Question

Six books are labelled A, B, C, D, E and F and are placed side by side. Books B, C, E and F have green covers while others have yellow covers. Books A, B and D are new while the rest are old volumes. Books A, B and C are law reports while the rest are medical extracts. Which two books are old medical extracts and have green covers?

• A. C and E
• B. B and C
• C. E and F
• D. C and F

Hint:

For logic puzzles with multiple categories and items, creating a simple table is the most effective and error-free method. Make a row for each item (A, B, C...) and a column for each property (Cover, Age, Subject), then fill in the table based on the clues.

Answer 1

The Correct Option is C

This is a logic puzzle that requires creating a table to track the properties of each book. The properties are: Cover Colour, Age, and Subject. 

Let's list the information given: 1. Green Cover: B, C, E, F. This means Yellow Cover: A, D. 2. New: A, B, D. This means Old: C, E, F. 3. Law: A, B, C. This means Medical: D, E, F. 

The question asks for books that satisfy three conditions simultaneously: 1. Must be Old. (The candidates are C, E, F). 2. Must be Medical extracts. (The candidates are D, E, F). 3. Must have Green covers. (The candidates are B, C, E, F). 

We need to find the books that are present in all three of these candidate lists. - List 1 (Old): {C, E, F} - List 2 (Medical): {D, E, F} - List 3 (Green): {B, C, E, F} The common elements in all three lists are E and F.
