UP SI Reasoning 2026 Practice Set 5 – Complete Revision with Important Questions

UPSI Reasoning 2026 Practice Set 5 focuses on enhancing problem-solving skills for competitive examinations by analyzing diverse reasoning problems. It highlights the importance of systematic analysis and careful consideration to avoid common errors, ensuring accuracy and confidence in tackling different question types.

Analogy and Antonyms

Problem: Just as Cyclone is related to Anticyclone, Flood is related to what?

Options: Devastation, Ruin, River, Drought.

Analysis:

The relationship between Cyclone (चक्रवात) and Anticyclone (प्रतिचक्रवात) is one of opposites. The prefix "anti-" signifies this. For Flood (बाढ़), meaning excess water, its direct opposite is a Drought (सूखा), a severe lack of water.

Conclusion: The correct answer is Drought. Identifying the primary logical relationship (antonyms) is vital to avoid selecting associated concepts.

Classification (Odd One Out)

Problem: From the following five, four are alike in a certain way and form a group. Which one does not belong to the group?

Options: Teacher, Student, Engineer, Police, Accountant.

Analysis:

The classification criterion here is whether a term denotes a professional post or a role. Teacher, Engineer, Police, and Accountant all represent specific professional occupations. In contrast, a Student is a role or a phase of learning, typically undertaken before entering such professional roles.

Conclusion: Student is the outlier as it is not a profession.

Number Series (Multiplication Pattern)

Problem: Find the next term in the series: 14, 70, 350, 1750, ?

Analysis:

The series shows a very rapid increase, strongly indicating a multiplication pattern.

• 14 × 5 = 70

• 70 × 5 = 350

• 350 × 5 = 1750

The consistent pattern is multiplication by 5. To find the next term:

• 1750 × 5 = 8750

Identifying Series Patterns Based on Speed of Change: If a series grows very quickly (at "5G speed"), the pattern is likely multiplication or involves exponents. (For slow, steady growth, consider addition; for rapid drops, consider division.)

Conclusion: The next term in the series is 8750.

Directions and Movement

Problem: A woman starts from a point, walks 15 km South, turns left and walks 12 km, then turns right and walks 5 km. Finally, she "turns back" and walks 20 km. How far is she from her starting point?

Step-by-Step Path Analysis:

1. Starts and walks 15 km South.

2. Turns left (from South, left is East) and walks 12 km.

3. Turns right (from East, right is South) and walks 5 km.

4. She then "turns back" (पलटती है), meaning a 180-degree turn. She was facing South, so now she faces North.

5. She walks 20 km North. This movement covers the 5 km she just walked South, and then continues North for another 15 km (20 - 5 = 15). This brings her back to the initial East-West line at a point 15 km North of her turning point.

6. Her final position is 12 km East of her starting point (since the North-South components cancel out relative to the starting East-West line after the "turn back" and 20 km walk).

Comparative Structure: Types of Turns

Conclusion: She is 12 km away from her starting point.

Relative Directions

Problem: A woman walks 9 km East from her home. She turns right and walks 7 km. Finally, she walks 7 km North to reach her destination. In which direction is her home from the destination?

Analysis:

1. Starts at Home, walks 9 km East.

2. Turns right (South) and walks 7 km.

3. From there, she walks 7 km North. This movement effectively negates the previous 7 km Southward travel, bringing her back to the initial East-West axis.

4. Her final position (destination) is exactly 9 km East of her home.

5. The question asks for the direction of the home from the destination.

6. Since the destination is 9 km East of the home, the home must be West of the destination.

Conclusion: Her home is to the West of the destination. It is crucial to identify the correct frame of reference.

Coded Blood Relations

Problem: Find the option that shows "S is the brother of K". The codes are given:

• A + B means 'B's mother is A'.

• A - B means 'B's father is A'.

• A * B means 'B's brother is A'.

• A / B means 'B's sister is A'.

Analysis of Option C: S * Q / K

Let's decode this expression step-by-step:

1. S * Q: According to A * B means 'B's brother is A', this translates to 'Q's brother is S'. This establishes S as male.

2. Q / K: According to A / B means 'B's sister is A', this means 'K's sister is Q'. This establishes Q as female.

Combining the relations:

• S is the brother of Q.

• Q is the sister of K.

• Since S and K share a sibling (Q), they are also siblings.

• As S is male, the combined relationship confirms that S is the brother of K.

Conclusion: Option C correctly depicts the required relationship.

Venn Diagrams (Compositional Relationship)

Problem: Which diagram best represents the relationship between Building (इमारत), Gravel (बजरी), and Pebble (रूढ़ी)?

Analysis:

This problem involves understanding compositional hierarchy: Pebbles are small stones that compose Gravel, and Gravel is a material used in constructing a Building. This nested relationship is best represented by three concentric circles: Pebbles (innermost), Gravel (middle), and Building (outermost).

Conclusion: The correct Venn diagram shows one category entirely contained within the next.

Number Logic

Problem: If 74 is related to 29, how is 63 related?

Analysis:

The pattern involves an operation on the digits of the first number.

• For 74: Multiply the digits and add 1.
  (7 × 4) + 1 = 28 + 1 = 29.

Applying this same logic to 63:

• For 63: Multiply the digits and add 1.
  (6 × 3) + 1 = 18 + 1 = 19.

Conclusion: 63 is related to 19.

Classification (Subtle Social Roles)

Problem: Find the odd one out: Friend, Colleague, Subordinate, Manager.

Analysis:

This question differentiates between peer/support relationships and hierarchical authority. Friend, Colleague (fellow worker), and Subordinate (supporting role) describe peer or assistance-level relationships. Manager is distinct due to its authority and higher position in the hierarchy, overseeing and directing others.

Conclusion: Manager is the outlier as it signifies a position of authority.

Sequence Analysis (Pattern Search)

Problem: In the given sequence of digits, how many 3s are there that are immediately preceded by a 4?

Analysis:

The task is to identify and count instances of the specific two-digit pattern "43" within the provided digit sequence. By carefully scanning the sequence for each occurrence of "43", the total count is found.

Conclusion: There are 4 instances where a 3 is immediately preceded by a 4.

Number Series (Finding the Incorrect Term)

Problem: Find the wrong term in the series: 3, 5, 9, 11, 14, 17, 21.

Analysis:

To identify the incorrect term, we can analyze the pattern of differences or look for an alternating series.

Method 1: Analyzing Gaps

• 3 to 5: +2

• 5 to 9: +4

• 9 to 11: +2

• 11 to 14: +3 (This breaks a potential alternating +2, +4 pattern)

• 14 to 17: +3

• 17 to 21: +4

The inconsistency at +3 suggests a deviation. If the pattern were +2, +4 alternating, after 9+2=11, the next term should be 11+4=15. This indicates 14 is the incorrect term.

Method 2: Double Series (Alternating Series)

Separate the series into two alternating sequences:

• Series 1 (odd positions): 3, 9, 14, 21

• Pattern: 3 + 6 = 9. For consistency, the next term should be 9 + 6 = 15. Then, 15 + 6 = 21.

• This confirms that 14 is incorrect and should be 15.

• Series 2 (even positions): 5, 11, 17

• Pattern: 5 + 6 = 11. 11 + 6 = 17.

• This series is perfectly consistent.

Conclusion: The incorrect term in the series is 14.
