Boys in class = (5/8) x 96 = 60, So girls=96 - 60 = 36 Sports persons among boys = (7/12) x 60 = 35, So non-sports persons = 60 - 35 = 25 Total sports person in class=2/(2 +1) x 96 = 64, So non-sports persons = 96 - 64 = 32 So Sports persons among girls = 64 - 35 = 29, non-sports = 32 -25 = 7 Therefore, ratio=29:7
