Statement Assumptions

Key Concepts

# Concept Explanation
1 What is an Assumption? An unstated, logically necessary premise that must be true for the statement to hold.
2 Standard Format Statement → Assumption → Conclusion. Assumption bridges the gap.
3 Positive vs Negative Positive assumption supports; negative assumption contradicts. Reject negative.
4 Too Obvious If the assumption merely repeats the statement, it is not an assumption.
5 Extreme Words “Only”, “Always”, “Never”, “All” usually make assumptions invalid.
6 Chain Assumption If assumption needs another assumption, it is not the correct one.
7 Venn-Trick Draw a quick Venn/arrow diagram to visualise scope & direction.
8 3-Step Elimination 1. Reject contradicting. 2. Reject obvious. 3. Pick the must-be-true.

15 Practice MCQs

  1. Statement: “Use R-Wallet, the new digital ticketing app of Railways, for hassle-free booking.” Assumption I: People want hassle-free booking.
    Assumption II: R-Wallet is faster than traditional methods.
    A. Only I implicit B. Only II implicit C. Both I & II D. Neither
    Answer: A
    Solution: The appeal is based on the desire for convenience; speed is not claimed.
    Shortcut: Appeal-word “hassle-free” ⇒ desire assumption (I) only.
    Tag: Appeal-word

  2. Statement: “The factory has introduced an 8-hour shift to reduce worker fatigue.” I. Longer shifts cause fatigue.
    II. 8-hour shift will reduce fatigue.
    A. Only I B. Only II C. Both D. Neither
    Answer: C
    Solution: Both are necessary; if longer shifts did not cause fatigue, no need to reduce them; if 8-hour does not reduce fatigue, action is useless.
    Shortcut: Cause-effect statements usually assume both cause and remedy efficacy.
    Tag: Cause-effect

Speed Tricks

Situation Shortcut Example
“Only X” appears Assume non-X is invalid; don’t assume X is available to all. Q.5 above
Warning/Prohibition Assume (i) threat exists, (ii) penalty deters. Q.3
Advertisement Assume customer values claimed benefit; never assume competitor is bad. Q.12
Cause-Effect policy Assume both cause exists & proposed action will work. Q.2, Q.6
Extreme words (always/never/all/only) in assumption option 90 % mark invalid; pick only if unavoidably necessary. Q.11

Quick Revision

Point Detail
1 Assumption = unstated must-be-true premise.
2 If assumption is explicit in statement → reject.
3 Negative assumption → always reject.
4 “Only” in statement ⇒ reverse is invalid; “only” in assumption ⇒ likely invalid.
5 Chain assumption (assumption needs another assumption) → invalid.
6 Appeal/Advisory ⇒ assume desire/need exists.
7 Warning ⇒ assume threat exists.
8 Remedy ⇒ assume problem exists & remedy works.
9 Technology ⇒ assume feasibility, not user ownership.
10 3-step elimination: Contradictory → Obvious → Must-be-true; saves 20 s per Q.
