From the given table, it is clear that the number of students that are more than 24 years old and less than 35 years old fall within two intervals  25  29 and 30  34. In 25  29 interval, there are 60 students and in 30  34 interval, there are 36 students. So, total 60 + 36 = 96 student fall in such category.
Also, total students are 27 + 45 + 60 + 36 + 12 = 180
So, percentage can be calulated as : Favourable/Total * 100
= (96/180) * 100 = 53.3 %
So, percentage of students with more than 24 age but younger than 35 years of age is 53.3 %
