In a local school district, the high school and middle school each received r dollars toward funding for the student arts program. The high school enrolled 100 students and the middle school enrolled 50 students. Later, the middle school transferred s dollars to the high school so that they would have received the same funding per student. Which of the following is equivalent to s? Choose the correct choice from the following:
A) r/3 B) r/5 C) r/7 D) r/9 E) r/2
Total per head = 2r/150   After s transfer both schools have total for head.   So at High School it will be:   r+s = (100)* (2r/150) = 4r/3   i.e. s = 4r/3 - r/1 =4r-3r/3=r/3   r/3nswer : r/3
