Question

a country's population in 1992 waa 83 million and in 1996 was 88 million what was the population in 2013

Answer 1

The population in 1992 was 83 mill....population is 1996 was 88 mill...

so in 4 years (from 1992 to 1996), the population rose by (88 mill - 83 mill) = 5 mill

Thats 5,000,000 / 4 = 1,250,000 per year.

so in 2013 (17 years from 1996), the population would be :
83 mill + 1,250,000(17) = 83 mill + 2,125,000 = 85,125,000 <==
