The population of a town increases by 2% per year. If the present population is 49,000, find the population after 2 years.
एक कस्बे की जनसंख्या प्रति वर्ष 2% बढ़ रही है। यदि वर्तमान जनसंख्या 49,000 है, तो 2 वर्ष बाद जनसंख्या ज्ञात कीजिए।
Answer और ExplanationAnswer and explanation
Answer: (B) 50,980
2 साल बाद जनसंख्या (Population) = 49000 × (1 + 2100)2
= 49000 × 1.0404 = 50979.6 ≈ 50980
✓
जनसंख्या लगभग 50,980 होगी।
Population after 2 years = 49000 × (1 + 2100)2
= 49000 × 1.0404 = 50979.6 ≈ 50980
✓
The population will be about 50,980.
SMART APPROACH
2% पर 2 साल = 4.04%। 49,000 का 4.04% = 1979.6, तो 49,000 + 1979.6 ≈ 50,980।
2% for 2 years = 4.04%. 4.04% of 49,000 = 1979.6, so 49,000 + 1979.6 ≈ 50,980.
