A.40

B.48

C.36

D.42

Explanation: The differences increase by 2 each time: +4, +6, +8, +10, so the next difference is +12, giving 30+12=42. Equivalently, terms follow n(n+1) for n=1..6. Number-series items are core DSSSB reasoning.

9If ROSE is coded as 6821 and CHAIR is coded as 73456, how is SEARCH coded with the same letter key?

A.214673

B.216473

C.214763

D.214637

Explanation: From ROSE→6821 and CHAIR→73456, letter codes are S=2, E=1, A=4, R=6, C=7, H=3. SEARCH maps to 2-1-4-6-7-3 = 214673. Fixed-key coding-decoding is standard DSSSB verbal reasoning.

10Pointing to a boy, a woman says, 'He is the son of my mother's only daughter.' How is the boy related to the woman?

A.Brother

B.Son

C.Nephew

About the DSSSB JE Exam Exam

The DSSSB Junior Engineer Examination recruits Junior Engineers (commonly Civil) for departments of the Government of NCT of Delhi such as Delhi Jal Board and New Delhi Municipal Council. The current One Tier Technical CBT combines a 100-mark general aptitude/language Section A with a double-weighted 200-mark Civil technical Section B. This free practice bank offers 100 MCQs spanning Section A skills and diploma-level Civil topics drawn from DSSSB indicative syllabi (building materials, surveying, soil/foundation, hydraulics/irrigation, concrete/RCC, structures, steel, environmental, transportation, estimating and applied basics).

Assessment

One Tier Technical (I-T-T) computer-based MCQ examination for recent Junior Engineer (Civil) recruitments: Section A — General Awareness, Reasoning, Numerical Ability, Hindi and English (20 marks each; 100 questions, 100 marks); Section B — discipline-specific Civil Engineering application questions (100 questions, 200 marks). Total 200 questions, 300 marks, 3 hours. Negative marking 0.25 / 0.50 for wrong 1-mark / 2-mark answers. Older DSSSB schemes listed some JE posts under Two-Tier Technical; always confirm the scheme printed in your advertisement.

Time Limit

3 hours (180 minutes) for One Tier Technical JE sittings used in recent Civil JE cycles (e.g. Advt. No. 01/2026).

Passing Score

Minimum qualifying marks (cumulative, with Section B domain minimum in One Tier Technical): General/EWS 40%, OBC (Delhi) 35%, SC/ST/PwBD 30%; Ex-Servicemen 5% relaxation in category subject to minimum 30%. Merit list and department cut-offs decide final selection.

Exam Fee

Rs. 100 application fee for categories required to pay in recent DSSSB JE advertisements; women and SC/ST/PwBD/Ex-Servicemen are typically exempt. Pay only via the mode stated in the advertisement (commonly SBI e-pay). Confirm on the live notice. (Delhi Subordinate Services Selection Board (DSSSB))

DSSSB JE Exam Study Tips from Top Performers

1Treat Section B as double-weighted: every Civil technical mark is worth twice a Section A mark, so prioritise diploma-level Civil revision (RCC, materials, soil, surveying, hydraulics) before polishing language sections.

2Practise under a 3-hour clock with negative marking in mind — skipping doubtful 2-mark technical items can protect your score more than guessing.

3Drill IS 456 cover, W/C durability limits, Atterberg calculations, bearing/fore-bearing conversions and standard BM/SF results, which recur across DSSSB and related JE Civil papers.

Frequently Asked Questions

What is the DSSSB JE exam pattern for recent Junior Engineer (Civil) recruitments?

Recent JE (Civil) advertisements (e.g. Advt. No. 01/2026) use One Tier Technical CBT: 200 MCQs in 3 hours for 300 marks. Section A has 100 one-mark questions on GA, reasoning, numerical ability, Hindi and English (20 marks each). Section B has 100 two-mark Civil technical questions (200 marks). Negative marking is 0.25 for wrong 1-mark answers and 0.50 for wrong 2-mark answers.

What are the minimum qualifying marks for DSSSB JE?

In One Tier Technical scheme, mandatory minimums apply on cumulative marks (and on Section B domain): General/EWS 40%, OBC (Delhi) 35%, SC/ST/PwBD 30%. Ex-Servicemen receive 5% relaxation in their category subject to a minimum of 30%. Final appointment still depends on merit and vacancies.

Is this practice bank only Civil Engineering?

Yes. The free bank mirrors the common DSSSB JE Civil technical syllabus plus Section A general papers. If you are appearing for JE Electrical or Mechanical under a different post code, use the technical syllabus printed for that post; Section A skills still transfer.

How many questions are in this free practice set?

This bank has 100 multiple-choice questions weighted to the One Tier blueprint (about one-third Section A skills and two-thirds Civil Section B topics by mark share), with explanations for every option.
