IQ test: the right answer

Below, we reveal the correct answer to this mathematical puzzle and how to achieve it with the right mathematical reasoning.

The solution

The value of the pizza with one less slice is 10. Here’s how to solve this IQ test.

The first equation gives you the value of a juice: 18 = the sum of 3 juices, so 6 + 6 + 6 = 18, so the value of a juice = 6

The second equation leads to the value of the burger: 12 = 2 burger + one juice = 2 (value of the burger) + 6. You then get burger = 3 such that: 6 + 3 + 3 = 12.

The third equation gives you the value of the fries: 11 = burger + 4 fries = 3 + 2 (value of the fries), so 2 fries = 4 and a box of fries = 2.

Finally, with the last equation, you get the value of a whole pizza as follows:

6 + 3 x 2 = 12.

But since we’re looking for the value of a pizza with one less slice, you then subtract the value of one slice of pizza which is 12 / 6 = 2, because there are 6 slices in all. So the answer is 10.
