Answer:
China' s real GDP per capita would be $16,000 in 20 years
Explanation:
Rule of 70, states that divide 70 with the growth rate and will get the time it will take, for an amount to get twice its present value.
After 10 years,
China's GDP would be the twice of GDP per capita.
In numerical terms
= 2 × GDP per capita
So, after 20 years, it would be 4 × GDP per capita
Therefore,
= 4 × $4,000
= $16,000
