Q.10 In a class A of 25 students, 20 passed with 60% or more marks; in another class B of 30 students, 24 passed with 60% or more marks. In which class was a greater fraction of students getting with 60% or more marks?


Answer :

In class A, 20 students passed in first class out of 25 students.
\(\therefore \) Fraction of students getting first class
\(\frac{20}{25} = \frac{20÷5}{25÷5} = \frac{4}{5} \)
In class B, 24 students passed in first class out of 30 students.
\(\therefore \)Fraction of students getting first class
\(\frac{24}{30} = \frac{24÷6}{30÷6} = \frac{4}{5} \)
Comparing the two fractions, we get\(\frac{4}{5} = \frac{4}{5} \)
Hence, both the class A and B have the same fractions.
