• A. Class A
• B. Class B
• C. Both A and B are greater than $60\%$
• D. Both A and B are less than $60\%$

Answer 1

Answer: (C)

Given:

In class $A$, $20$ passed out of $25$ with $60\%$ or more marks.

$\Rightarrow$ Fraction of students in $A=\frac{20}{25}=\frac{4}{5}$

In class $B$, $24$ passed out of $30$ with $60\%$ or more marks.

Fraction of students in $B=\frac{24}{30}=\frac{4}{5}$

$\therefore$ Both $A$ and $B$ has equal in fraction of students getting $60\%$ or more marks.

Hence, Option $C$ is correct.
