Number of drops in a dose = 4 drops
Dose is taken three times a day, therefore,
Number of drops taken in a day = 4*3 = 12 drops
One milliliter = 20 drops
12 mL = 20*12 = 240 drops
Number of days the bottle will last can be find out by calculating total number of drops by the number of drops consumed in a day.
Number of days bottle will last =
Hence,
The bottle will last for 20 days.
