Question

Which of the given values should replace the question mark in the following question?

$12$% of $980$ $-?$% of $450=30$% of $227$

• A. $14$
• B. $17$
• C. $11$
• D. $8$

Answer 1

The correct option is C $11$

Given, $12\%$ of $980-x\%$ of $450=30\%$ of $227$
$\Rightarrow \frac{12}{100}\times 980-\frac{x}{100}\times 450=\frac{30}{100}\times 227$
$\Rightarrow \frac{x}{100}\times 450=117.6-68.1=49.5$
$\Rightarrow x=\frac{49.5\times 100}{450}=11$
