There were 100 questions on a math test. If Jamal got 4 times as many right as he got wrong, what was Jamals score?

Jamal's score is 80

Explanation:

Given:

Number of questions = 100

Let w be the number of wrong answers

Let r be the number of right answers

According to question,

r = 4w

r + w = 100

Solving both the equations we get:

4w + w = 100

5w = 100

w = 20

If w = 20 then r = 4 X 20 = 80

Therefore, Jamal's score is 80
