There is a body of water that starts with 1 square unit, and doubles in size every day (2 units after 2 days, 4 units after 4 days). It takes 100 days to fill up. How many days would it take to fill if you started with 2 square units?

6 Answers

100 - 1 = 99 days

This question is phrased incorrectly. I think you meant "4 units after 3 days". Which makes your answer wrong as well. This is not helpful at all.

if you start with 1sq unit - lets say you end up with 'x' amount to fill up - takes 100 days if you start with 2 sq unit - you will have to fill up '2x' amount thus it will take - 200 days.
