FAQs on Tricks for solving Ratio and Proportion Questions Video Lecture - Quantitative Aptitude for CA Foundation

1. What is a ratio and how is it different from a proportion?
A ratio is a comparison of two quantities, while a proportion is an equation that states that two ratios are equal. In other words, a ratio is a simplified form of a proportion.
2. How can I solve ratio problems involving three or more quantities?
To solve ratio problems with three or more quantities, it's important to set up equivalent ratios. Start by identifying the given quantities and their corresponding ratios. Then, set up a proportion with the unknown quantities and solve for the missing value.
3. Can you provide an example of solving a ratio problem step by step?
Certainly! Let's say we have a ratio problem where the ratio of boys to girls in a class is 2:3, and there are 30 students in total. To find the number of boys and girls, we set up a proportion: 2/3 = x/30 Cross-multiplying, we get: 2 * 30 = 3 * x 60 = 3x Dividing both sides by 3, we find: x = 20 Therefore, there are 20 boys and 30 - 20 = 10 girls in the class.
4. Are there any shortcuts or tricks to solve ratio and proportion questions more quickly?
Yes, there are a few tricks that can help you solve ratio and proportion questions more efficiently. One technique is to simplify the given ratios by dividing both sides by their greatest common divisor. Another trick is to convert ratios to fractions, as it can make calculations easier. Additionally, practicing mental math and using estimation can help you quickly approximate the correct answer.
5. How can I check if my answer to a ratio and proportion question is correct?
To check if your answer to a ratio and proportion question is correct, you can substitute your solution back into the original problem and see if the ratios are still equal. Alternatively, you can solve the problem using a different method or approach to verify if you obtain the same result. Checking your work is important to ensure accuracy in ratio and proportion problem-solving.
