- The concept of finding what percentage one value is of another is a fundamental part of percentage calculations.
- It helps in understanding proportions and relative comparisons between values.
- General formula: \( \text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}} \right) \times 100 \)
- For the concept "x is what % of y," we are given the value of x and y, and we need to find the percentage representation.
Word Problems - x is what % of y
- Word problems often involve real-life scenarios where the application of the "x is what % of y" concept is required.
- Let's solve some previous management entrance exam questions to understand this concept better:
Question 1: A company's revenue was ₹10,00,000, and the profit made was ₹2,00,000. What percentage of revenue is the profit?
Solution: Applying the formula,
Given: Part (Profit) = ₹2,00,000, Whole (Revenue) = ₹10,00,000
Percentage
Therefore, the profit is 20% of the revenue.
Question 2: Ravi obtained 670 marks out of 800 in an exam. What percentage of marks did he score?
Solution: Applying the formula,
Given: Part (Obtained Marks) = 670, Whole (Total Marks) = 800
Percentage
Therefore, Ravi scored 83.75% marks.
Tips and Tricks:
- Remember the formula:
- The "Part" in the formula represents the specific value you want to find the percentage of, and the "Whole" represents the total value.
- While solving word problems, read the question carefully to identify the "Part" and "Whole" values.
- Convert any fractions or decimals to percentages for easy comparison and interpretation of the solution.
- Practice solving multiple problems using this concept to master the calculations quickly.
