Title: CAT 2020 Slot 3 LRDI - Indian Game Solutions
In the CAT (Common Admission Test) 2020 Slot 3 Logical Reasoning and Data Interpretation (LRDI) section, there were several questions based on Indian games and related scenarios. Here are some potential solutions to the questions that might have appeared:
Game of Carrom
Question: If a player's score in carrom is 5 more than the score of the player who scores the least, and the highest score is 10 points more than the lowest score, what are the possible scores of the three players?
Solution: Let the lowest score be x. Then, the highest score is x + 10. The score of the player with the middle score is x + 5. Since the scores must add up to a multiple of 5 (as in carrom), the possible combinations are:
x = 0, x + 5 = 5, x + 10 = 15 (Total = 30)
x = 1, x + 5 = 6, x + 10 = 16 (Total = 33)
Continue this pattern to find other valid combinations.
Ludo
Question: In a game of Ludo, four players (A, B, C, D) take turns rolling dice to move their pieces. Player A rolls a 6 and moves his piece from the starting point to the next segment. If the game is played without any player blocking, how many moves will it take for Player A to reach the home segment?
Solution: Each move requires rolling a dice and getting a number equal to or greater than the current segment number. Since Player A has moved from the starting point (1 segment) to the next segment (2 segments), he needs to roll a 2 or higher. The sequence of rolls required could be: 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 6 (since the last roll allows him to reach the home segment). Therefore, it takes 10 moves to reach the home segment.
Snake and Ladder
Question: In a game of Snake and Ladder, if Player E starts at the bottom of the ladder and the last square on the ladder is square 100. The game board has a total of 100 squares. If Player E rolls a dice and moves forward 3 squares, how many rolls will it take on average for Player E to reach the top of the ladder, assuming the game board has equal probability for each square?
Solution: On average, Player E will move forward 3 squares per roll. Since the last square is 100, they need to move 97 squares (100 - 3). If each roll is independent and has an equal probability of landing on any number from 1 to 6, the average number of rolls needed to move 97 squares is 97 divided by the average number of squares moved per roll (which is 3.5, as the average of 1 to 6 is 3.5). Therefore, it will take approximately 97 / 3.5 = 27.714 rolls on average. Since you can't have a fraction of a roll, it would take 28 rolls to reach the top of the ladder.
Please note that the specific questions and solutions can vary, and the above are general examples based on Indian games that might appear in the CAT LRDI section.
Title: CAT 2020 Slot 3 LRDI Analysis & Solutions
Introduction
The CAT (Common Admission Test) 2020 Slot 3 exam included questions across Logical Reasoning, Data Interpretation, and Verbal Ability. This article focuses on solving LRDI (Logical Reasoning, Data Interpretation, and Reading Comprehension)-heavy sections with strategies and sample answers.
1. Logical Reasoning (LR)
Key Topics:
Arrangement/Puzzle (Seating Arrangement, Blood Relation)
Syllogism, Coding-Decoding, Input-Output
Sample Question:
“8 people are sitting in a circle. A is between B and D. C is opposite to E. F is next to G. How many people are between A and F?”
Solution:
Draw a circle and place A between B and D.
Place C opposite E (C-E are diagonally opposite).
Place F next to G (positions depend on remaining gaps).
If A is at position 1, F could be at position 5. The people between them: positions 2, 3, 4 → 3 people.
Strategy: Visualize and use elimination.
2. Data Interpretation (DI)
Format: Table/Graph + 4-5 questions.
Sample Question:
“A survey shows the percentage of students preferring online vs. offline classes in 4 cities (2020). What is the average percentage of students preferring online classes across all cities?”
Solution:
Calculate the average of the given percentages (e.g., 45%, 60%, 30%, 55%).
Average = (45 + 60 + 30 + 55)/4 = 47.5%.
Strategy: Focus on key values, avoid overcomplicating.
3. Reading Comprehension (RC)
Key Tips:
Skim the passage first to identify the main argument.
Answer questions in order (e.g., main idea → inference → vocabulary).
Sample Question:
“The passage discusses renewable energy adoption. Which sentence best supports the claim that solar energy is cost-effective?”
Solution:
Look for keywords: “solar energy,” “cost-effective,” “reduces expenses.”
If the 3rd paragraph states, “Solar panels cut costs by 40% in 5 years,” select that sentence.
4. Verbal Ability (VA)
Focus Areas:
Para Jumble (rearrange sentences for coherence).
Para Summarization (identify the central idea).
Sample Para Jumble:
Sentence 1: The study revealed a pattern.
Sentence 2: Over 70% of participants reported improved sleep.
Sentence 3: The experiment lasted 6 months.
Sentence 4: Researchers analyzed daily habits.
Solution:
Correct order: 4-3-1-2 (Context → Method → Result → Support).
Final Tips for CAT 2020 Slot 3:
Time Management: Allocate 30 mins for DI, 25 mins for LR, 20 mins for VA.
Answer Key: Review mistakes in LR/DI (they hold higher weightage).
Practice: Use past papers to熟悉 question patterns.
Answer Key (Hypothetical):
LR: 3 people | DI: 47.5% | RC: Sentence 3 | VA: 4-3-1-2
