\[\boxed{\mathbf{1234}\mathbf{.}}\]
\[x - первоначальная\ цена\ \]
\[товара:\]
\[x_{1} = x - x \bullet \frac{24}{100} = x - \frac{6}{25}x =\]
\[= \frac{19}{25}x - после\ снижения\ на\ 25\%.\]
\[x_{2} = \frac{19}{25}x - \frac{19}{25}x \bullet \frac{50}{100} =\]
\[= \frac{38}{50}x - \frac{19}{50}x = \frac{19}{50}x - после\ \]
\[снижения\ на\ 50\%.\]
\[\frac{x_{2}}{x} = \frac{19}{50}x\ :x = \frac{19}{50} = 0,38\]
\[\left( 1 - \frac{x_{2}}{x} \right) \bullet 100\% =\]
\[= (1 - 0,38) \bullet 100\% = 62\% -\]
\[снизилась\ цена.\]
\[Ответ:\ \ на\ 62\%.\ \]
