Question

A bottle of tonic contains 240 ml of the medicine. David has been told by the doctor that he should take two teaspoons, thrice a day. Each teaspoon measures 5 ml. For how many days will he be able to take the tonic?

Answer 1

Step-1: Given data

Capacity of a bottle $=240ml$

Capacity of one spoon $=5ml$

Step-2: Calculation of number of days the bottle lasts

David has been told by the doctor should take two teaspoons, thrice a day$=3\times 2=6spoons$

Requirement per day$=6\times 5=30ml$

Number of days bottle lasts $=\frac{240}{30}=8days$

Therefore, the tonic will last for 8 days.
