(D) First,calculate the total frequency $\Sigma f_{i} = 10 + 12 + 13 + 16 + 9 = 60$.Thus,option $D$ is false because $\Sigma f_{i} = 60$,not $50$.Now,let's verify other options:$1$. Cumulative frequencies: $10, 22, 35, 51, 60$.$2$. Median class: $N/2 = 60/2 = 30$. The cumulative frequency just greater than $30$ is $35$,which corresponds to the class $20-30$. So,option $A$ is true.$3$. Modal class: The highest frequency is $16$,which corresponds to the class $30-40$. So,option $B$ is true.$4$. Cumulative frequency of class $20-30$ is $10 + 12 + 13 = 35$. So,option $C$ is true.
