Answer:
Step-by-step explanation:
Total no.of students=200
Boys=150
So , girls=50
120 Passed
So, 80 failed.
Out of 80 - 10 r girls and 70 r boys
Percentage of boys passed= 80*100/150=53.34%
Percentage of girls passed= 40*100/50= 80%
GIrls to boys ratio : 50:150 = 1:3
Success ratio between boys and girls : 3:2
Hope this helps!!!!
