In India, water lillies grow extremely rapidly in the ponds. If the growth enlarged so much that each day it covered a surface double that which it filled the day before, so that at the end of the 20th day if entirely covered the pond, in which it grew, how long would it take water lillies of the same size at the outset and at the same rate of growth to cover the same pond?

we already have lillies that have covered the pond in 20days... now they would cover another pond of double the size in one more day... hence another pond of same size would be covered in half a day.
