A full-length IBPS RRB Office Assistant (RRB Clerk) Mains mock in the exact exam pattern — 200 questions for 200 marks across Reasoning, Computer Knowledge, General Awareness, English Language and Numerical Ability, on a single composite 120-minute clock. Sections are weighted as on the real paper, so Reasoning and Numerical Ability are worth more per question than Computer Knowledge. Every question carries a worked solution, and your result breaks performance down by section and by topic.
The real exam interfaceThe same question palette, Save & Next, Mark for Review and Clear Response as the exam-day software.
A server clockThe countdown runs on the server, so closing the tab or losing connection does not buy you extra minutes.
Real marking, negative includedWrong answers cost marks at the exam rate. Unattempted questions never do.

Sample questions
One question from each section of this paper, with the worked solution. The answers stay
hidden until you ask for them.
ReasoningSyllogism
In the question below, two statements are followed by two conclusions. Take the statements to be true even if they seem to disagree with commonly known facts, and decide which conclusion logically follows.
Statements:
All pens are books.
All books are papers.
Conclusions:
I. All pens are papers.
II. Some papers are pens.
AOnly conclusion I follows
BOnly conclusion II follows
CBoth conclusions I and II follow
DNeither conclusion follows
Show answer & solutionHide answer & solution
Correct answer:
C. Both conclusions I and II follow
Two universal statements chained together carry the chain through: pens sit inside books, and books sit inside papers, so pens sit inside papers.
Conclusion I follows directly.
Conclusion II is the converse of I. If every pen is a paper, then the pens themselves are papers that are pens — so some papers are pens. A universal affirmative always yields its particular converse.
Both follow.
Computer KnowledgeComputer Fundamentals
Which part of a computer is described as its 'brain', carrying out the instructions of a program?
ACPU
BRAM
CHard disk
DMonitor
Show answer & solutionHide answer & solution
Correct answer:
A. CPU
The Central Processing Unit (CPU) fetches, decodes and executes the instructions that make up a program, which is why it is commonly called the brain of the computer.
RAM holds data and instructions while they are in use but does not act on them. The hard disk stores data when the power is off, and the monitor only displays output.
The CPU itself is usually divided into the arithmetic logic unit, the control unit and a set of registers.
General AwarenessBanking Awareness
In banking, what does the abbreviation 'CRR' stand for?
ACredit Reserve Ratio
BCash Reserve Ratio
CCash Retention Rate
DCentral Reserve Ratio
Show answer & solutionHide answer & solution
Correct answer:
B. Cash Reserve Ratio
CRR stands for Cash Reserve Ratio.
It is the proportion of a bank's net demand and time liabilities that must be kept as cash with the Reserve Bank of India. The bank earns no interest on this amount.
Raising the CRR takes money out of the banking system and tightens liquidity; lowering it releases funds for lending. It should not be confused with the SLR, which may be held in cash, gold or approved securities and is retained by the bank itself.
English LanguageFill in the Blanks
The sentence below has two blanks. Choose the pair of words that fits both blanks so that the sentence is grammatically correct and makes sense.
The new officer was ___ in her manner but ___ in her decisions, which surprised those who had expected otherwise.
Aharsh, cruel
Bkind, weak
Cquiet, silent
Dgentle, firm
Show answer & solutionHide answer & solution
Correct answer:
D. gentle, firm
"But" requires the two qualities to pull against each other, and the closing clause confirms that the pairing was unexpected.
"Gentle, firm" is a genuine contrast — a mild manner concealing a hard edge — and is exactly the combination that would surprise people.
"Harsh, cruel" and "quiet, silent" are near-synonyms, so "but" has nothing to work with. "Kind, weak" is not really a contrast either; it is what people would have expected rather than a surprise.
Numerical AbilitySimplification and Approximation
What value should come in place of the question mark?
√1764 + √961 = ?
A71
B72
C73
D74
Show answer & solutionHide answer & solution
Correct answer:
C. 73
Both are perfect squares worth recognising on sight.
√1764 = 42, because 42² = 1764
√961 = 31, because 31² = 961
42 + 31 = 73.
A number ending in 4 has a root ending in 2 or 8, and 1764 sits between 40² = 1600 and 50² = 2500, which pins it to 42. The same test on 961: ending 1 means a root ending in 1 or 9, and it sits just under 32² = 1024, so 31.
