4
12
6
8
Two typists type 2 pages in 2 minutes => each typist types 1 page in 2 minutes (0.5 pages/min). To type 18 pages in 6 minutes, rate needed is 3 pages/min, so 3/0.5 = 6 typists. See .

600
360
720
420
This is the factorial sequence: n! for n=1,2,3,4,5,... so 6! = 720. Factorials often appear in advanced numerical IQ questions. See .
John is taller than Peter. Peter is taller than Mary. Mary is taller than Lucy. Who is the second tallest?
Lucy
Mary
Peter
John
Ordering by height gives John > Peter > Mary > Lucy, so Peter is the second tallest. Transitive ordering is a common reasoning skill. See .
Tree is to forest as star is to __?
galaxy
solar system
constellation
nebula
A forest is a group of trees, and a constellation is a recognized grouping of stars. Analogies testing these relationships are standard in high-level IQ tests. See .
Which 3D shape has eight faces?
dodecahedron
octahedron
cube
icosahedron
An octahedron has eight faces. Cubes have six, dodecahedrons have twelve, and icosahedrons have twenty. Spatial reasoning questions frequently include polyhedra. See .
In the classic cryptarithm SEND + MORE = MONEY, what digit does M represent?
8
1
0
9
Solving the cryptarithm yields M = 1 as the only value that makes the sum work digit-by-digit. Cryptarithms test logical deduction and arithmetic. See .
If five machines take five minutes to make five gadgets, how long will 100 machines take to make 100 gadgets?
5 minutes
10 minutes
20 minutes
100 minutes
Each gadget takes one machine five minutes. Running 100 machines in parallel to produce 100 gadgets still takes five minutes. Rate and work-distribution puzzles are frequent in IQ exams. See .
What is the 7th prime number?
17
13
15
19
Primes: 2, 3, 5, 7, 11, 13, 17 - the 7th prime is 17. Recognizing prime sequences is a common IQ-test skill. See .
Which word is the odd one out: apple, peach, carrot, banana?
apple
banana

Cheat Sheet

  1. Mastering Pattern Recognition -

    Raven's Progressive Matrices are the gold standard for pattern recognition in high iq quiz assessments (Source: Psych.org). Practice by identifying the rule transforming one shape into the next - for example, rotating a square 90° while adding a dot in each step. A helpful mnemonic is "Observe, Hypothesize, Test" to streamline your approach to each matrix.

  2. Sharpening Logical Deduction -

    Logical syllogisms and conditional reasoning questions often appear in free IQ tests (Source: APA Journals). Break down statements into "if - then" components, such as "If all A are B and C is A, then C is B," to validate conclusions. Use a simple flowchart or truth table on scratch paper to keep track of premises and outcomes.

  3. Building Verbal Analogy Skills -

    Verbal analogies measure your ability to recognize relationships between words, a common section in online IQ quiz platforms (Source: ETS). Practice classic analogies like "Bird is to Nest as Bee is to Hive" and create your own pairs to deepen understanding. Mnemonic trick: remember "A→B means relationship R" and label R explicitly (e.g., habitat, function, part - whole).

  4. Cracking Number Series -

    Numerical sequences test your quantitative reasoning in many IQ test practice banks (Source: Mensa Foundation). Familiarize yourself with arithmetic (an = a1 + (n - 1)d) and geometric series (an = a1·r^(n - 1)) formulas to predict the next term. A quick tip: check for multiple patterns simultaneously - differences, ratios, or alternating operations.

  5. Enhancing Spatial Visualization -

    Spatial tasks appear in both psychometric exams and high iq quiz challenges to assess mental rotation and 3D manipulation (Source: Harvard Vision Lab). Use paper folding or imaginary rotation exercises - visualize how a cube with colored faces looks after a 180° turn. Recall "Right”Hand Rule" for consistent orientation when solving rotation items.
