दोन रेल्वेगाड्या एकाच दिशेने अनुक्रमे 112 किलोमीटर/ताशी व 76 किलोमीटर/ताशी या वेगाने धावत आहेत. वेगवान गाडी ही धीम्या गाडीत बसलेल्या एका व्यक्तीला 20 सेकंदात ओलांडते तर वेगवान गाडीची लांबी किती ?
This MPSC previous-year question is drawn from MPSC Group B Combined Pre 2026 (Marathi). It belongs to the Aptitude section and is reproduced here in Marathi exactly as it appeared in the official Maharashtra Public Service Commission paper, along with the four options, the official Set A answer key and a compact explanation of why the correct option is correct.
Correct answer: B
Explanation
बरोबर पर्याय B आहे. एकाच दिशेने जाताना सापेक्ष वेग = 112 − 76 = 36 किमी/तास = 10 मी/सेकंद. प्रश्नात दिलेल्या ओलांडण्याच्या वेळेत 10 मी/सेकंदने रेल्वेची लांबी 200 मीटर येते.
Why this question matters
The Maharashtra Public Service Commission recycles aptitude question patterns across its main five recruitment examinations. Solving a PYQ from one paper substantially increases your accuracy on adjacent papers because the underlying facts and the option-craft are identical. That cross-transfer is the strongest argument for prioritising PYQ practice over generic textbook review.
How to attempt this in the exam
Read every option twice before committing to a choice. Once you commit, jot down in one line why each of the other three options is wrong — that elimination habit is what turns a 60-percentile score into a 90-percentile score. MPSC's favourite trap on aptitude questions is to swap a single anchor word (a date, a place, a body, a ratio) so a mostly-right option becomes wrong.
Subject-specific tip
Tip: revise this question with the rest of the section on our subject-wise practice mode and pair the review with the relevant study guide to lock the concept into long-term memory.
MPSC prelims — the four-subject balance
The MPSC combined preliminary paper allots roughly equal weightage to Polity, Geography, History, Science, Economics, Current Affairs, Environment, Marathi grammar / English grammar and Aptitude. No single subject dominates, which means the optimal preparation strategy is to hit a floor of 60-percent accuracy across every subject before pushing any one to 90 percent. Aspirants who ignore Aptitude or Marathi grammar because they 'know the subject' consistently lose two to three marks on those sections and slip below the cut-off.
For every question you encounter on MPSC PYQ QUIZ, the recommended review loop is: attempt without looking at the answer; check the correct option; read the explanation; then read the 'Why this question matters' and 'How to attempt' sections below. That three-minute loop turns each PYQ into a mini-lesson and is why the majority of our top-percentile users solve every PYQ at least twice.
The strongest signal that you are ready for MPSC prelims is not the number of PYQs solved but the accuracy on unseen mock questions. Practise unseen items from our topic-wise section between full-length mocks to stress-test whether the concepts have really moved into long-term memory.
