Hey

ATQ, let's take the velocities ( of both balls ) as v_0 \ and \ v_1

Since time taken by both is equal, from the first law of motion, we see Vertical component of both velocities are equal ... 

v_1cos \theta = v_0 \\ \\ Now, we \ also \ know \ 2gs = v^2 - u^2 \\ \\ From \ this, we \ derive :-\ \textgreater \ \\ \\ s_0 = \frac{v_0^2}{2g} \\ \\ s_1 = \frac{v_1^2cos^2 \theta }{2g} \\ \\ Hence, the \ ratio \ is \ \ \ \ \frac{s_1}{s_0} = \frac{\frac{v_1^2cos^2 \theta }{2g}}{ \frac{v_0^2}{2g} } = \frac{v_1^2cos^2 \theta}{v_0^2}

Hope it helps ^_^
