Temple,Flowers and Magic Pond

There is a lake, of square shape. There are four temples on each
corner. There is a flower tree next to, say temple no 1. The pond has
this magic power, if a flower is dip into the water it doubles the
quantity. There is a warning note from the priest, saying "No flower
should be wasted".

So the puzzle is, how many flowers should be plucked from the tree and
should be offered in the temple and after offering at each temple, no
flower should be left. Each temple has to be offered the same number
of flower. Before offering, flowers has to be dipped in to the pond to
get it double, as he can pluck the flowers from the tree only once, so
he has to be care-full in choosing, the total number of flowers

There are infinite solutions to this problem. Say x flowers are plucked and
y flowers are offered in each temple. then -

2(2(2(2x-y) -y) -y) -y =0
i.e.
16x-15y=0;

any pair the x and y satisfying this equation is a solution.Smallest numbers
are 15, 16
