-
Stay Calm and Confident: Solving questions faster reduces stress, helping you focus on exam strategy.
-
Save Precious Time: Tight time constraints make speed calculation techniques essential for effective time management.
-
Simplify Tough Topics: Areas like percentages, ratios, and algebra become easier with the right mental math strategies.
6 Mental Math Tricks to Boost Your CAT Exam Speed
Here are six powerful mental math strategies to help you solve problems faster and more efficiently:
1. Chunking Multiplication for Faster Calculations Break down multiplications into smaller, more manageable parts.
Example: What’s 24 × 18? Split 24 into 20 + 4. Then: (20 × 18) + (4 × 18) = 360 + 72 = 432. Alternatively, use rounding: (25 × 18) - (1 × 18) = 450 - 18 = 432.
This speed calculation technique eliminates unnecessary steps, making it perfect for quant problems.
2. Round and Adjust for Percentages Round numbers to simplify percentage calculations, then tweak the result.
Example: Find 17% of 148. 10% of 148 = 14.8 5% of 148 = 7.4 2% of 148 = 2.96 Total: 14.8 + 7.4 + 2.96 = 25.16 (approximately 25.2).
This is a go-to mental math strategy for data interpretation and approximation-based questions.
3. Memorize Common Fraction-to-Decimal Conversions Knowing fraction-to-decimal values saves time in ratio and proportion problems. _ Example: What’s 1/5 of 85? 0.2 × 85 = 17, solved instantly._
Memorizing conversions like 1/3 ≈ 0.333, 1/8 = 0.125, etc., can significantly improve calculation speed in quant.
4. Quick Squaring Trick for Numbers Near 100 For numbers near 100, use a special squaring formula to solve faster.
Example: What’s 103²? Use the formula: (100 + x)² = 10000 + 2x × 100 + x² (100 + 3)² = 10000 + (2 × 3 × 100) + 3² = 10000 + 600 + 9 = 10609.
This mental math trick is useful for algebra and number system questions.
5. Tackle Easy Questions First Scan the section and prioritize quick, low-effort questions before attempting complex ones. Tip: If a problem looks too time-consuming, skip it for later. Use mental math to quickly assess which problems can be solved instantly.
6. Simplify Division by Breaking It Down Break down division problems into easier calculations.
Example: What’s 378 ÷ 14? Use factors: 378 ÷ 14 = (378 ÷ 7) ÷ 2. 378 ÷ 7 = 54, then 54 ÷ 2 = 27.
This technique eliminates long division, making quant problems faster to solve.
