Answer / ravi wadje
a U b = a + b - (a intersect b)
a U b = 52 + 40 - 17 = 75
failes student = 100 - 75 = 25%
So 25% students hasnt passed in exam..!!

Answer / 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

Answer / boopathi
assume 100 stud
1.52 student pass in maths.
2.40 students pass in phy.
3.17 students pass in maths and phy
So.52-17=35 students pass in maths only
40-17=23 students pass in phy only
35+23+17=75 students pass in atleast one subject..
Ans is 100-75=25% students hasn't passed in both the subjects
so,25% of student hasn't pass in both sub.

#16 Incorrect answer. BOOPATHI Did you even look at answer
#15? How did you come up with all that rubbish to post?
The question says "17% students has passed in
both the subjects. So, how many percentage of students
hasn't passed in both the subjects?"
If 17% passed both subjects, then what % did not pass both
subjects. Would it not be 100% - 17% = 83% ? Why do you
want to make it so difficult?
What grade are you in? Did you graduate? Are you looking
for a job?

for example assume 100 students.
1.52 student pass in maths.
2.40 students pass in phy.
3.17 students pass in maths and phy
If you have 100 students 52% = 52 not 1.52 as you posted
40% = 40 not 2.40 as you posted
So.52-17=35 students pass in maths only
17% has nothing to do with math. The question said 52%
passed or 52 students and not 35 as you posted
40-17=23 students pass in phy only
The question said 40% passed physics or 40 students and not
23 as you posted.
35+23+17=75 students pass in at least one subject..
Question said 52 passed Math and 40 passed physics.
How can you say 75 passed at leased one subject?
Ans is 100-58=25% students hasn't passed in both the
subjects
You must be one of the group that failed math.
