Correct Answer: Option A
Explanation:
\(70 \%\) students passed in physics \(=30 \%\) failed in Physics.
\(65 \%\) students passed in Chemistry \(=35 \%\) failed in Chemistry
Percentage of students failed in both subject \(=27 \%\).
Percentage of students failed \(=35+30-27\)
\(=38 \%\).
Percentage of students passed \(=100-38 \%=62 \%\)
\(70 \%\) students passed in physics \(=30 \%\) failed in Physics.
\(65 \%\) students passed in Chemistry \(=35 \%\) failed in Chemistry
Percentage of students failed in both subject \(=27 \%\).
Percentage of students failed \(=35+30-27\)
\(=38 \%\).
Percentage of students passed \(=100-38 \%=62 \%\)
