⚡ Shortcut Tricks for TCS NQT

✅ Aptitude Tricks:

  • Speed, Time & Distance: Use the formula:

Speed=DistanceTime\text{Speed} = \frac{\text{Distance}}{\text{Time}}

➡️ For trains crossing a platform, add the train’s length + platform’s length.

✅ Percentage Conversion Trick:

  • 20% of 450? → Divide by 10, then multiply by 2 → Answer: 90

✅ Probability Tip:

  • Probability of drawing a red card from a deck?

Probability=Favorable OutcomesTotal Outcomes=2652=12\text{Probability} = \frac{\text{Favorable Outcomes}}{\text{Total Outcomes}} = \frac{26}{52} = \frac{1}{2}

✅ Coding Tip for Arrays:
➡️ To find the second largest element in an array:

function secondLargest(arr) {
    let sortedArr = [...new Set(arr)].sort((a, b) => b - a);
    return sortedArr[1];
}
console.log(secondLargest([10, 20, 30, 40, 20])); // Output: 30

🚀 Bonus Preparation Tips

✅ Focus on TCS’s Pseudocode section — It’s common in the exam.
✅ Practice Email Writing using TCS’s official template.
✅ Solve Previous Year Papers for repeated patterns.
