The chapter test from maths teacher will contain 15 questions of worth 4 points.

Let the number of questions having weightage of 4 marks be x. Now, we know that problems will only be worth 2 and 4 points. Also we know that some of these problems will be 35. Thus, let us form the equation.

20 + x = 35

Rewriting the equation according to x

x = 35 - 20

Performing subtraction on Right Hand Side of the equation

x = 15

Thus, there will be 15 questions of 4 points.of the maths test to be conducted next week.
