FAQs

What is the answer to the bat and ball riddle? ›

If the ball costs 10 cents, then the bat would cost $1.10, which would bring the total to $1.20. The correct answer is the ball costs 5 cents and the bat $1.05. This question is part of the Cognitive Reflection Test, CRT, which was first described in 2005 by psychologist Shane Frederick.

Mathematically speaking, the correct equation to solve the standard bat-and-ball problem is: $1.00 + 2x = $1.10 (see footnote 1), instead, people are thought to be intuitively using the “$1.00 + x = $1.10” equation to determine their response (Kahneman, 2011).

The answer is actually that the ball costs 5p, because the bat costs £1.05. Two people on the show got the answer wrong and were knocked out. When the question was shared in a clip on TikTok, many were left confused.

The bat-and-ball problem, one of three questions included in the Cognitive Reflection Test, has become a classic index of biased and correct responses in judgment and decision-making research (see Frederick, 2005). It is presented as follows: A bat and ball together cost $1.10. The bat costs $1.00 more than the ball.

As you're reading through the riddle, look for words that have multiple definitions and try solving it for each meaning. Many riddles also use words that have similar meanings to the answer, so try thinking of related words or phrases.

When I take five and add six, I get eleven, but when I take six and add seven, I get one. What am I? ANSWER: A clock.

A quadratic equation with real or complex coefficients has two solutions, called roots.

A solution of an equation is any value of the variable that satisfies the equality, that is, it makes the Left Hand Side (LHS) and the Right Hand Side (RHS) of the equation the same value. To solve an equation is to find the solution(s) for that equation.

Bat-and-ball games (or safe haven games) are field games played by two opposing teams. Action starts when the defending team throws a ball at a dedicated player of the attacking team, who tries to hit it with a bat and run between various safe areas in the field to score runs (points).

Bat-and-ball games are field games played by two teams. They are also known as safe haven (safe zone) games, because players generally score points and take risks by running between various safe zones in the field. These teams take turns "batting" and "fielding." The team that is batting can score.

What was one of the early games played with a bat and ball called? ›

Early baseball was a variant of bat-and-ball games in the medieval world, such as stool ball, old cat, and trap ball. Such games involved hitting, fielding, and sometimes base running, although the rules were few and flexible.

Kahneman explains

The distinctive mark of this easy puzzle is that it evokes an answer that is intuitive, appealing, and wrong. Do the math, and you will see. If the ball costs 10p, then the total cost will be £1.20 (10p for the ball and £1.10 for the bat), not £1.10. The correct answer is 5p.

Students will automatically respond with whoever was mentioned last in the prompt or try to make their own formulas (i.e., the person sitting two seats down from the third person mentioned, etc.) However, the correct answer is the person who speaks first after you ask the question. This is the person who has the ball!

A mathematical riddle is a remark or question phrased purposefully and requires creativity to determine the meaning or answer. Basically, these riddles are more like logical problems which require knowledge of mathematics to solve them.
