In a Class 52% students has passed in Mathematics, 40%
students has passed in Physics, 17% students has passed in
both the subjects. So, how many percentage of students
hasn't passed in both the subjects?
Answer Posted / wajahat hussain
pass students=17%
(AUB=A+B-Common=75% mean the student pass either Math or Physics.pass mean the student should pass both subjects)
so
failed in Math=100%-52%=48%
failed in Physics=100%-40%=60%
total failed=100%-17%=83%
(Math)U(Phy)= failed(Math)+failed(Phy)-failed in both
83%=48%+60%-common
common=108%-83%=25%
hence 25% failed in both
