✔ 最佳答案
the longest time of female = 15 minutes
the number of males took less than 15 minutes = 12
the number of all students = 27
the required percentage = 12/27 x 100% = 44.4%

the least time of female = 2.5 minutes
the number of males took longer than 2.5 minutes = 13
the number of all students = 27
the required percentage = 13/27 x 100% = 48.1%
