In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

    Simple solution.... If every day the size of the patch doubles and it takes 48 days to completely fill the lake; then on the 47th day the lake would be half covered. Why? If the size of the patch is half the size of the lake, then one day later the patch has doubled.

    it is half full on day 47 every day it doubles so on day 48 it is full

    And double of 1/2 is 2*(1/2)=1... i.e. the size of the whole lake

    So as studio also pointed out, it takes 47 days for the patch to reach the half-way point, and the last day it fully covers the lake.
