1In the RRB Technician CBT, each correct answer carries 1 mark and each wrong answer attracts a deduction of 1/3 mark. A candidate answers 90 questions, getting 75 correct and 15 wrong. What is the candidate's net score?
A.70
B.75
C.65
D.60
Explanation: Marks for correct answers = 75 x 1 = 75. Penalty for wrong answers = 15 x (1/3) = 5. Net score = 75 - 5 = 70. Understanding negative marking helps you decide when guessing is worthwhile on the RRB Technician CBT.
2Evaluate using the BODMAS rule: 12 + 6 x (10 - 4) / 3.
A.24
B.36
C.12
D.30
Explanation: BODMAS order: brackets first, (10 - 4) = 6. Then 6 x 6 = 36, then 36 / 3 = 12, finally 12 + 12 = 24. The Mathematics section of the RRB Technician CBT relies heavily on correct order of operations.
3The HCF of two numbers is 6 and their LCM is 36. If one number is 12, what is the other number?
A.18
B.24
C.30
D.9
Explanation: For any two numbers, Product = HCF x LCM. So the product = 6 x 36 = 216. The other number = 216 / 12 = 18. This HCF-LCM product relationship is a frequently tested Mathematics shortcut.
4A shopkeeper marks an item 40% above cost and then gives a 25% discount on the marked price. What is his profit percentage?
A.5%
B.15%
C.10%
D.0%
Explanation: Let cost = 100. Marked price = 140. Selling price after 25% discount = 140 x 0.75 = 105. Profit = 105 - 100 = 5, so profit percentage = 5%. Successive markup and discount problems appear regularly in the Mathematics section.
5If 8 workers can complete a job in 15 days, how many days will 12 workers take to complete the same job, assuming equal efficiency?
A.10
B.12
C.9
D.20
Explanation: Total work = 8 x 15 = 120 worker-days. With 12 workers, days needed = 120 / 12 = 10 days. Time and work problems use the inverse relationship between number of workers and time taken.
6A train 150 m long travels at 54 km/h. How long does it take to completely cross a stationary pole?
A.10 seconds
B.15 seconds
C.9 seconds
D.12 seconds
Explanation: Convert speed: 54 km/h x (5/18) = 15 m/s. To cross a pole, the train covers its own length, 150 m. Time = 150 / 15 = 10 seconds. Train problems require converting km/h to m/s using the factor 5/18.
7What is the simple interest on Rs 8,000 at 5% per annum for 3 years?
A.Rs 1,200
B.Rs 1,500
C.Rs 1,000
D.Rs 800
Explanation: Simple interest = (Principal x Rate x Time) / 100 = (8000 x 5 x 3) / 100 = Rs 1,200. Simple and compound interest are standard scoring topics in the RRB Technician Mathematics section.
8The ratio of two numbers is 3:5 and their sum is 64. What is the larger number?
A.40
B.24
C.32
D.45
Explanation: Total parts = 3 + 5 = 8. Value of one part = 64 / 8 = 8. The larger number = 5 x 8 = 40. Ratio and proportion problems are solved by finding the value of a single part.
9Solve for x: 3x - 7 = 2x + 5.
A.12
B.2
C.-2
D.6
Explanation: Move variables to one side: 3x - 2x = 5 + 7, giving x = 12. Linear equations from the algebra portion of the syllabus reward careful transposition of terms.
10In a right-angled triangle the two perpendicular sides are 6 cm and 8 cm. What is the length of the hypotenuse?
A.10 cm
B.12 cm
C.14 cm
D.9 cm
Explanation: By the Pythagoras theorem, hypotenuse = sqrt(6^2 + 8^2) = sqrt(36 + 64) = sqrt(100) = 10 cm. The 6-8-10 set is a scaled Pythagorean triple frequently used in geometry questions.

RRB Technician Study Tips from Top Performers

1Lock in the subject-wise marks split for your post first — General Science (Grade III) or Basic Science & Engineering (Grade I Signal) carries the highest weight and is the biggest scoring opportunity.
2Master Class 10 Physics, Chemistry and Biology fundamentals; many General Science questions are direct factual or single-formula items.
3Practise Mathematics shortcuts for percentages, ratio, time-and-work and interest so you can solve quickly within the 90-minute limit.
4Drill reasoning patterns — series, coding-decoding, blood relations and syllogism — until they become near-instant recognitions.
5For Grade I Signal, treat Basics of Computers and MS Office as easy, high-yield marks and revise networking, OS and storage basics.
6Apply a negative-marking strategy: skip questions you cannot reasonably narrow down, since each wrong answer costs 1/3 mark.
7Take full-length timed mock CBTs and review by section to fix the weakest area before the actual exam.
