Problema Solution

The population of a certain country was 1.8 million in 2002 and was 2.0 million in 2008. In what year will the population reach 3 million?

Answer provided by our tutors

pop in 2002  = 1.8 million

pop in 2008  = 2 million

 

hence a rise of  .2 million in 6 years

 

for the population to reach  3 million  , it requires .2*5  or  6*5=30 years

 

hence  2038 is the required year....
