Statements & Assumptions

Subject: Reasoning | Frequency: 1-2 questions per APPSC paper | Time: 45-60 sec/question

Introduction

An assumption is something taken for granted — an unstated belief that must be TRUE for the statement to make sense. You must determine which assumptions are implicit (hidden but necessary). The negation test is the single most reliable technique: negate the assumption; if the statement breaks, the assumption is implicit.

Core Method

1. Read the statement carefully — understand its full meaning
2. For each assumption, apply the Negation Test:
   • Negate the assumption
   • If the negated version makes the statement meaningless/invalid → assumption IS implicit
   • If the statement still works → assumption is NOT implicit
3. Check for overgeneralization — assumptions with "all", "only", "every" are usually NOT implicit
4. Check for reasonableness — implicit assumptions are moderate, not extreme

Special Rules

Worked Examples — Easy

Q1: Statement: "Please do not park vehicles near the gate." Assumptions: I. People may park near the gate. II. Only cars are parked near the gate.

• I: If no one parks there, no need for the sign → must be true (implicit)
• II: "Only cars" — too restrictive; statement says "vehicles" generally → not implicit
• Answer: Only I is implicit

Q2: Statement: "Read this book to improve your English." Assumptions: I. The book can help improve English. II. Reading is the only way to improve English.

• I: If the book couldn't help, the recommendation is meaningless → implicit
• II: "Only way" — overly absolute → not implicit
• Answer: Only I is implicit

Q3: Statement: "The company decided to give all employees a 10% raise." Assumptions: I. The company can afford the raise. II. All employees will work harder after the raise.

• I: If they can't afford it, the decision is irrational → implicit
• II: Future behavior prediction not necessary for the decision → not implicit
• Answer: Only I is implicit

Worked Examples — Medium

Q4: Statement: "If you want to lose weight, join our gym." Assumptions: I. Joining the gym helps in losing weight. II. Losing weight is desirable.

• I: Negation: "Gym doesn't help lose weight" → statement is meaningless → implicit
• II: The ad targets people who want to lose weight → assumes such people exist → implicit
• Answer: Both are implicit

Q5: Statement: "Coaching classes will start from Monday." Assumptions: I. Some students may join. II. Every student needs coaching.

• I: If no one joins, announcing is pointless → implicit
• II: "Every" — too absolute → not implicit
• Answer: Only I is implicit

Q6: Statement: "The best way to travel between Delhi and Mumbai is by flight." Assumptions: I. There are flights between Delhi and Mumbai. II. No other mode of travel exists.

• I: Negation: "No flights exist" → statement meaningless → implicit
• II: "Best way" does not mean "only way" → not implicit
• Answer: Only I is implicit

Worked Examples — Hard

Q7: Statement: "The principal decided to suspend all students found cheating." Assumptions: I. The principal has the authority to suspend. II. This will deter future cheating.

• I: If no authority, decision is invalid → implicit
• II: Deterrence is a possible motive but NOT necessary for enforcing rules → not implicit
• Answer: Only I is implicit

Q8: Statement: "The government increased tax on tobacco to discourage consumption." Assumptions: I. Increased tax will make tobacco more expensive. II. Higher price may reduce consumption.

• I: Tax increase → price increase is a direct economic fact → implicit
• II: If higher price wouldn't reduce consumption, the policy makes no sense → implicit
• Answer: Both are implicit

Q9: Statement: "Candidates with less than 60% marks need not apply." Assumptions: I. There are candidates with less than 60%. II. Marks percentage indicates candidate quality.

• I: If no such candidates exist, the warning is unnecessary → implicit
• II: Using marks as a filter implies they indicate quality → implicit
• Answer: Both are implicit

Shortcuts & Tricks

Common Mistakes

1. Confusing explicit with implicit — if the statement directly says it, it's not an assumption
2. Accepting overly strong assumptions — "all", "only", "every" in assumptions are red flags
3. Adding personal beliefs — your opinions don't matter; only the statement's logic counts
4. Missing the negation test — when unsure, always apply negation
5. Confusing assumption with conclusion — an assumption supports the statement; a conclusion follows from it

Exam Strategy

• Apply the negation test on every assumption — it's the single most reliable technique
• APPSC keeps difficulty at medium
• Time: 45-60 seconds per question
• Red flag: if an assumption contains "only", "all", "every", or "no one" — it's almost certainly NOT implicit
• Green flag: if an assumption contains "some", "may", "can" — it's likely implicit
• Negative marking: -0.333 — the negation test gives you high confidence

Practice Questions

1. "Walk carefully, the floor is wet." Assumption: Wet floors can cause slipping? → Implicit (negation test: if wet floors are safe, the warning is meaningless)
2. "Apply now for 50% scholarship." Assumption: Only 50% scholarship is available? → Not implicit (statement doesn't say "only")
3. "The train will be late today due to fog." Assumption: Fog can delay trains? → Implicit
4. "Enroll your child in our school for the best education." Assumption: All children who enroll will become toppers? → Not implicit ("all" + extreme claim)
5. "The company decided to shut down the loss-making unit." Assumption: The company has authority to shut down units? → Implicit
