Eight analytical questions of the kind WILP asks — find-the-wrong-number series, statement & assumptions, syllogism, blood relations and coding-decoding. The first five are from Wipro placement papers; each has a worked explanation showing the fastest route.
Fill in the blank: 343, 729, ____, 2197, 3375
Find the missing numbers in the series: 9261, 32768, ____, 157464, 274625, ____
Find the wrong number in the series: 2, 6, 12, 20, 30, 40, 56
Statement: Cactus plants grow in deserts and require little water. Assumptions: I. All plants that grow in deserts require little water. II. Cactus plants might not grow in places with more water. Which assumption is implicit?
Statement: In an IPL match, RR made 100 runs in total; 65 of these were made by bowlers. Assumptions: I. 65% of the team consists of bowlers. II. The opening batsmen were bowlers. Which assumption is implicit?
Statements: 1. All men are women. 2. All women are kids. Conclusions: I. All men are kids. II. Some men are not kids. Which conclusion follows?
Pointing to Sarthak, Nidhi said, "His mother's brother is the father of my son Nikhil." How is Sarthak related to Nidhi?
In a certain code language, MANAGEMENT is written as TNEMEGANAM. How is QUALITY written in the same code?
Order of attempt inside the 20 minutes
Take the section in three sweeps. First the one-liners — series, coding-decoding, analogies, blood relations — which should cost 30–45 seconds each and bank 8–10 marks. Second the judgement questions — syllogisms, assumptions, conclusions — where a quick diagram settles the answer in about a minute. Last the puzzles — seating arrangements, data sufficiency, direction chains — which can consume three minutes each; start them only with the safe marks already in. Candidates who begin with the arrangement puzzle regularly leave six easy questions unread.
Method notes
- Wrong-number series: test n², n³, n(n+1) and n³ − 1 first, then constant difference, then alternating operations (×3, ÷2). The odd term is usually off by 1 or 2 — a sign that the setter tweaked a correct sequence.
- Assumptions: an assumption is what the speaker must take for granted for the statement to make sense. Any option that generalises ("all", "every") or adds new facts is not implicit.
- Syllogism: take statements as true even when absurd; draw two quick circles. "All A are B, all B are C" always gives "all A are C".
- Blood relations: start from the speaker and draw a tiny tree — never solve in your head.
- Coding-decoding: check reversal first, then a fixed shift, then position-sum patterns.
- Seating arrangements and data sufficiency take longest — attempt them last within the 20 minutes.
