Question

A doctor needs to administer two drugs to a patient. The amount of Drug A administered must be 4 times the amount of Drug B, and the total amount of medication must equal 25 mg. How much of each drug should be given to the patient

Answer 1

Drug A = 20 mg

Drug B = 5 mg

Let's say that Drug B is present in x mg. Drug A must be 4 times as strong as Drug B, hence the dosage must also be 4 times as strong.

A total of 25 milligrams must be used.

Thus, x + 4x = 25

⇒5x = 25

⇒ x = 25/5

⇒5

So, it is recommended to administer 20 mg of Drug A and 5 mg of Drug B.
