# Can You Solve The Intelligence Test That’s Left People On Facebook Confused?

A maths puzzle is boggling minds around the world, but can you solve it?

The test has been shared by thousands on Facebook after it was posted by the page Wikr.com.

To solve the problem, you simply have to work out the number to replace the question mark.

According to Wikr.com, only one in every 1,000 people can master it.

(Read on to discover the answer.)

While one plus four does indeed equal five, two plus five does not equal 12. So, what’s the catch?

The puzzle actually has two possible solutions.

#### Solution One:

1 + 4 = 5.

Then on the next line, add the answer from the previous equation to 2 + 5. That gives you the answer of 12.

The rest of the list will go as follows:

12 + 3 + 6 = 21.

21 + 8 + 11 = 40.

#### Solution Two:

1 + 4 = 5. You could also reach that answer by adding 1 to 4 multiplied by 1.

With the second line, it would be: 2 + (2 x 5) = 12.

The rest of the list will go as follows:

3 + (3 x 6) = 21.

8 + (8 x 11) = 96.

So to solve the puzzle, you can either give the answer 40 or 96. Headache? Us too.
