Question

Day 76,

The water level in a reservoir is low but doubles every day. It takes 60 days to fill the reservoir. How long does it take for the reservoir to become half full?

Answer 1

Answer:

59 days (to become half full from empty). for the case of low level you need to specify the low level in terms of numbers so i can ans accurately.

EXPLANATION:

level doubles everyday. so if today its 10 L then yesterday it must be 10/2= 5L.

So if its full on 60th day, its half full on 59th day.

initially it started with 1/(2^60) units.

Hope this is useful.
