Two years ago, the population of a city was 2,60,000. If the population decreases by 4% every year, what is its present population?
दो वर्ष पहले, एक शहर की जनसंख्या 260000 थी। यदि जनसंख्या में प्रत्येक वर्ष 4% की कमी हो रही है, तो इसकी वर्तमान जनसंख्या कितनी हैं?
Detailed Solution & Logic
239616
Population decreases by 4% each year, so each year it becomes $0.96$ of the previous year.
After 2 years:
$260000 \times (0.96)^2 = 260000 \times 0.9216 = 239616$
So, the present population is 239616.
