Answer:

A. 39 : 21 : 13

Read Explanation:

Number of students in Economics = 690 × 13/(13 + 7 + 3) = 390 Number of students in Polity = 690 × 7/(13 + 7 + 3) = 210 Number of students in Fashion Education = 690 × 3/(13 + 7 + 3) = 90 Final number of students in Fashion Education = 90 + 40 = 130 final ratio = 390 : 210 : 130 = 39 : 21 : 13
