- To find x% of y, we multiply y by x/100.
- The formula is: (x/100) * y = (xy/100)
- For example, to find 25% of 80, we use the formula: (25/100) * 80 = 20
- This concept is widely used in various management entrance exams to test the candidates' ability to calculate percentages and solve word problems.
Word Problems Example:
Question 1: Find 30% of 250.
Solution: (30/100) * 250 = (30 * 250)/100 = 75
Question 2: Ram scored 80% in his exam, out of a total of 500 marks. Calculate his score.
Solution: (80/100) * 500 = (80 * 500)/100 = 400
Tips and Tricks:
- Remember that calculating percentages involves multiplying the percentage value by the total value and dividing by 100.
- It is helpful to convert percentages into fractions or decimals for easier calculations.
- When solving word problems related to finding a certain percentage of a value, identify the percentage and the value correctly to apply the formula accurately.
- Practise previous year's management entrance exam questions to gain familiarity with different types of problems and boost your problem-solving speed.
- Clearly understand the language of the problem and visualise the scenario before attempting to solve it.
- Pay attention to units, especially when dealing with financial or quantitative data.
- Develop shortcuts for percentages like 10%, 20%, 25%, etc. to save time during exams.
