Question

$33\%$ marks are required to pass an examination. A candidate who gets $210$ marks fails by $21$ marks. What are the total marks for the examination.

• A. $700$
• B. $650$
• C. $600$
• D. $550$

Answer 1

The correct option is A $700$

(a) Let the total marks for the examination be $x$.
Then, $210+21=33\%$ of $x$
$\Rightarrow 231=\frac{33}{100}\times x$

$\Rightarrow x=\frac{231\times 100}{33}=700$.
