Question

If 80% marks secured by a student are 520 find the total marks of examination

Answer 1

Given:

If 80% of marks secured by a student are 520

To find:

The total marks of the examination

Solution:

The marks secured by a student = 520

The percentage of marks secured by the same student = 80%

Let's assume "x" represents the total marks of the examination.

According to the question, we can form an equation as:

$80\%\:of\:total\:marks = 520$

$\implies 80\% \:of\: x = 520$

$\implies \frac{80}{100} \times x = 520$

$\implies \frac{8}{10} \times x = 520$

$\implies x = \frac{10}{8} \times520$

$\implies x = 10 \times 65$

$\implies \bold{x = 650}$

Thus, the total marks of the examination are → 650.
