Two years ago, population of a city was 16,52,600 which increased by 10% in the first year and by 15% in the second year. Find the present population of the city.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 20,90,539
Each year’s increase is on the population at the start of that year, so the two growth factors are applied one after the other.
After the first year (10% increase): \(1652600\times1.10=1817860\)
After the second year (15% increase): \(1817860\times1.15=2090539\)
The present population is 20,90,539.
