Content: Indian National Test Preparation Guide
The CAT (Common Admission Test) 2020 exam's Slot 1 (Logical Reasoning, Data Interpretation, and Reading Comprehension) section posed challenging questions across its three main segments. Below is a structured breakdown of potential question patterns, solved examples, and key strategies for LRDI (Logical Reasoning, Data Interpretation) in CAT 2020 Slot 1.
1. Logical Reasoning (LR) – Key Trends & Solutions
Common Topics in CAT 2020 Slot 1 LR:
Puzzles (Seating Arrangements, Blood Relations, Floor Plans)
Categorization & Grouping
Alphanumeric Series
Caselet Analysis
Example Question (Hypothetical):
“Six friends (A, B, C, D, E, F) are sitting in a row. B is to the immediate right of E. A is to the left of D but not adjacent. F is at one end. Who is third from the left?”
Solution:
Visualize Positions:
Possible arrangements: _F _ _ _ _ _ / _ _ _ _ _ F
B is to the right of E → E _ B _ _ _ or _ _ E _ B _
A is left of D but not adjacent → A _ _ D or A _ D _
Combine constraints:
If F is on the left: F, E, B, A, D, C → Valid.
Third from left: B.
Strategy:
Step-by-Step Elimination: Use process of elimination for seating puzzles.
Keyword Clues: Focus on "immediate," "not adjacent," and "exactly one end."
2. Data Interpretation (DI) – CAT 2020 Slot 1 Insights
Common DI Formats in Slot 1:
