Correct Answer: 7

Solution : Given: The sum of a non-zero number and thrice its reciprocal is $\frac{52}{7}$.
Let the number be $x$.
According to the question,
$x+\frac{3}{x}=\frac{52}{7}$
$\Rightarrow 7x^2-52x+21=0$
$\Rightarrow (7x-3)(x-7)=0$
$\Rightarrow (7x-3)$ or $(x-7)=0$
$\Rightarrow x=7$ or $ \frac{3}{7}$
After checking the options, we get, $x=7$
Hence, the correct answer is 7.
