In an article dated april 1, 2011 on the website about.com you could read that india, the world's second largest country, had a population of 1.21 billion. india was expected to pass china by 2030, when it would have more than 1.53 billion people. china's population then would be just 1.46 billion.

a) is the article correct in stating that an annual growth rate of 1.6% means india's population will double in 44 years?

b) assuming that india's growth rate remains 1.6% annually, what will its population be in 2030 when it surpasses china's?
