Aptitude and Reasoning MCQ Questions with Solutions
In a town of 2,00,000 citizens, if the population increases at the rate of 4% per annum, then what will be the population of the town in 2 years from now?
A) 2,10,000B) 3,55,555
C) 1,84,320
D) 2,16,320
Answer & Description:
D) 2,16,320The correct Option is (D) 216320
Initial population = 200000
Population after 1 year :
P(1) = Initial population + Increase in population
= 200000 + 4% of 200000
= 200000 + 0.04 × 200000
= 200000 + 8000
= 208000
Population after 2 years :
Initial population = Population after 1 year = 208000
Now, Population after 2 year = Population after 1 year + Increase in population
P(2) = 208000 + 4% of 208000
= 208000 + 0.04 × 208000
= 208000 + 8320
= 216320
Hence, the population of the town after 2 years from now = 216320
And the correct Option is (e). 216320
