Detailed Solution

The bullets are fired at the same initial speed

$\begin{array}{l} \frac{h}{h^{'}} = \frac{u^{2} \sin^{2} 60^{\circ}}{2 g} \times \frac{2 g}{u^{2} \sin^{2} 30^{\circ}} = \frac{\sin^{2} 60^{\circ}}{\sin^{2} 30^{\circ}} \\ = \frac{(\sqrt{3} / 2)^{2}}{(1 / 2)^{2}} = \frac{3}{1} \end{array}$
