Mastering Ratios & Proportion for Aptitude Tests!

Ratio and proportion is another building block for aptitude preparation. Here's a quick guide to sharpen your skills:

1️⃣ What is a Ratio? It's a way to compare quantities. E.g., if you have 2 apples and 3 oranges, the ratio is 2:3. 2️⃣ Scaling Ratios: Multiplying or dividing both terms by the same number keeps the ratio the same. E.g., if salaries in a 3:5 ratio get a 20% hike, the ratio remains 3:5. 3️⃣ Proportions: Two ratios are in proportion if they are equal. If a/b = c/d, then a × d = b × c. This is useful for solving word problems involving relationships between quantities. 4️⃣ Smart Problem-Solving with LCM: When comparing multiple ratios (e.g., a= 3:5 and b= 7:9), use the LCM to align terms for easier comparison. This simplifies complex problems into manageable steps! 5️⃣ Componendo and Dividendo: This is a powerful rule for ratio-based word problems: If a/b = c/d, then (a + b)/(a - b) = (c + d)/(c - d). Mastery of this can save time on tricky questions! 🔑 Quick Tips: - Look for common terms across ratios to simplify your work. - Cross-multiplying helps solve proportions quickly. - Focus on word problems for practical applications of these concepts. The more you practice these concepts, the quicker you'll spot patterns and solve questions faster. Keep it simple, practice smart, and watch your confidence improve!
