If a student scores 80 out of 100, what is their percentage?

• A. 90%
• B. 75%
• C. 80%
• D. 85%

Answer: (C)

To find the percentage score of a student who scored 80 out of 100, you can use the formula for calculating percentage, which is:

[

\text{Percentage} = \left( \frac{\text{Score}}{\text{Total Score}} \right) \times 100

]

In this case, the student's score is 80 and the total score is 100. Plugging these values into the formula gives:

[

\text{Percentage} = \left( \frac{80}{100} \right) \times 100

]

This simplifies to:

[

\text{Percentage} = 0.8 \times 100 = 80%

]

Therefore, the student's percentage score is 80%. This aligns with the answer provided, confirming that option C is indeed correct. A score of 80 out of 100 straightforwardly translates to 80%, as it represents the portion of the total score achieved by the student.
