Answer:## Hii mate here is ur answer plz mark me as brainlist….

Step-by-step explanation:Students pass in Maths = 60%

Students pass in English = 50%

Fail in both = 30%

Students pass in at least one =

100% – 30% = 70%

We know n( A or B)=n (A )+n( B)-n(A and B)

70%=60%+50%- n (And B)

So number of students pass in both =110%–70%=40%.

In a class, 60% of the students pass in English and 45% pass in Hindi. If 25% of them pass in both subjects, what percentage of the students fail in both the subjects?

In a class, 80% of students pass in maths exam and 70% of students pass in English exam. 10% of students fail in Both subjects and if 144 students pass in Both subjects. Find the total number of students?

In an examination, 70% of students pass in mathematics, 65% student pass in English, 27% student failed in both subjects. What is the total number of students?

Out of some students appeared in an examination, 80% passed in English, 75% passed in science and 5% failed in both subjects. If 300 of them passed in both subjects, how many students appeared in the examination?

In an exam, 60% passed in maths and 65% passed in English. If 25% failed in both, what is the percentage of students who passed in both?

Let number of students be X

Then 60% of X passed maths which is 0.6X students,

50% of X passed English which is the same way 0.5X students, and then finally 30% of X failed both which is also 0.3X students.

From set

U = X

X= 0.6X+0.5X+0.3X-?

X=1.4X-?

X-1.4X=-?

-0.4X=-?

?=0.4X

By percentage that’s 40%.

if 60% passed Math, then 40% failed Math

if 50% pass English, 50% fail

30% fail in both.

Well if 40% failed Math only because 30% failed both, then we know that 10% must have failed only Math.

And if 50% failed English because the first 30% failed both that means 20% failed English only.

Thus we have 30% who failed both, 10% who failed only Math, and 20% who failed only English leaving us with a grand total of 60% who failed something and 40% failing nothing.

fail in Math=100–60=40%

fail only in Math=40–30=10%

again, fail in English=100–50%

fail only in English=50–30=20%

Now, total fail=10+20+30=60%

So,pass in both subject=100–60=40%

Answer:40%

If 60% of people passed in math and 70% passed in English, what is the minimum percentage of those who failed in both?

In an examination, 70% of the candidates passed in English, 80% passed in mathematics, and 10% failed in both subjects. If 144 candidates passed in both, what is the total number of students?

In an examination, 75% candidates passed in English and 60% passed in Mathematics. 25% failed in both and 240 passed the examination. Find the total number of candidates?

In an examination, 78% of the candidates passed in English, 67% passed in Mathematics and 10% failed in English and Mathematics both. Find the pass percentage of those who passed in both subjects?

In an examination 40% of the students failed in English, 60% passed in Mathematics. If 10% of the students failed in both the subjects, what is the pass percent?

passed in Mathes = 60%

Passed in English=50%

Total = 110

failed in both 30%

Passed=100-30=70

%Passed in Both=110-70 = 40
