How smart you are? ( test)

Some tasks are designed so that everyone can check their level of intelligence.

Take a close look at the following task:

It looks like a very simple mathematical equation. Can you find the right values ​​for A and B to get the indicated numbers as a result?

If A plus B is 76, and in the case A minus B turns out to be 38, what will be the result of A division by B?

Please note that there are many combinations, the addition of which make the number 76. However, the meaning of the task is to choose the values ​​of A and B so that all three equations are solved correctly.

So, if you coped with the task in less than one minute, it means that you have a very high intelligence. In other words, you are a real genius.

If it took you two to five minutes to complete the task, it means that you are a smart and rather quick-witted person.


But if the test task took you more than 10 minutes, this means that you need to train and solve logical tasks as often as possible.

Here is the answer:

A division by B will be equal 3.

A = 57 B = 19

How can you solve this:

• So, the result of the first equation is twice the result of the second equation (76 and 38). 
• Therefore, A + B = 2 (A - B). 
• From this, it follows that A + B = 2A - 2B 
• and further B + 2B = 2A - A, 
• giving 3B = A 
• and, therefore, A division by B = 3

Write in the comments, if you solve the task, and how much time you spent on it.
