(B) Let $H$ be the set of students who passed in Hindi and $S$ be the set of students who passed in Sanskrit.Given: $n(H) = 60 \%$,$n(S) = 45 \%$,and $n(H \cap S) = 25 \%$.The percentage of students who passed in at least one subject is given by the formula: $n(H \cup S) = n(H) + n(S) - n(H \cap S)$.$n(H \cup S) = 60 \% + 45 \% - 25 \% = 80 \%$.The percentage of students who failed in both subjects is the complement of those who passed in at least one subject.Percentage failing in both $= 100 \% - n(H \cup S) = 100 \% - 80 \% = 20 \%$.

In a class,$60 \%$ of the students pass in Hindi and $45 \%$ pass in Sanskrit. If $25 \%$ of them pass in both subjects,what percentage of the students fail in both subjects?
