53-45= 8%

Answer 2

The percentage of increase in her score is 8 percent (%).

Step-by-step explanation:

To find, the percentage of increase in her score = ?

In revision test 1,

225 out of 500 marks

The percent (%) = $\dfrac{225}{500} \times100$

$=\dfrac{225}{5}$

= 45 %

In revision test 2,

265 out of 500 marks

The percent (%) = $\dfrac{265}{500} \times100$

$=\dfrac{265}{5}$

= 53 %

∴ The percentage of increase in her score = 53 % - 45 %

= 8 %

Thus, the percentage of increase in her score is 8 percent (%).
