People have been left baffled by a simple brain teaser involving a T-shirt with several holes in it.

In the photo below, you can see a T-shirt with several holes in it. Your job is to find out how many holes there are in the T-shirt.

Sounds simple? Think again! Most people fail to answer this tricky question correctly in their first try.

If your answer is THREE, we’re sorry to tell you you’re wrong. Don’t lose hope just yet and give it another try!

If you answered SEVEN this time, you are sadly still wrong, and it’s time for us to tell you the correct answer!

As it happens, the shirt in the photo has TEN holes in it. While you can clearly see three holes in the shirt at first glance, keep in mind that you can see through the shirt, meaning that the holes go through the front and the back of the shirt, amounting to a total of 6 openings.

So where did we get the other four holes from? Don’t forget to count the openings at the top and the bottom of the shirt as well as the two holes in the sleeves!

If you’ve had fun with this puzzle, feel free to give a try to the one below as well.

“A bat and a ball cost $1.10 in total,” the second puzzle reads. “The bat costs $1.00 more than the ball. How much does the ball cost?”

If you’re already confident that the right answer is 10 cents, think again.

If the ball costs 10 cents, the bat would have to cost $1.10 due to the fact that the “bat costs $1.00 more than the ball.” In this case, the total price of the ball and the bat would be $1.20 ($0.10 + $1.10).

The correct answer to this puzzle is 5 cents. The ball costs 5 cents, whereas the bat costs $1.05, exactly one dollar more than the ball. Both items in total, therefore, cost $1.10.

If you failed to answer the puzzle correctly, don’t worry. Apparently, many people get it wrong as it is in our nature to attempt to simplify difficult problems by substituting them with simpler ones – in this case, this would mean assuming that the ‘$1.00 more than’ statement refers to the absolute cost of the bat.

Here’s the math behind the puzzle:

Let’s assume that: the bat = x; the ball = y.

We know that: x + y = 1.10

We also know that: x = y + 1.00 (because the bat costs one dollar more than the ball)

Now let’s put these two equations together:

x + y = 1.10

(y + 1.00) + y = 1.10

2y + 1.00 = 1.10

2y = 0.10

y (the ball) = 0.05 (5 cents)
