Question:
Jacob took a science test and got 24 correct and 16 incorrect answers. What is the percentage of correct answers?
A. 20%
B.40%
C.60%
Answer:
C.60%
Solution:
Given,
Correct Answers = 24
Incorrect Answers = 16
hence,
Total # of questions = Correct Answer + Incorrect Answer
Total # of questions = 24 + 16
Total # of questions = 40
What is the percentage of correct answers?
for this, we can use the concept of Percentage, Base, Rate
P = B × R
where
P = Percentage of Base = 24 (# of correct answers)
B = Base or the Total = 40 (Total # of questions)
R = Rate = ? × 100%
solve for R,
P = B × R
24 = (40) × (R)
R = 24/40
R = 0.6
R = 0.6 x 100%
R = 60%
