Question

1ml = 32drops from a dropper. If a $15\,ml$ container holds $60$equal doses of medicine, how many drops are in a dose?

Answer 1

Hint: In this question, first we have to find the number of drops in $15\,ml$ of container. We have given the no of drops in \[1ml\]. So, we have to multiply the given drops with $15\,ml$ to find the total number of drops. After that we will divide the given doses with the total number of drops to find the number of drops in one dose.

Complete step-by-step answer:
In the above question, it is given that there are $32\,drops$in one ml.
Also, the total volume given is $15\,ml$.
Therefore, we have to multiply the given drops with the given volume to find the total number of drops.
Therefore, total number of drops $ = 32 \times 15$
$ \Rightarrow 480\,drops$
Now, it is given that $15\,ml$ container holds $60$equal doses of medicine.
Therefore, we can say that $480\,drops$ holds $60$equal doses of medicine.
To find the number of drops in one dose, we have to divide the total drops with the total number of doses.
Therefore, number of drops in one dose $ = \dfrac{{480}}{{60}}$
$ \Rightarrow 8$
Therefore, there are $8$drops in each dose.

Note: In the above question, there is one thing to notice that the volume is equal in each dose. If it was given as unequal, then there will be a problem in finding the answer. Also, the answer will always be a whole number because it is the number of drops.
