Option 1 : 35%
In 2018, number of students in Science, Music and Commerce = 600
In 2018, number of students in Commerce = 240
Ratio of number of student in Science and Music = 5 ∶ 7
Required % =( student in Music / total number of students) × 100
In 2018, number of students in Science and Music = 600 – 240 = 360
Ratio of Science and Music students = 5 ∶ 7
So, the number of Music students = 360 × 7 / 12 = 210
Required percent = 210 × 100 / 600 = 35%
∴ Number of students In Music is 35% of total students in year 2018.
