Answer 1

Answer:

49

Step-by-step explanation:

Let there be x students in the class.

Since, donation by each student is equal to the number of students in the class.

So,

Total donations = 2401

$x \times x = 2401 \\ \\ {x}^{2} = 2401 \\ \\ x = \pm \sqrt{2401} \\ \\ \pm \: 49 \\ \\ \because \: x \: can \: not \: be \: - ve. \\ \\ \therefore \: x = 49$

Thus, the number of students in the class = 49
