First, let's take an example.

Consider there are 10 members in the group and everybody pay 10 paise.
So the total amount collected is the number of members * total money paid by each member = 10*10 = 100.
Now remember this and consider the given question..

Here number of members = Money collected by each member = x
total money collected = x*x
5929 = x^2
X =√ 5929.
x= 77.

Here, it is not given the accurate number of group members, so why we should take a group of 2 members or 3 members?

They will collect "as many paise from each member of the group as is the number of members" that means amount of paise collected from each member is equal the total number of members. As they collected 5929 paise that means there should have been 77 members. And they collected 77 paise from each member.

Why taking the square root of paise?

I didn't understand.

Here first we know when money is collected then this was paise not rupees.

But here the amount given in Rs.59.29 Which is eqal to Rs.59.29=(59.29*100)=5929 paise.

Secondly the conditon is if there was x menmber in a group and one member gives x paise then we can said,
X^2=5929. Or x=77.

Why taking square root in the last step?

The question says "as many paise from each member of the group as is the number of members".that means the numbers of members and the amount donated is the same. There are 77 students and each donates 77 paise so 77*77=5929.

Hence the answer relates to the question.

There is a flaw in this question, the question doesn't mention "each member contributes the same amount", therefore, one could contribute 2 paise, another may contribute 25 paise, another may contribute 50 paise. This will result in an alteration in the no.of the members.

@Vinitha & @Abhinav.

First, you have to understand the problem and convert the paise into a square root.
