30 students, 24 passed with 60% or more marks. In which class was a greater the
of students getting with 60% or more marks?​

Answer 1

Answer:

both class A and another class are equal % of students getting with 60% or more marks.

Step-by-step explanation:

in class A,

20 passed with 60% or more marks out of25 students.

therefore,

the % of 60% or more marks students is-

in ,

25 students 60% marks students are 20

1 student 60% marks student is 20/25

100 students 60% marks students are (20/25)×100 = 80 that means 80%.

in another class,

24 passed 60% or more marks out of 30 students.

therefore,

the % of 60% or more marks students is-

in,

30 students 60% marks students are 24

1 student 60% marks student is 24/30

100 students 60% marks students are (24/30)×100= 80 that means 80%

both classes of students getting 60% or more marks students % are 80%. that's why both classes equally % of 60% or more marks students.

➥ In class A , 20 students passed out of 25.

So, fraction of class A = 20/25 = 4/5

➥ In class B 24 students passed out of 30

So, fraction of class B = 24/30 = 4/5

➨ Hence, each class have same fraction of students getting 60%
