Order And Ranking- Concept, Formula, Practice Question And Answer

0 min read

In logical reasoning sections of banking exams, questions often focus on ranking and order. These questions require arranging objects or people in a specific sequence from left to right or top to bottom.

Understanding Key Concepts

Let us study the key concept of order and ranking:

Basic Principles

Order and ranking revolve around arranging objects or information in a specific sequence based on certain criteria. It involves determining positions or hierarchies.

Order refers to the arrangement of items in a sequence, while ranking assigns positions based on specific rules or comparisons.

Significance In Logical Reasoning

Understanding order and ranking is crucial for developing logical thinking skills. It enhances one's ability to analyze information systematically and make sound judgments.

By mastering these concepts, individuals can effectively prioritize tasks, make informed decisions, and solve complex problems methodically.

Common Structures In Exams

Order and ranking questions often appear in various exams to assess analytical skills. They typically involve arranging elements based on given conditions or comparing attributes to determine positions.

Candidates may need to identify the position of a particular item in a sequence, determine relative rankings among different entities, or deduce missing information based on provided clues.

Exploring Different Ranking Types

Let us study the different ranking types in detail:

Horizontal Vs. Vertical

Horizontal rankings involve items listed side by side, like a leaderboard, where each entity holds a distinct position based on specific criteria. In horizontal lists, entities are compared directly, often in competitive scenarios.

In vertical arrangements, items are stacked based on predetermined criteria without direct competition. Vertical rankings, however, stack items on top of each other.

Numeric Vs. Categorical

Numeric ranks assign a numerical value to each item based on its performance or attributes. Categorical ranks categorize items into groups or classes without assigning specific numbers.

For instance, academic grades use numeric ranking systems to quantify performance levels. In contrast, music charts categorize songs into genres or styles rather than assigning numerical values.

Formula And Application Of Order And Ranking

The formula for calculating order and ranking depends on the context in which it's being used. In the context of arranging or ranking items, there's no single formula.

However, if you're referring to the ordinal position of an item in a sequence, you can simply use: Order= Position+1

Where:

• Order: The ordinal position of the item.

• Position: The position of the item in the sequence (0-indexed).

For example, if an item is in the 5th position in a sequence, its order would be 5+1=6, indicating it's the 6th item in ordinal terms.

Breaking Down Formula

One fundamental formula is the ranking reasoning formula, which calculates the position of an element in a sequence based on certain conditions.

Another crucial formula is the ranking reasoning questions formula, which helps determine the number of elements before or after a particular element.

Application

To apply these formulas effectively, consider various scenarios. For example, when solving a question where individuals are ranked based on height, use the formula to determine a person's rank given their height compared to others.

In another scenario, if you need to find out how many people are ahead of a specific individual in a queue, utilize the ranking reasoning questions formula for accurate results.

Tips For Solving Order & Ranking

Let us study some of the tips for solving order and ranking effectively:

Reasoning

Understanding the reasoning behind order and ranking problems is crucial for accurate solutions. It involves analyzing the given information logically.

When tackling these problems, apply short-cut formulas to save time and solve them efficiently. These formulas help in determining the minimum number of elements in a sequence or arrangement.

Arrangement

Pay close attention to the arrangement of elements in a row or line. Start by identifying the positions of elements, such as right ends and left ends, to establish a clear understanding.

Avoid common mistakes like misinterpreting the positions of elements along a line. Incorrectly identifying the right side or sides can lead to errors in the final solution.

Initial Analysis

Begin by carefully reading the problem to understand the directions and requirements. Identify key cub terms like "highest," "lowest," or "middle." Look for links between different elements.

Establish A Strategy

Determine the bottom line of the question - what is being asked? Break down the problem into manageable sections. Decide on an order to approach each part.

Execute Your Plan

Start with the most straightforward task or element in the problem. Work through each interchange, ensuring accuracy before moving on. Maintain a clear state of your progress.

Evaluate & Adjust

Check your work as you go along, verifying each step's correctness. If you encounter difficulties, revisit your initial strategy and make necessary adjustments.

Selected Practice Questions And Answers

Practice is key to mastering the order and ranking concepts. Here are selected sample questions with answers to reinforce your reasoning ability in order and ranking questions:

Question 1: In a race of 6 people, A finished before B but behind C. D finished before E but behind B. Who finished last?

a) A

b) B

c) C

d) E

Answer: d) E

Explanation: From the given conditions, the order is C - A - B - D - E. So, E finished last.

Question 2: In a class of 30 students, R is 10th from the top; what is R's rank from the bottom?

a) 20th

b) 21st

c) 22nd

d) 23rd

Answer: b) 21st

Explanation: In a class of 30 students, if R is 10th from the top, then R would be 30 - 10 + 1 = 21st from the bottom.

Question 3: In a queue of 50 people, M is 20th from the front; what is M's position from the back?

a) 30th 

b) 33rd 

c) 32nd 

d) 31st

Answer: d) 31st

Explanation: M's position from the back of the queue = Total number of people in the queue - M's position from the front of the queue + 1

M's position from the back of the queue = 50 - 20 + 1= 30 + 1 = 31.

Question 4: In a competition of 5 participants, P scored more than Q but less than R, and S scored less than T but more than P. Who came second?

a) P

b) Q

c) R

d) S

Answer: d) S

Question 5: In a marketing class at an MBA program, six students – A, B, C, D, E, and F – are seated in a row for a group discussion. The seating arrangement is based on their names in alphabetical order from left to right with the following conditions: B is seated somewhere to the right of A. D is seated exactly in the middle of the row. F is seated immediately to the right of E. C is not seated at either end of the row. E is not seated next to A.

Based on the information provided, who is seated at the far right end of the row?

a) B

b) C

c) E

d) F

Answer: a) B

Explanation: C, A, D, E, F, B.

Question 6: In a row of 20 students, Student P is 15th from the front. What is Student P's position from the back?

a) 5th

b) 6th

c) 7th

d) 8th

Answer: b) 6th

Explanation: In a row of 20 students, if Student P is 15th from the front, then Student P would be 20 - 15 + 1 = 6th from the back.

Question 7: In a competition of 7 participants, participant X scored more than Y but less than Z, and participant W scored less than V but more than X. Who came third?

a) W

b) X

c) Y

d) Z

Answer: b) X

Explanation: From the given conditions, the order is Z - X - V - W - U - T - Y. So, X came third.

Question 8: In a friendly coding competition among five friends – Lara, Max, Neil, Olivia, and Peter – the final rankings are announced based on their performance. The following conditions are known: Max finished higher than Lara but lower than Neil. Olivia did not finish last. Peter finished immediately after Lara. Based on the information provided, who finished first in the competition?

a) Lara

b) Max

c) Neil

d) Olivia

Answer: c) Neil

Explanation: Neil is the only person who is explicitly mentioned as finishing higher than others (Max and implicitly higher than Lara and Peter due to the placement of Max and the consecutive finish of Peter after Lara), and since Olivia did not finish last, she can't implicitly finish first based on the condition that Max is lower than Neil.
