A group of students decided to collect as many paise from each member of group as is the number of members. If the total collection amounts to Rs. 59.29, the number of the member is the group is:
Answer: Option
Explanation:
Money collected = (59.29 x 100) paise = 5929 paise.

Using the value of 100 is an untrue assumed value. Why not use 50 or 75?
Completely disagree. No value was provided and therefore there is insufficient information to correctly solve this problem.
Anyone, please clarify how to solve this.

Square root is taken because the amount of paise each member will give is equal to the number of members in the group so the total amount will be square of the members in the group.

No. of paise to be collected = no. of members = x.
Hence total amount = x * x = (x power 2) = 5929.
Nearest perfect square is 80*80 = 6400
Therefore ans is 77 paise.
Hence total amount = x * x = (x power 2) = 5929.
Nearest perfect square is 80*80 = 6400
Therefore ans is 77 paise.

Dear Suleman, number of paise and number of student both are equal. In this case we always use square root to find them. This concept also based on 9*9 grid (suduko).

59.29 = 5929/100
5929/100*100 = 5929
Here we are calculating in the number of groups so we have do the root
Sqr.Root(5929) = 77
5929/100*100 = 5929
Here we are calculating in the number of groups so we have do the root
Sqr.Root(5929) = 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?

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

How it would be if a remainder is a 2 digit of first division? For eg : sqrt(7921) would be 89 how?
