RRB Technician recruitment is issued by the Railway Recruitment Boards through a Centralised Employment Notice (CEN), covering two categories — Technician Grade I (Signal) and Technician Grade III — each with its own eligibility. Selection runs through a single-stage Computer-Based Test (CBT), followed by document verification and a medical examination.

Exam Pattern

Conducting body: Railway Recruitment Boards (RRBs), through a Centralised Employment Notice (CEN). The Technician posts are advertised in two categories — Technician Grade I Signal and Technician Grade III — with different eligibility (Grade I typically needs an engineering diploma/degree in a relevant branch; Grade III typically needs an ITI / relevant qualification). Selection: a single-stage Computer-Based Test (CBT), followed by Document Verification and Medical Examination.

CBT: 100 questions, 100 marks, 90 minutes (120 minutes for eligible PwBD candidates with a scribe). Negative marking: one-third (1/3) mark for each wrong answer. The section split differs by grade:

Technician Grade I (Signal): General Awareness 10, General Intelligence & Reasoning 15, Basics of Computers & Applications 20, Mathematics 20, Basic Science & Engineering 35.
Technician Grade III: Mathematics 25, General Intelligence & Reasoning 25, General Science 40, General Awareness (current affairs) 10.

Normalisation of marks is applied when the exam is held in multiple shifts. This matches the recently-used RRB Technician CEN pattern; the exact split, qualifying marks and stages can change between CENs, so always confirm against the specific Technician notification on rrbapply.gov.in.

LCM & HCF
Rs 720 is divided between two people in the ratio 3:5. What is the smaller share?
- A 240
- B 270
- C 300
- D 450
Show answer

B — 270

Total parts = 3+5 = 8. Each part = 720/8 = 90. The smaller share = 3 x 90 = 270.

Ratio & Proportion
A can finish a job in 12 days, and B can finish the same job in 18 days. Working together, how many days will they take?
- A 7.2 days
- B 6 days
- C 8 days
- D 9 days
Show answer

A — 7.2 days

A's rate = 1/12 per day, B's rate = 1/18 per day. Combined rate = 1/12 + 1/18 = 5/36 per day, so time = 36/5 = 7.2 days.

Time & Work
A car travels at 60 km/h. How much time will it take to cover 150 km?
- A 2 hours
- B 3 hours
- C 2.5 hours
- D 3.5 hours
Show answer

C — 2.5 hours

Time = Distance / Speed = 150/60 = 2.5 hours.

Time & Distance
Find the simple interest on Rs 5000 at 8% per annum for 3 years.
- A Rs 1000
- B Rs 1200
- C Rs 1100
- D Rs 1300
Show answer

B — Rs 1200

Simple Interest = (P x R x T)/100 = (5000 x 8 x 3)/100 = 1200.

Simple & Compound Interest
A shopkeeper buys an item for Rs 400 and sells it for Rs 460. What is the profit percentage?
- A 10%
- B 12%
- C 20%
- D 15%
Show answer

D — 15%

Profit = 460 - 400 = 60. Profit% = (60/400) x 100 = 15%.

Profit & Loss
What is the square root of 225?
- A 12
- B 18
- C 15
- D 25
Show answer

C — 15

15 x 15 = 225, so the square root of 225 is 15.

Square Roots

- A 5 hours
- B 7 hours
- C 8 hours
- D 6 hours
Show answer

D — 6 hours

A's rate = 1/10 per hour, B's rate = 1/15 per hour. Combined rate = 1/10 + 1/15 = 1/6 per hour, so time = 6 hours.

Pipes & Cisterns
Find the next number in the series: 2, 6, 12, 20, 30, ?
- A 36
- B 42
- C 40
- D 45
Show answer

B — 42

The differences between consecutive terms are 4, 6, 8, 10, 12 — each increasing by 2. So the next term is 30 + 12 = 42.

Alphabetical & Number Series
If CAT is coded as DBU, how will DOG be coded using the same rule?
- A EPI
- B FPH
- C EPH
- D EQH
Show answer

C — EPH

Each letter is shifted forward by one place: C->D, A->B, T->U. Applying the same rule to DOG: D->E, O->P, G->H, giving EPH.
