Question

The population of a country increased by an average of 2% per year from 2000 to 2003. If the population of this country was 2 000 000 on December 31, 2003, then the population of this country on January 1, 2000, to the nearest thousand would have been

Answer 1

The population as grown 2% per year for 3 years. Therefore the country has grown by 6%.

First I would find out 10% of the population, which is 200,000. Therefore 5% would be 100,000. 1% would be 20,000. Add 5% and 1% which is 120,000.

Finally take away 120,000 from 2,000,000 which is 1,880,000. Therefore the population in 2000 would of been 1,880,000
