Asha got 86.875% marks in the annual examination.

Let $x$ be the total number of marks of the examination.

Then, $86.875 \%$ of $x=695$

$\Rightarrow \frac{86.875}{100} x=695$

$\Rightarrow x=\frac{695 \times 100}{86.875}$

$=800$

$\therefore$ The total number of marks of the examination is 800 .
