Given : The water level in a reservoir is low, but doubles every day. It takes 60 days to fill the reservoir
To Find : How long does it take for the reservoir to become half full
Solution:
Let say reservoir on 1st day = a
on 2nd day = a* 2 = 2a = 2¹ * a
0n 3rd day = 2a * 2 = 4a = 2² * a
on 60th Day = 2⁶⁰⁻¹ * a = 2⁵⁹ * a
Full = 2⁵⁹ * a
Half = 2⁵⁹ * a /2
= 2⁵⁸ * a
= 2⁵⁹⁻¹ * a
= 59th Day
It will take 59 days for reservoir to become half full
