Explanation

To solve the problem, let us assume the total number of boys is $B$ and the total number of girls is $G$. According to the problem:

• $frac{1}{3}$ of the boys are present, so the number of boys present is $frac{B}{3}$
  
• $frac{1}{2}$ of the girls are present, so the number of girls present is $frac{G}{2}$.

The total number of students present is given as:

B​/3+G​/2=Total students present.

Step 1: Check if additional information is provided

• The problem does not give the total number of boys ($B$) or girls ($G$), nor a relationship between $B$ and $G$.
• Without this, we cannot calculate the total number of students present.

Step 2: Conclusion

Since no additional information about $B$ and $G$ is given, the correct answer is:

(D) Data inadequate.
