Let the bottle contain x ounces
She drank = 0.25x + 3
Leftover = x - (0.25x + 3) = 0.75x - 3 which is 60% of bottle content
So,
0.75x - 3 = 0.6x
0.15x = 3
x = 20
Hence, option E
She drank = 0.25x + 3
Leftover = x - (0.25x + 3) = 0.75x - 3 which is 60% of bottle content
So,
0.75x - 3 = 0.6x
0.15x = 3
x = 20
Hence, option E
