english or both the subjects. Then what is
the percentage of students passed In both
the subjects?​

Answer 1

Step-by-step explanation:

10 PERCENT STUDENTS PASSED IN ALL SUBJECTS

Answer 2

The percentage of students passed In both the subjects is 10%.

Given:

Percentage of students passed in telugu= 60%

Percentage of students passed in english= 50%

Number of fail students= 0

To find:

The percentage of students passed In both the subjects. {n(TnE)}

Solution:

• Set is a collection of well- defined objects or elements.

Let T be the set of students who have appeared for telugu subject and E be the set of students who have appeared for english subject.

Percentage of students passed in telugu=n(T)= 60%

Percentage of students passed in english=n(E)= 50%

Since, every student passed in either telugu or english or both the subjects.

So, n(T u E)= 100%

To find the percentage of students passed In both the subjects {n(TnE)} we have to use the formula:

n(TnE)= n(T)+n(E)-n(T u E)

n(TnE)= 60+50-100

n(TnE)= 110-100

n(TnE)= 10%

Therefore, the percentage of students passed In both the subjects is 10%.
