This question is just asking us to figure out the number in the band at Thalia and at Melpomene, and then subtract them.
At Melpomene, the four categories that include the band add up to 11% + 14% + 26% + 4% = 55%, and 55% of 400 = (0.55)*400 = 220 students.
At Thalia, the four categories that include the band add up to 8% + 10% + 15% + 2% = 35%, and 35% of 700 = (0.35)*700 = 245 students.
The difference is 25 students. Answer = (B).
