Basic Mathematics QUESTION #7665
Question 1
Riya scored 72 out of 120 in her first test. After studying, she improved her score by 15%. What is her new score?
  • \(80.2\)
  • \(85\)
  • \(82.8\)✔️
  • None of these
Correct Answer Explanation
Original score = 72. Improvement = \(15\% \text{ of } 72 = \frac{15}{100} \times 72 = 10.8\). New score = \(72 + 10.8 = 82.8\). Therefore, Riya's improved score is 82.8 out of 120.
