FAQs on Multiplying Factor: Percentages Video Lecture - Quantitative Aptitude (Quant) - CAT

1. What is a multiplying factor in percentages?
Ans. A multiplying factor is a value used to multiply another value by a certain percentage. In the case of percentages, the multiplying factor is equal to the percentage value divided by 100. For example, if you want to increase a value by 20%, the multiplying factor would be 1.20 (20/100).
2. How do I calculate the final value after applying a multiplying factor?
Ans. To calculate the final value after applying a multiplying factor, you need to multiply the original value by the multiplying factor. For example, if you have an original value of $100 and a multiplying factor of 1.20, the final value would be $120 (100 x 1.20).
3. How do I calculate the percentage change using a multiplying factor?
Ans. To calculate the percentage change using a multiplying factor, you need to subtract the original value from the final value, divide the result by the original value, and then multiply by 100. For example, if you have an original value of $100 and a final value of $120, the percentage change would be ((120-100)/100) x 100 = 20%.
4. Can a multiplying factor be less than 1 in percentages?
Ans. Yes, a multiplying factor can be less than 1 in percentages. In fact, if you want to decrease a value by a certain percentage, you need to use a multiplying factor that is less than 1. For example, if you want to decrease a value by 25%, the multiplying factor would be 0.75 (100-25/100).
5. How do I convert a percentage into a multiplying factor?
Ans. To convert a percentage into a multiplying factor, you need to divide the percentage value by 100 and then add 1. For example, if you have a percentage value of 25%, the multiplying factor would be 1.25 (25/100 + 1). Conversely, to convert a multiplying factor into a percentage, you need to subtract 1 from the multiplying factor, multiply by 100, and then round to the nearest decimal.
