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

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.
