If 50 people died of heart disease and 200 total deaths occurred in a population during the same period, the PMR for heart disease is:

• A. 100
• B. 25
• C. 50
• D. 200

Answer: (B)

PMR measures the share of all deaths in a population that are due to a specific cause during a given period. It is calculated by dividing deaths from that cause by total deaths, then multiplying by 100 to express as a percentage.

Here, heart disease accounts for 50 of 200 total deaths. PMR = (50 / 200) × 100 = 25%. So the correct value is 25 percent.

The other numbers would imply different proportions: 100 would mean half of all deaths are from heart disease, 50 would mean 50% of deaths, and 200 would mean all deaths were from heart disease.
