SSC JE is the exam for Junior Engineer posts (Civil, Mechanical and Electrical) in central government organisations such as CPWD, BRO, MES and the Central Water Commission. Selection has two stages, and both are objective computer-based tests — there is no descriptive paper under the current scheme. Paper-I mixes reasoning and general awareness with a first look at your engineering stream, while Paper-II goes deep into that same stream, so effort should go into both the common sections and your specific engineering subject.

Exam Pattern

SSC Junior Engineer (Civil, Mechanical & Electrical) is conducted by the Staff Selection Commission for JE posts in central organizations (CPWD, BRO, MES, Central Water Commission, Brahmaputra Board and more) — Group 'B' (Non-Gazetted), Pay Level-6 (₹35,400-1,12,400). Eligibility varies by post/organization: broadly a Degree OR a 3-year Diploma in the relevant engineering discipline (some posts, e.g. BRO, need 2 years' experience with the diploma route) — check the per-organization table in the notification. Age: generally up to 30 years (up to 32 for certain posts) with standard relaxations. Selection = two stages, and BOTH are objective computer-based tests — Paper-II is NOT descriptive under the current scheme. Paper-I: 200 questions/200 marks in 2 hours — General Intelligence & Reasoning 50/50, General Awareness 50/50, and your stream's General Engineering part 100/100; negative marking 0.25 per wrong answer. Paper-II: your engineering stream only, 100 questions/300 marks, 2 hours; negative marking 1 mark per wrong answer. Questions come in Hindi and English; engineering standard is approximately Diploma level; IS 456:2000 tables, steam tables and an on-screen scientific calculator are provided. Minimum qualifying marks: UR 30%, OBC/EWS 25%, others 20%. Fee ₹100 (women/SC/ST/PwBD/ESM exempt). Shortlisting for Paper-II is on normalized Paper-I marks; final merit = Paper-I + Paper-II combined (normalized). CONFIRMED against the official SSC Notice of Junior Engineer Examination, 2025 (F. No. HQ-C-3019/2/2025-C-3, published 30.06.2025 on ssc.gov.in).

- A 40
- B 42
- C 36
- D 44
Show answer

B — 42

Each term is n×(n+1): 1×2=2, 2×3=6, 3×4=12, 4×5=20, 5×6=30, so the next term is 6×7=42.

- A 180
- B 190
- C 200
- D 210
Show answer

C — 200

If x is the original number, 0.8x = 160, so x = 160 / 0.8 = 200.

arithmetical reasoning
Two numbers are in the ratio 3:5 and their sum is 96. Find the smaller number.
- A 30
- B 36
- C 40
- D 45
Show answer

B — 36

Let the numbers be 3x and 5x. Then 3x+5x=96, so 8x=96, x=12; the smaller number is 3×12=36.

The average of 5 numbers is 24. If one number is removed, the average of the remaining 4 numbers becomes 22. Find the removed number.
- A 28
- B 30
- C 32
- D 34
Show answer

C — 32

Sum of 5 numbers = 5×24=120. Sum of remaining 4 = 4×22=88. Removed number = 120−88=32.

- A 10%
- B 12%
- C 15%
- D 20%
Show answer

C — 15%

Profit = 920−800=120. Profit% = (120/800)×100 = 15%.

Show answer

B — ₹1,200

Simple Interest = (P×R×T)/100 = (5000×8×3)/100 = ₹1,200.

arithmetical reasoning
Simplify: 15 + 6 × 4 − 12 ÷ 3
- A 33
- B 35
- C 39
- D 31
Show answer

B — 35

By BODMAS: division and multiplication first — 6×4=24, 12÷3=4; then 15+24−4=35.

arithmetical computations
Hammer is related to Carpenter in the same way as Scalpel is related to ?
- A Butcher
- B Surgeon
- C Painter
- D Tailor
Show answer

B — Surgeon

A Carpenter's main tool is the Hammer; in the same way, a Surgeon's main tool is the Scalpel.

analogies
Choose the word that does not belong with the rest: Hammer, Chisel, Wrench, Timber
- A Hammer
- B Chisel
- C Wrench
- D Timber
Show answer

D — Timber

Hammer, Chisel and Wrench are all hand tools, while Timber is a building material, not a tool.

verbal and figure classification
Pointing to a photograph, a man said, 'She is the daughter of my grandfather's only son.' How is the woman related to the man?
- A Mother
- B Sister
- C Aunt
- D Cousin
Show answer

B — Sister

The man's grandfather's only son is the man's own father (since there is only one son). The daughter of the man's father is his sister.

relationship concepts
If the word CAT is coded as DBU (each letter moved one step forward in the alphabet), how is DOG coded in the same pattern?
- A EPH
- B EPG
- C DPH
- D EPI
Show answer

A — EPH

Moving each letter one step forward: D→E, O→P, G→H, giving the code EPH.
