25%

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 / wareagle

pass both tests.

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.

Answer / wareagle

#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?

Answer / wareagle

Aman posted incorrectly again.

52-17=35 students pass in maths only
Class 52% students has passed in Mathematics. Why subtract
7%?
40-17=23 students pass in phy only
40% students has passed in Physics. Why subtract 1&%?

35+23+17=75 students pass in at least one subject..
Total nonsense.

Ans is 100-58=25% students hasn't passed in both the
subjects
Nope. You are wrong again.

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
