let the number of students be X.
So the amount of money each donated also =X
Now,
Total sum of money=X×X
=X²
But,the total sum of money given in question =Rs.2061
So, X²=2061
=> X=√2061
=> X= 45.39[upto 2 decimal places]
=> X= 45.4 [correct to 1 decimal place]
So, total number of students is 45.4
So the amount of money each donated also =X
Now,
Total sum of money=X×X
=X²
But,the total sum of money given in question =Rs.2061
So, X²=2061
=> X=√2061
=> X= 45.39[upto 2 decimal places]
=> X= 45.4 [correct to 1 decimal place]
So, total number of students is 45.4
