The Correct Option is A
Solution and Explanation
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%.
\[ \text{Percentage increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \] 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%.
