Question 774995
<font face=Tahoma size=2>
<font size=4><b>
Remember, {{{Score = correct_answers/total_questions}}}*{{{100%}}}
.
Given:
{{{score=92}}}
{{{correct_answers=11}}}
{{{total_questions =unknown}}}=<font color=red>X

.
Substituting,
{{{92=(11/x)(100)}}}, cross multiply
{{{92x=1100}}} ---> {{{cross(92)(x)/cross(92)=1100/92}}}
<font color=red>x=12, answer
.
Check,
{{{score=(11/12)(100)}}}
{{{score=92}}}
.

Thank you,
