Question

If $\frac{4x}{5}+7=12$,then the value of $x$ is-

• A. $\frac{4}{25}$
• B. $-\frac{4}{25}$
• C. $\frac{25}{4}$
• D. $-\frac{25}{4}$

Answer 1

The correct option is C $\frac{25}{4}$

$\frac{4x}{5}+7=12$
$\Rightarrow$ $\frac{4x}{5}=12-7$
$\Rightarrow$ $\frac{4x}{5}=5$
$\Rightarrow$ $x=\frac{5\times 5}{4}$
$=\frac{25}{4}$
