## FAQs on Ratio & Proportion CAT Previous Year Questions with Answer PDF

 1. What is the basic concept of ratio and proportion?
Ans. Ratio is the quantitative relationship between two or more quantities, whereas proportion is the equality of two ratios. In other words, ratio compares quantities, while proportion compares ratios.
 2. How do you simplify ratios?
Ans. To simplify a ratio, divide both terms of the ratio by their greatest common divisor (GCD). This will result in the simplest form of the ratio.
 3. How can ratios be used in real-life situations?
Ans. Ratios are used in various real-life situations, such as cooking recipes, financial planning, and map scaling. For example, a cooking recipe may require a ratio of 2 cups of flour to 1 cup of sugar.
 4. What is the difference between direct and inverse proportion?
Ans. In direct proportion, two quantities increase or decrease together at the same ratio. For example, as the number of workers increases, the amount of work completed also increases. In inverse proportion, as one quantity increases, the other quantity decreases at the same ratio. For example, the time taken to complete a task is inversely proportional to the number of workers working on it.
 5. How can you solve ratio and proportion problems?
Ans. To solve ratio and proportion problems, first identify the given ratios or proportions. Then, cross-multiply and solve the resulting equation to find the unknown quantity. It is important to ensure that the units of the quantities being compared are consistent throughout the problem.
