Suppose nominal gdp in 2009 was $100 billion and in 2010 it was $260 billion. the general price index in 2009 was 100 and in 2010 it was 180. between 2009 and 2010, the real gdp rose by approximately

The real GDP increased by 44%.

Explanation:

The nominal GDP is the measure of economic growth which measures change in output at the current market price.

While, the real GDP calculates the change in output at constant prices. It is inflation adjusted method and does not include change in price level. It purely measures the change in economic output.

The consumer price index = Nominal GDP/Real GDP

In other words, Real GDP= Nominal GDP/consumer price index

Real GDP in 2009==$1

Real GDP in 2010==$1.44

So, the GDP growth rate will be, $(1.44-1)*100=44%
