All the rivers are magical, moment a worshiper crosses a river with any number of flowers, it becomes double. (For eg 1 flower becomes 2 flowers, 2 become 4 and so on).

also we can say that after offering flowers at second temple he should be left with x/2 flowers.
similarly after offering flowers at first temple he should be left with (3x/2)/2 flowers.
Thus he should be carrying (x + 3x/4)/2 flowers initially, i.e. 7x/8 flowers initially.
For number of flowers to be integer, x =8, thus he must carry 7 flowers initially and offer 8 flowers at each temple.
