एक गाँव की आबादी 5000 है और 2% की दर से हर वर्ष बढ़ती है। दो वर्ष बाद कितनी आबादी होगी?
A. 5108
B. 5200
C. 5202 (Correct answer)
D. 5300
Correct Answer
Option C — 5202
Detailed Solution & Explanation
The correct answer is 5202.
Key Points
Population growth compounds: P(1 + R/100)^T = 5000 × (1.02)².
5000 × 1.0404 = 5202.
Exam Tip
Option (B) 5200 is simple interest thinking (2% of 5000 twice = 200). The extra 2 is the interest on the first year's growth — that difference is exactly what the question is testing.
