Answer :
Let x be the number of students in the class. Therefore, total money donated by students:\(x \times x=₹ x^2\)
Here we have, \(x^2 =2401\)
\(\Rightarrow x=\sqrt{2401}\)
\(\qquad \begin{array}{c|lcr}
7 & 2401\\
\hline
7 & 343\\
\hline
7 & 49\\
\hline
7 & 7\\
\hline
& 1\\
\end{array}
\)
\(\Rightarrow x=\sqrt{7 \times 7 \times 7 \times 7}\)
\(\Rightarrow x=7 \times 7 \)
\(\Rightarrow x=49\)
Hence, the number of the students in the class is 49.
