Question

Kelly requires $36\%$ to pass. She gets $196$ marks and falls short by $20$ marks. Find the maximum numbers she could have got.

• A. $600$
• B. $550$
• C. $650$
• D. $625$

Answer 1

The correct option is A $600$

Kelly had scored $20$ marks more, she could have scored $36\%$.

Now, $20$ marks more than $196$ marks.

$\therefore ,196+20=216$

Let maximum marks be $x$, then $36\%$ of marks $m=216$

$\Rightarrow \frac{36}{100}\times m=216$

$\Rightarrow m=216\times \frac{100}{36}$

$\Rightarrow m=600$

Thus, the maximum marks she could have got were $600$.
