The least common denominator of 3/5 and 1/4 is 20, so assume that there are 20 students at Madison High. (Remember the numbers don’t have to be realistic.) The number of students taking Spanish is 12 (3/5 of 20). Of the remaining 8 students, 2 of them (1/4 of 8) take German. The other 6 take French. Finally, 6 is 30% of 20.
The answer is E
