General Awareness · solved example
The headquarters of the Northern Railway zone is located at:
Solution
Northern Railway is headquartered at Baroda House in New Delhi. Zonal headquarters are asked almost every cycle, so they are worth learning as a set: Central Railway at Mumbai (CSMT), Southern Railway at Chennai, Eastern Railway at Kolkata and Western Railway at Mumbai (Churchgate).
Mathematics · solved example
A train 180 metres long crosses a pole in 12 seconds. What is its speed in kilometres per hour?
Solution
Crossing a pole means the train covers exactly its own length, so the speed is 180/12 = 15 metres per second. To convert metres per second into kilometres per hour, multiply by 18/5: 15 x 18/5 = 54 km/h. Remember that a train crossing a platform or bridge covers its own length plus that of the platform.
General Intelligence & Reasoning · solved example
Find the missing term: 3, 6, 11, 18, 27, ?
Solution
Look at the gaps between consecutive terms: 3, 5, 7 and 9, which are consecutive odd numbers. The next gap is 11, so the answer is 27 + 11 = 38. Another way to see it: each term is one more than a perfect square, since 3 = 2 squared minus 1, 6 = 3 squared minus 3. The difference method is the reliable first check for any series that grows slowly.

Which Article of the Indian Constitution guarantees the right to constitutional remedies?
Solution
Article 32 gives every citizen the right to move the Supreme Court directly to enforce fundamental rights, which is why Dr Ambedkar called it the heart and soul of the Constitution. For contrast, Article 14 covers equality before the law, Article 19 the six freedoms, and Article 21 the protection of life and personal liberty.

Because a blank carries no penalty, guessing only pays when you can eliminate at least two options. The analysis screen after the test shows you exactly where guessing cost you marks.
