Calculate the percentage increase in India's GDP per capita from 2010 to 2020 and state which country between India and Sri Lanka had a higher percentage increase over the same period.
Answer
33.33%, India had a higher increase
The correct answer is 33.33%, India had a higher increase — Compare 33.33% with 9.09% and note that India’s increase is larger.
Step-by-step solution
- Compute India’s increase: 2000-1500=500.
- Divide by base 1500: 500/1500=0.3333.
- Multiply by 100 to get percentage: 0.3333×100=33.33%.
- Compute Sri Lanka’s increase: 2400-2200=200.
- Divide by base 2200: 200/2200=0.0909.
- Multiply by 100: 0.0909×100=9.09%.
- Compare 33.33% with 9.09% and note that India’s increase is larger.
