A population falls by 12% in the first year. By what percentage must it increase in the second year so that at the end of the second year the population is exactly the same as the original?
10.6%
11.6%
13.6%
14.6%
Answer: C
Assume the original population is 100. After a 12% decrease, it becomes 88. Required increase = (100 - 88)/88 × 100 = 13.636...%, approximately 13.6%.
प्रथम वर्ष में, किसी जनसंख्या में 12% की कमी होती है। दूसरे वर्ष में इसमें कितने प्रतिशत की वृद्धि होनी चाहिए, ताकि दूसरे वर्ष के अंत में जनसंख्या मूल जनसंख्या के बिल्कुल बराबर हो जाए?
10.6%
11.6%
13.6%
14.6%
उत्तर: C
मूल जनसंख्या 100 मानें। 12% कमी के बाद जनसंख्या 88 रह जाती है। आवश्यक वृद्धि = (100 - 88)/88 × 100 = 13.636...%, अर्थात लगभग 13.6%।
