Question

Find the value of $x$ which satisfies $\sqrt{\frac{x}{7}}=2.74$.

• A. $52.55$
• B. $57.54$
• C. $94.87$
• D. $105.11$
• E. $367.87$

Answer 1

The correct option is A $52.55$

Given, $\sqrt{\frac{x}{7}}=2.74$

$\Rightarrow \frac{x}{7}={2.74}^2=7.5076$
$\Rightarrow x=7\times 7.5076=52.55$
