A country has 40% of its population below 15 years and 10% above 65 years of age. The working-age population (15-64 years) constitutes the remainder. What is the total dependency ratio of this country?

• A 50 per 100
• B 83 per 100 ✓
• C 120 per 100
• D 150 per 100

Explanation

Dependency ratio = (Population 0-14 + Population 65+) / Population 15-64 × 100. Here, dependents = 40% + 10% = 50%, and working-age = 50%. So dependency ratio = 50/50 × 100 = 100 per 100. Wait, let me recalculate: 40 + 10 = 50% dependents, 50% working age. Ratio = 50/50 × 100 = 100. None of the options match. Let me revise the question.
