Hi All,

Certain questions on Test Day can be solved rather quickly with "brute force" - you don't need to be a genius and you don't need to have an 'elegant' approach....you just need to put pen to pad and do a bit of basic math.

Here, we're told that the population DOUBLES every year. We're asked APPROXIMATELY how many years it takes to go from 2,000 to 1,000,000+....

Start: 2,000

Yr. 1: 4,000

Yr. 2: 8,000

Yr. 3: 16,000

Yr. 4: 32,000

Yr. 5: 64,000

Yr. 6: 128,000

Yr. 7: 256,000

Yr. 8: 512,000

Yr. 9: 1,024,000

So, approximately 9 years have to pass to get to 1,000,000+.
