Answer:
87%
Step-by-step explanation:
ratio of boys & girls = 5 : 3
number of boys = 5x
number of girls = 3x
total number = 5x + 3x = 8x
failed boys : 16% of 5x = 80x/100
failed girls : 8% of 3x = 24x/100
number of failed : (80+24)x/100 = 104x/100
number of passed : total - failed
= 8x - 104x/100 = 696x/100
passed% = number of passed × 100/total
passed% = 696x × 100/(100×8x)= 87%
