Given $ \sum x_n < \infty$ , I need to show that this implies $\sum \frac{\sqrt {x_n}}{n} < \infty $ if $x_n \geq 0$
I thought of using Abel's test to test the convergence but that test couldn't be applied here as $ \sum x_n < \infty \nRightarrow \sum \sqrt{x_n} < \infty$ . I am completely stuck at this point. Any hint how to approach?
