at the end of the day , february 14 th , a florist had 120 roses left in his shop , all of which were red , white or pink in color and either long or short - stemmed . a third of the roses were short - stemmed , 30 of which were white and 5 of which were pink . the percentage of pink roses that were short - stemmed equaled the percentage of red roses that were short - stemmed . if none of the long - stemmed roses were white , what percentage of the long - stemmed roses were red ?
"r + w + p = 120 s + l = 120 1 / 3 * 120 = 40 short - stemmed white = 30 short - stemmed pink = 5 = > short - stemmed red = 5 5 / p = 5 / r = > r = p so total long stemmed = 80 and long stemmed red + long stemmed pink = 80 so long stemmed red / long stemmed = ? total white = 30 ( as no long stemmed white ) = > r + r + 30 = 120 = > 2 r = 90 and r = 45 long stemmed r = 45 - 5 = 40 so long stemmed red / r = 40 / 80 = 50 % answer - e"
multiply(divide(divide(multiply(subtract(120, divide(120, const_3)), subtract(subtract(divide(120, const_3), 30), 5)), add(5, subtract(subtract(divide(120, const_3), 30), 5))), subtract(120, divide(120, const_3))), const_100)
