Explanation of Solution

The growth rate in real GDP can be calculated using the following formula:

Growth rate in real GDP=[(Real GDPNewReal GDPOld)Real GDPOld]×100 (1)

Using the formula (1), the growth rate in real GDP from 2011 to 2012 of United States, El Salvador, Republic of South Africa, Cambodia, and Russia can be calculated as follows:

Growth rate in real GDP in U.S = (15,556.8615,20415,204)×100=2.32%

Real GDP growth rate in U.S. is 2.321%.

Table-1 shows the real GDP growth rate in different countries, which is obtained using Equation (1).

Russia3.44%

Among these five countries, Cambodia experienced the highest rate of economic growth.

Explanation of Solution

The average annual growth rate in real GDP from 2011 to 2014 for U.S. can be calculated as the sum total growth rates divided by 3 as follows:

Annual growth rate of real GDP in U.S = (2.32%+2.22%+2.32%3)=2.29%

Annual growth rate of real GDP I U.S. is 2.29%.

The average annual growth rate in real GDP from 2011 to 2014 for El Salvador can be calculated as the sum of the total growth rates divided by 3 as follows:

Annual growth rate of real GDP in El Salvador = (1.87+1.70+2.203)=1.92%

Annual growth rate of real GDP in EL Salvador is 1.92%.

The average annual growth rate in real GDP from 2011 to 2014 for Republic of South Africa can be calculated as the sum of the total growth rates divided by 3 as follows:

Annual growth rate of real GDP in Republic of South Africa =(2.47%+1.89%+3.503) =2.62%

Annual growth rate of real GDP in Republic of South Africa is 2.62%.

The average annual growth rate in real GDP from 2011 to 2014 for Cambodia can be calculated as the sum of the total growth rates divided by 3 as follows:

Growth rate in real GDP in Cambodia =(7.35%+7.47%+7.31%3) =7.38%

Annual growth rate of real GDP in Cambodia is 7.38%.

The average annual growth rate in real GDP from 2011 to 2014 for Russia can be calculated as the sum total growth rates divided by 3 as follows:

Growth rate in real GDP in Russia =(3.44%+1.32%+0.25%3) =1.67%

Annual growth rate of real GDP in Russia is 1.67%.

Among these five countries, Cambodia experienced the highest average annual rate of economic growth from 2013 to2014.
