**ajay scored 75%in an exam.if his score was 180, find the maximum marks of the exam.**

*x*.

So, 75% of

*x*= $x\times \frac{75}{100}$

Ajay scored 75% of

*x*and his score was 180. So we have;

$x\times \frac{75}{100}=180\phantom{\rule{0ex}{0ex}}\Rightarrow x=\frac{180\times 100}{75}=240$

Therefore the maximum marks of the exam was 240.
