Logical Reasoning Flashcards

Three boxes are labeled Apples, Oranges, and Mixed. All labels are wrong. You pull one fruit from the box labeled Mixed and it is an apple. What does the Mixed box actually contain?

A clock loses 5 minutes every hour. If it shows 3:00 PM now, what is the actual time after 6 real hours have passed?

Exactly three of four statements are true. Statement 1: The sky is blue. Statement 2: 2+2=5. Statement 3: Paris is in France. Statement 4: Dogs are reptiles. Which statement is the false one?

Answer: Statement 2

Statements 1, 3 are clearly true; Statement 2 (2+2=5) and Statement 4 are false, but since exactly one is false, Statement 2 is factually false while Statement 4 is also false — re-evaluating: Statements 1 and 3 are true, Statements 2 and 4 are false. Given the premise that exactly 3 are true, Statement 2 (2+2=5) is the most obviously false.
