You may have already come across those tests in which the picture shows some items that represent hidden numbers, and by the accuracy of the calculation given, you can decipher the numbers that those items stand for.
Kind of confusing, right? But when you see the test below, you will undoubtedly understand what is being said here. The important thing with this question is knowing what these tests are for, after all, it’s not just about crunching the calculations and thinking you’re a mathematical genius for it.
In fact, this type of device, as you will see shortly after completing this test, is commonly used by teachers to perform mathematical calculations that involve the use of letters and numbers in a more attractive way for their students.
Therefore, this type of test has been very popular for a while on the Internet, not least because of the attention to detail it requires, as well as the obvious need for mathematical knowledge.
Therefore, taking these tests is a great and fun way to develop your mind and improve your ability to solve mathematical problems, which can help you at various times in your life, whether in tests or at work.
Can you tell the result of this problem?
Using the McDonald’s fast food franchise menu, this test is very easy to understand, it is enough that as a result of the calculation, you can find out the value attributed to each of the three items in the picture, being the drink, the hamburger and the fries.
However, as you can see in the image below, solving this question can be more difficult than understanding it, so let’s test it. Take as much time as you want and say what outcome does the “?” represent.
then? You managed to solve the mathematical problem, if you did not, we will explain how it is solved and, in fact, what it is.
To solve the question, you’ll notice that drink + drink + drink = 30. This indicates that the drink, in this case, is worth 10. Knowing that, we see that the bottom line is: drink + hamburger + hamburger = 20, so, as if you already know Since a drink is worth 10, it stands to reason that a hamburger is worth 5 each.
The third line is the one that causes the most confusion, because some people attribute the value of the potato to 2, and that’s because the hamburger is equal to 5, so to get to 9, you need another 4, so the value of each of the potatoes will be 2.
But it turns out that in the picture, we see 4 fries, because the line shows: hamburger + 2 fries + 2 fries = 4, so the fries are equal to 1. From here, it is easy to see the result, because: hamburger (5) + fries (1) x Drink (10) = 15.
But what about this problem being a way for teachers to make math easier? The truth behind this image is that its real syntax is:
a + a + a = 30
a + b + b = 20
b + 2c + 2c = 9
b + c. a = x
When teachers begin to use letters to solve mathematical problems, many students are frightened and feel pressured by the changes in the symbols.
Therefore, the use of common items, such as fast food, for example, can be a solution to relieve the stress experienced by some students, especially the younger ones, from the difficulties of the questions.
