23rd is 22 days. 22 ÷ 7 = 3 weeks + 1 day. So the 23rd is Tuesday.
If the 1st is Monday, we need to find the day for the 23rd. The difference is 23 - 1 = 22 days. Dividing by 7 (days in a week): 22 ÷ 7 = 3 remainder 1. So the 23rd falls 1 day after Monday, which is Tuesday. Calendar-based reasoning is a common NTS analytical question type.
Question 7: A clock shows 3:15. What is the angle between the hour and minute hands?
- 0°
- 7.5° (Correct answer)
- 15°
- 22.5°
Correct answer: 7.5°
At 3:15, the minute hand is at 90° (pointing at 3). The hour hand has moved 7.5° past the 3 o'clock position (15 min × 0.5°/min).
At 3:15, the minute hand points at 3 (90° from 12). The hour hand at exactly 3:00 would be at 90°, but by 3:15, it has moved further: 15 minutes × 0.5°/minute = 7.5° past the 3. So the hour hand is at 97.5° and the minute hand at 90°. The angle between them = 97.5° - 90° = 7.5°. Clock angle problems are a classic NTS analytical reasoning question.
Question 8: In a certain code, FISH is written as EHRG. How will DUCK be written?
- CTBJ (Correct answer)
- EVDL
- DTBK
- CUBJ
Correct answer: CTBJ
Each letter is shifted by -1: F→E, I→H, S→R, H→G. So D→C, U→T, C→B, K→J = CTBJ.
Analyzing the code: F→E(-1), I→H(-1), S→R(-1), H→G(-1). Each letter is replaced by the letter one position before it in the alphabet. Applying this to DUCK: D→C, U→T, C→B, K→J = CTBJ. Coding-decoding questions require identifying the transformation pattern and are staples of NTS analytical reasoning.
Question 9: If 'A' is the brother of 'B', 'B' is the sister of 'C', and 'C' is the father of 'D', how is 'A' related to 'D'?
- Father
- Uncle (Correct answer)
- Grandfather
- Brother
Correct answer: Uncle
B is C's sister, so B and C are siblings. A is B's brother, making A also C's sibling. C is D's father. So A is D's uncle.
Step by step: A is B's brother (A and B are siblings). B is C's sister (B and C are siblings). Therefore A and C are siblings. C is D's father. Since A is C's sibling, A is D's uncle. Blood relation problems require careful tracking of family connections and are frequently tested in NTS analytical reasoning.
Question 10: Complete the pattern: AZ, BY, CX, DW, ?
- EU
- EV (Correct answer)
- FV
- EX
Correct answer: EV
First letter goes forward (A,B,C,D,E) and second letter goes backward (Z,Y,X,W,V). Next is EV.
The pattern has two sequences: the first letter advances through the alphabet (A, B, C, D, E...) while the second letter goes backward (Z, Y, X, W, V...). Following this dual pattern, after DW comes EV. Pattern recognition with multiple simultaneous sequences is a common NTS analytical reasoning format.
Question 11: Six people P, Q, R, S, T, and U are standing in a queue. T is ahead of U but behind R. S is behind U. P is ahead of R. Q is just behind S. What is the order from front to back?
- P, R, T, U, S, Q (Correct answer)
- R, P, T, U, S, Q
- P, T, R, U, S, Q
- P, R, U, T, S, Q
Correct answer: P, R, T, U, S, Q
From the clues: P is ahead of R, R is ahead of T, T is ahead of U, U is ahead of S, S is ahead of Q. Order: P, R, T, U, S, Q.
Breaking down the clues: T is ahead of U but behind R → R...T...U. S is behind U → ...U...S. P is ahead of R → P...R. Q is just behind S → ...S, Q. Combining: P, R, T, U, S, Q. Linear ordering problems test the ability to synthesize multiple constraints, a key NTS analytical skill.
Question 12: If the day before yesterday was Thursday, what day will it be the day after tomorrow?
- Sunday
- Monday (Correct answer)
- Tuesday
- Wednesday
Correct answer: Monday
Day before yesterday = Thursday, so yesterday = Friday, today = Saturday, tomorrow = Sunday, day after tomorrow = Monday.
Working forward from the given information: Day before yesterday = Thursday → Yesterday = Friday → Today = Saturday → Tomorrow = Sunday → Day after tomorrow = Monday. Calendar reasoning questions like this test sequential logical thinking and are a standard part of NTS analytical sections.
