Simple calculations for every option. You have the answer.
A trick to calculate percentages faster To calculate % growth in population – look at the growth from 1992-1993. Its [(21-20)/20] X 100 = (1/20)X100 = 5%. Now you know that every year the growth is by 1 lakh, but the denominator base (population) is growing. For 1993-1994, its 1/21, for 1994-1995, its 1/22. So as the denominator grows in a fraction, and nominator remains constant, the value of the fraction will be lesser each time i.e. less than 5% for all coming years. So you need not calculate percentage growth for all years and waste your precious time

Analysis of the given data:
The table provides information about the population and total income of a city for four years. Let's analyze the data to find the correct statement.
Population:
- In 1991, the population was 10,000.
- In 1992, the population increased to 11,000.
- In 1993, the population increased to 12,100.
- In 1994, the population increased to 13,310.
Income:
- In 1991, the total income was 50,000.
- In 1992, the total income increased to 55,000.
- In 1993, the total income increased to 60,500.
- In 1994, the total income increased to 66,550.
Per Capita Income:
- In 1991, the per capita income was 5, which is calculated by dividing the total income by the population (50,000 / 10,000).
- In 1992, the per capita income was 5, which is calculated by dividing the total income by the population (55,000 / 11,000).
- In 1993, the per capita income was 5, which is calculated by dividing the total income by the population (60,500 / 12,100).
- In 1994, the per capita income was 5, which is calculated by dividing the total income by the population (66,550 / 13,310).
Explanation of the correct statement:
The correct statement is option 'C' - Per capita income was always above 5,000.
From the given data, it can be observed that the per capita income for each year is 5, which is calculated by dividing the total income by the population. Since the per capita income is consistently 5, it can be concluded that the per capita income was always above 5,000 (as 5,000 is greater than 5).
Therefore, option 'C' is the correct statement based on the given data.
