UP SI Reasoning 2026 Practice Set 8

Below is the UPSI Reasoning 2026 Practice Set 8, designed as a complete revision class covering important and exam oriented reasoning questions. 

Question 1: Analogy - Instruments and Measurements

This question type establishes a relationship between an instrument and what it measures.

• Given Relationship: Ammeter is to Current. An Ammeter measures electric current.

• Task: Find the corresponding relationship for Seismograph.

• Solution: Following the same logic, a Seismograph is an instrument used to measure the intensity of an earthquake (भूकंप की तीव्रता).

• Answer: Earthquake.

Question 2: Classification (Odd One Out) - Vocabulary

The task is to identify the word that does not belong to a given group based on meaning.

• Options: Shortfall, Shortage, Surplus, Deficit, Loss.

• Analysis:

• Shortfall, Shortage, Deficit, and Loss all indicate a deficiency, scarcity, or lack of something.

• Surplus, in contrast, means an excess or an amount left over when requirements have been met.

• Conclusion: Surplus is the odd one out as it denotes abundance, while others denote insufficiency.

Question 3: Number Series

Identify the next number in the series: 5, 9, 20, 37, 78, ?

• Pattern Derivation: The series follows a pattern of multiplying by 2, then alternately subtracting and adding an incrementing number.

• 5 × 2 – 1 = 9

• 9 × 2 + 2 = 18 + 2 = 20

• 20 × 2 – 3 = 40 – 3 = 37

• 37 × 2 + 4 = 74 + 4 = 78

• The next operation is to subtract 5.

• Calculation: 78 × 2 – 5 = 156 – 5 = 151.

• Answer: 151.

Question 4: Complex Coding-Decoding

This problem involves a complex coding pattern with reversed positions and alternate arithmetic operations.

• Pedagogical Strategy: For alphabet-based reasoning, always write down the place value of each letter first. This simplifies identifying numerical patterns.

• Pattern Analysis: The code is generated by applying a pattern from the end of the original word to the beginning of the coded word. It involves two interleaved sequences:

1. An addition sequence (+2, +3, +4, …) for alternate letters.

2. A subtraction sequence (-6, -5, -4, …) for the other alternate letters.

• Applying to PROVINCIAL:

• P (16): The first operation for the last position of the code is +2. 16 + 2 = 18 (R).

• A (1): The next operation is -6. 1 - 6 wraps around to 21 (U).

• R (18): The next operation is +3. 18 + 3 = 21 (U).

• By deriving a few initial letters, options can often be eliminated efficiently.

Question 5: Directions and Distance

Determine a girl's final position relative to her home after a sequence of movements.

• Sequence of Movements:

1. Starts at home, travels 4 km North.

2. Turns right, travels 5 km East.

3. Turns right, travels 4 km South. (This movement brings her back to the original East-West line of her home).

4. Turns right, travels 3 km West.

• Final Position:

• Her North-South displacement cancels out (4 km North, then 4 km South).

• Her East-West displacement is 5 km East - 3 km West = 2 km East.

• Conclusion: To return home, she must travel 2 km West.

Question 6: Calendar - Calculating Future Day

If today is Monday, what day of the week will it be after 61 days?

• Core Concept: Odd Days
  To solve calendar problems, find the number of odd days by dividing the total number of days by 7 and finding the remainder.

• Calculation:

• Total days = 61

• 61 ÷ 7 gives a remainder of 5 (since 7 × 8 = 56, and 61 - 56 = 5).

• Finding the Day:

• Adding 5 days to Monday: Monday + 5 days = Tuesday, Wednesday, Thursday, Friday, Saturday.

• Alternatively, adding 5 days is equivalent to subtracting 2 days in a 7-day cycle: Monday - 2 days = Sunday, Saturday.

• Answer: Saturday.

Question 7: Blood Relations - Symbolic Representation

Identify which symbolic expression represents: "O is the daughter-in-law of M."

• Defining the Relationship: "O is the daughter-in-law of M" means M has a son, and O is that son's wife. M → Son --(married to)-- O.

• Analysis of Option C: M + N / O (Assuming + means mother, / means husband)

1. M + N: "M is the mother of N". (M is female, parent of N).

2. N / O: "N is the husband of O". (N is male, married to O, O is female).

• Combining Statements: If M is N's mother, and N is O's husband, then M is O's mother-in-law. This confirms that O is the daughter-in-law of M.

• Conclusion: Option C correctly represents the relationship.

Question 8: String Manipulation and Positional Logic

This problem involves filtering, sorting, and positional analysis of letters.

• Problem Steps (Example with a hypothetical word):

1. Filter: Remove all vowels from a given word (e.g., from CHARACTER to CHRCTR).

2. Sort: Arrange the remaining consonants in alphabetical order (e.g., C, C, H, R, R, T).

3. Locate: Find the letter that is "second to the left of the sixth from the right".

• Positional Calculation:

• When directions are opposite (Left and Right), add the positions from the reference end.

• 6th from the right and 2nd to the left means 6 + 2 = 8th letter from the right end.

• Finding the Letter: Counting the 8th letter from the right in the sorted list (e.g., Z, T, T, R, R, N, H, **C**) would yield C.

Question 9: Venn Diagrams - Biological Classification

Create a Venn diagram for the terms: Plant Kingdom, Angiosperms, and Pinus.

• Conceptual Hierarchy:

• Plant Kingdom is the overarching category for all plants.

• Angiosperms (flowering plants) are a distinct group within the Plant Kingdom.

• Pinus (pine trees) belongs to Gymnosperms, another distinct group within the Plant Kingdom.

• Relationship: Angiosperms and Pinus are separate, non-overlapping categories, both contained entirely within the Plant Kingdom.

• Visual Representation: The correct diagram shows a large circle for the Plant Kingdom, enclosing two smaller, separate circles, one for Angiosperms and one for Pinus.

Question 10: Numerical Logic

The question presents a numerical relationship: 52 : 14 :: 57 : ?

• Logic: The pattern involves operations on the digits of the first number to derive the second.

1. For 52 → 14:

• Sum the digits: 5 + 2 = 7.

• Multiply the sum by 2: 7 × 2 = 14.

2. Applying to 57:

• Sum the digits: 5 + 7 = 12.

• Multiply the sum by 2: 12 × 2 = 24.

• Answer: 24.

Question 11: Classification (Odd One Out) - States of Matter

Identify the odd one out from a list where three items are liquids, and one is a solid.

• Analysis: This question highlights the distinction between terms. For example, if given water, milk, oil, and sugar. Water, milk, and oil are all liquids. Sugar is a solid.

• Clarifying Terminology:

• Drav (द्रव): Refers to the liquid state of matter. (English: Liquid).

• Dravya (द्रव्य): Refers to matter or substance in general, encompassing all states (solid, liquid, gas). (English: Matter). This distinction is crucial for scientific accuracy in reasoning problems.

Question 13: Visual Reasoning - Figure Completion

This question type requires identifying the correct piece to complete a visual pattern.

• Method: The solution involves analyzing the existing pattern and eliminating options that do not fit the established lines, shapes, and orientation. The correct option logically continues the design, respecting its geometry and direction (e.g., ensuring lines connect correctly and patterns face the intended direction).

Question 14: Logical Inequalities

This problem tests the ability to draw conclusions from a series of inequality statements.

• Core Concepts & Analogy:

• Dominant signs: > and < are considered dominant (like "दादाजी" or grandfather).

• Conflict: If two opposing dominant signs (> and <) appear in the path between two elements, no conclusion can be drawn between them as they create a conflict ("विरोधी" or opponents).

• Analysis of Conclusions (General Example):

1. Conclusion 1 (S vs. L): If tracing the path between S and L shows consistent signs (e.g., all > or >=), a definite relationship can be established.

2. Conclusion 2 (I vs. R): If tracing the path between I and R reveals opposing dominant signs (e.g., S > A < R), no definitive conclusion can be drawn.

Question 15: Dice - Finding the Opposite Face

Find the number on the face opposite to '2', given three different positions of a die.

• Method: Single Common Face
  The most efficient way is to find two dice positions that share exactly one common face.

• Applying the Clockwise Rotation Rule:

1. Identify the common number between two dice positions.

2. From the common number, list the numbers in clockwise order for both dice.

3. The numbers that align in these sequences are opposite to each other.

4. The common number is opposite to the number (from 1 to 6) that is not visible in either of the two chosen positions.

• Example Application (from input):

• Using second and third positions, '1' is common.

• Clockwise from '1' in 2nd die: 1 → 2 → 4

• Clockwise from '1' in 3rd die: 1 → 3 → 6

• Therefore, 2 is opposite 3, and 4 is opposite 6. The remaining number, '5', is opposite '1'.

• Conclusion: The number opposite to '2' is 3.

Analysis of a Flawed Dice Problem and Correct Methodology

Sometimes, competitive exam questions can contain errors. Understanding the fundamental rules of dice problems helps in identifying such flaws.

Identifying Contradictions in Dice Problems

1. Rule: A fundamental rule of a standard die is that two opposite faces can never be seen together (i.e., be adjacent).

2. Contradiction Example: If applying the clockwise rotation rule leads to '2' being opposite '3', but the given figures show '2' and '3' on adjacent faces in one of the die positions, then the problem data is contradictory or flawed.

3. Importance: Identifying such contradictions is not a failure to solve the problem, but a successful application of foundational knowledge to highlight an issue with the question itself.

Systematic Method for Finding Opposite Faces (Reinforced)

The correct method, especially when identifying a single common face, is highly reliable:

1. Identify the Common Face: Locate one number shared between two given positions of the die.

2. Rotate Clockwise: From the common face, list the numbers in a clockwise sequence for both die positions.

• For example, if '5' is common:

• Die Position 1: 5 → 3 → 2

• Die Position 2: 5 → 6 → 4

3. Determine Opposite Pairs:

• The numbers appearing in the same relative position in the clockwise sequences are opposite. In the example: 3 is opposite 6, and 2 is opposite 4.

• The common number (5) is opposite the missing number (1, from 1-6).

Mastering this method allows test-takers to confidently solve correctly framed problems and recognize inconsistencies in flawed ones.
