The answer would be 7. 15.265
The answer is 9
6 divided by 2 (1 + 2)
= 6 divided by 2 x 3
= 3x3
= 9.

Both boys get 14 problems <em>correct </em>of the <em>entire</em> test composed by 120 problems.
<h3>Procedure - Determination of the number of problems that Andy and Bob got correct in a test</h3>
In this question we must determine how many questions Andy and Bob got correct. The total of problems (
) is the sum of problems that neither got correct (
), problems that only Andy got correct (
) and problems that both boys got correct (
). Hence, we have the following algebraic expression:
(1)
And according to the statement, the relationships between the number of problems got correct by Andy and the number of problems that Bob got correct (
) is described by the following expressions:
(2)
(3)
If we know that
and
, then the solution to this system of linear equations is:
(1)
(2)
(3)
The solution of this system is:
,
,
.
Since the quantity of <em>solved</em> problems must be integers, we have the following approximate solution: 
Hence, we conclude that both boys get 14 problems <em>correct </em>of the <em>entire</em> test composed by 120 problems.
