Answer to Problem 17P
4 points questions =35 and,
20 points question = 3.
Explanation of Solution
Given information:
Total number of questions = 38.
Total points = 200.
Question consist of 4 points and 20 points.
Calculation:
Let’s us consider that
4 points questions = X and
20 points question = Y
Therefore, according to question,
Solving equation (i) we get-
Putting the value of X in equation (ii) we get-
Therefore,
Now putting the value of Y in equation (i) we get-
So,
4 points questions =35 and,
20 points question = 3.
