Question : Suppose the Gross Domestic Product (GDP) of Nation X was INR 2,000 crores in 2018-19, whereas the Gross Domestic Product of Nation Y in the same year was INR 120,000 crores.
If the Gross Domestic Product of Nation X rises to INR 4,000 crores in 2019-20 and the Gross Domestic Product of Nation Y rises to INR 200,000 crores in 2019-20.
Compare the rate of change of GDP of Nations X and Y, taking 2018-19 as base year.
Option 1: X= 100%, Y = 66.67%
Option 2: X = 66.67%, Y = 100%
Option 3: X = 101%, Y = 66.67%
Option 4: X = 100.55%, Y = 99%
Correct Answer: X= 100%, Y = 66.67%
Solution : The correct answer is (a) X= 100%, Y = 66.67%
To compare the rate of change of GDP between Nations X and Y, we can use the following formula:
Rate of Change = (New GDP - Base Year GDP) / Base Year GDP * 100
For Nation X:
Rate of Change for X = (4000 - 2000) / 2000 * 100 = 100%
For Nation Y:
Rate of Change for Y = (200000 - 120000) / 120000 * 100 = 66.67%
Therefore, the rate of change of GDP for Nation X is 100%, and for Nation Y, it is 66.67%.
