Cognitive reflection tests are a fascinating way to gauge our mental agility. Originally devised in 2005 by Professor Shane Frederick, these tests have recently gained traction online. A 2013 survey of 3,500 people revealed that 33% couldn’t answer the questions correctly and 83% got at least one question wrong. This test’s primary goal is to see how well you can recognize that seemingly simple tasks can be trickier than they first appear. Ready to challenge your brain? Let’s dive into this three-question IQ test!

Question 1

A racket and a ball cost a total of $1,100. The racket costs $1,000 more than the ball. How much does the ball cost?

Question 2

If 5 machines can make 5 gadgets in 5 minutes, how long would it take 100 machines to make 100 gadgets?

Question 3

A lily pad in a pond doubles in size every day. If it covers the entire pond in 48 days, how many days would it take to cover half the pond?

Common Wrong Answers

  • Common wrong answer for Question 1: $100

Correct Answers and Explanations

Correct Answer to Question 1: $50

Here’s the breakdown: If the ball costs $50, the racket costs $1,050 (since it’s $1,000 more than the ball). Together, $1,050 + $50 = $1,100.

Correct Answer to Question 2: 5 minutes

If 5 machines take 5 minutes to make 5 gadgets, it means each machine takes 5 minutes to make one gadget. Therefore, 100 machines would still take just 5 minutes to make 100 gadgets, as each machine works simultaneously.

Correct Answer to Question 3: 47 days

Since the lily pad doubles in size each day, it would cover half the pond the day before it covers the entire pond. So, if it covers the entire pond on day 48, it must cover half the pond on day 47.


So, how did you do? This quick IQ test is a fun way to challenge your cognitive skills and see how well you can handle seemingly simple but tricky questions.
