Read the question carefully!
We will take "AS MANY PAISE AS THE NUMBER OF PEOPLE IN THE GROUP".
it means
if 1 member then he will give as many members in the group i.e 1 paisa
if 2 member then they will give as many members in the group i.e 2 paisa per person. Therefore the tottal amount is 4 paisa
Similarly if there are 77 people in the group then total amount collected is 1529 i.e. 77*77.

@Vishal
From given condition,
No. of paise to be collected = no. of members.
because each member of that group giving one paise.
given amount= Rs.59.29.
coverting rupees to paise, we get 5929ps.
in any case when each one gives same amount as other, we get total
amount in this method i.e amount each one gave*no. of persons.........(A)
in above problem.
if there is one person, we get one paise.
if there are x persons, we get x paise
from the condition ...........(A).
x*x=5929.
then x=77.
Hope you understand.

Lets take a similar example..
Let there are 4 students.
So each member will contribute 4 paise.
i.e., Total amount= 4+4+4+4
=4(1+1+1+1)
=4*4=16.
=4^2
Hence, no.of students= square root of 16(i.e., total sum)which is equal to 4.
Thus we need to do the square root of the total amount.
Similarly relate to the given question.
Let there are 4 students.
So each member will contribute 4 paise.
i.e., Total amount= 4+4+4+4
=4(1+1+1+1)
=4*4=16.
=4^2
Hence, no.of students= square root of 16(i.e., total sum)which is equal to 4.
Thus we need to do the square root of the total amount.
Similarly relate to the given question.

First of all we should divide the given number into two equal pieces it is 5929 so that 59 and 29 are the two pieces.
Now we have to divide the first part with the squares only.
now 10 is remainder.
After that we have to take the second part of the number that is 29.
now the value is 1029.
Previously we took 7 to divide the first now we should take the double of the 7 that is 14.
if the number can divide with 147*7=1029.
remainder is zero.
If it can able to divide 146 then you should multiply with 6. that is 146*6.
Similarly 145*5.
144*4.
143*3.
The last position should be match.
Another example for you.
