Question

A student's marks rose from 65 to 72. What is the percentage increase?​

Answer 1

Answer:

Thus, the percentage of increased marks is 10.76%.

Step-by-step explanation:

Given,

   A student's marks rose from 65 to 72.

we need to find the percentage increase?

Sol: We know,

                A student's marks rose from 65 to 72.

              Therefore, the marks increased = 72 - 65

                                                                    = 7

        ∴ The percentage of increased marks

                                      $=\frac{7}{65} *100\\=0.10769*100\\=10.76$

Thus, the percentage of increased marks is 10.76%.
