Question

A Patient A receives 3 times the amount of certain medicine as Patient B. The two doses add to 200 milligrams. What amount of the medicine does each patient receive?

Answer 1

Answer:

A = 150 milligrams

B = 50 milligrams.

Step-by-step explanation:

Let the medicine received by patient B be x.

According to the question patient A receives 3 times as much.

So patient A receives 3x.

The total amount of medicine administered to the two patients equals to 200 milligrams.

We write this relation as follows :

x + 3x = 200

4x = 200

x = 200/4

x = 50

Patient B receives 50 milligrams.

Patient A receives 3 × 50 = 150.milligrams.
