Question

The enrollment of students in a school increases from 560 to 581. Increase in percentage in the enrollment of students is:

• A. 3.75%
• B. $3 \frac{1}{2} \%$
• C. 3.6%
• D. 3.589%

Hint:

For percentage change, always divide the increase by the original value and multiply by 100.

Answer 1

The Correct Option is A

Step 1: Use percentage increase formula
$$\text{Percentage increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100$$ Step 2: Substitute values
$$= \left( \frac{581 - 560}{560} \right) \times 100$$ $$= \left( \frac{21}{560} \right) \times 100$$ $$= 3.75$$ Thus, the correct answer is 3.75%.
