Question

Study the graph carefully and answer the questions given below it.

$x\%$ of $250+25\%$ of $68=67$, then the value of $x$ is _____.

• A. $10$
• B. $15$
• C. $20$
• D. $25$

Answer 1

The correct option is C $20$

x% of 250+25% of 68=67
$\Rightarrow \frac{x}{100}\times 250+\frac{25}{100}\times 68=67$
$\Rightarrow \frac{x}{2}\times 5+\frac{1}{4}\times 68=67$
$\Rightarrow$ 10x+68=268
$\Rightarrow$10x=200
$\Rightarrow$ x=20
