Per capita real GDP was $28,900 in France in 2003, and $12,700 in Korea. Assume the growth rates for each country remain the same. 1. Compute the doubling ... remain the same. 2. For Korea, the doubling time will be 72 ÷ 4.2 = 17.1years 3. ... Same with the above, there are 42yrs between 2003 and 2045.

Per capita real GDP was $28,900 in France in 2003, and $12,700 in Korea. We use the rule of 70. The doubling time for France’s per capita real GDP is 70/1.9 = 36.8 years, so France's GDP will double in 2040. Explanation:
