A number when increased by 50 %', gives 3030. The number is:
1010
6060
2020
4040
2020
To find the number when it is increased by 50 percent to get 3030, we can set up the equation x + 0.50x = 3030, which simplifies to 1.50x = 3030. Solving for x gives 3030 divided by 1.50, resulting in 2020. Alternatively, 3030 represents 150 percent of the original number, so the original number is (3030 * 10тБ░) / 150 = 2020.

Percentage calculations form the fundamental basis of quantitative aptitude in competitive examinations, governed by basic arithmetic proportions and ratio analysis.
An increase of 50 percent means multiplying the original number by 1.50.
Dividing the final value (3030) by 1.50 yields the original base value.
Percentage problems can be solved quickly using fractional equivalents (50% = 1/2, so 1 + 1/2 = 3/2).
Option A (1010) represents 50 percent of 2020, which is the amount added, not the total number.
Option B (6060) would be the result if the number was decreased incorrectly or represents a miscalculation.
Option D (4040) would be the result if 3030 was 75 percent or calculated with a different ratio.
C is correct тАФ The number when increased by 50% to give 3030 is 2020.
