If a country's population is 1 million and grows by 10 percent in each of two consecutive years, what will the population be at the end of the second year?

Answer and explanation

Correct answer: 1.21 million

Answer: C. Successive percentage growth is applied to the updated population each year. Start with 1 million. After year one, population = 1 × 1.10 = 1.1 million. During year two, the 10% increase is calculated on 1.1 million, not on the original 1 million: 1.1 × 1.10 = 1.21 million. Therefore, the final population is 1.21 million, or 12.1 lakh. A gives only the first year's result. B incorrectly adds 10% + 10% as a simple 20% increase and ignores compounding. D is too high because two 10% increases do not make a 30% increase. Memory cue: for repeated growth, multiply by the growth factor each time; here it is 1.10 × 1.10.
