Decision Making

Here is a detailed explanation of the Decision-Making.pdf content, along with illustrative examples and additional practice questions for each type of decision-making reasoning problem123. Detailed Explanation of Decision-Making Reasoning Definition Decision-making reasoning involves evaluating given information and conditions to select the best possible outcome or action. These questions test your analytical ability, logical thinking, and judgment based on specified criteria12. Key Concepts Primary Conditions: Essential criteria that must be fulfilled for selection. Additional Conditions: Supplementary criteria that may be considered if primary conditions are not fully met. Data Analysis: Carefully read and analyze each condition and the information provided about each candidate or scenario. Table Construction: Organize information using a table to track which conditions each candidate meets or violates. Decision Rules: Use the table to decide the appropriate course of action for each candidate or scenario. Step-by-Step Approach List Conditions: Write down all primary and additional conditions as column headers. Construct Table: Place candidate names or scenario numbers in rows and mark each condition as: ✓: Condition is satisfied. x: Condition is violated. (✓): Additional condition is satisfied if primary is violated. (x): Additional condition is violated if primary is violated. ? or -: Data is inadequate or not provided. Analyze: Compare each candidate’s information against the conditions and mark accordingly. Decide: Use the table to select the appropriate decision for each candidate or scenario. Illustrative Example Scenario: A computer education center is recruiting faculty. The candidate must:

Direction and Distance

Direction and Distance: Easy Study Material with Emojis, Explanations, and Practice Questions What is Direction and Distance Reasoning? 🧭 This topic tests your ability to follow and visualize directions and distances, often through puzzles where you must determine the final direction faced or the shortest distance between two points. Main Directions & Sub-Directions 🗺️ Main Directions: North (N) ⬆️ South (S) ⬇️ East (E) ➡️ West (W) ⬅️ Sub-Directions: North-East (NE) ↗️ (between North & East) South-East (SE) ↘️ South-West (SW) ↙️ North-West (NW) ↖️ Types of Direction and Distance Questions 🔄 Direction from Initial or End Point Find which way someone is facing after a series of turns. Distance Calculation Find total or shortest (straight-line) distance between two points. Degree-based Questions Turns by certain degrees (clockwise/anticlockwise). Shadow-based Questions Use position of the sun (morning/evening) to infer direction. Key Rules and Tricks 🧠 Turning Right/Left: Facing North: Right ➡️ East, Left ⬅️ West Facing South: Right ➡️ West, Left ⬅️ East Shortest Distance: Use Pythagoras Theorem: $$ \text{Distance} = \sqrt{(\text{East-West})^2 + (\text{North-South})^2} $$ Shadow Rules: Morning: Shadow falls to the West Evening: Shadow falls to the East Sample Questions with Detailed Solutions 📝✨ Q1. Leeta walks 2 km North, turns right, walks 2 km, turns right, walks 2 km. Which direction is she facing? Solution:
