  • 2. 

    What comes next in the sequence: 2, 4, 8, 16?

    • 18

    • 20

    • 32

    • 24

    Correct Answer
    A. 32
    Explanation
    The sequence in question doubles each preceding number to determine the next value. Starting with 2, each number is multiplied by 2 to arrive at the next: 2 times 2 equals 4, 4 times 2 equals 8, and so forth. By continuing this pattern, multiplying 16 by 2 yields 32, demonstrating a consistent doubling trend throughout the sequence. Understanding and applying this multiplication pattern is essential for solving the sequence logically and accurately.

    Rate this question:

  • 3. 

    What is the missing number in the sequence shown below? 1, 3, 6, 10, 15, __

    • 18

    • 21

    • 24

    • 27

    Correct Answer
    A. 21
    Explanation
    In this sequence, each number is the sum of all previous consecutive numbers plus an incrementally increasing integer. Starting from 1, the subsequent addition follows an increasing order by one each time. Thus, after 15 (which is the sum of 1+2+3+4+5), the next operation involves adding 6 to 15, resulting in 21. This progression highlights the ability to recognize and continue patterns involving cumulative and sequential additions.

    Rate this question:

  • 4. 

    Which number should come next in the pattern: 7, 10, 8, 11, 9, 12?

    • 10

    • 13

    • 11

    • 14

    Correct Answer
    A. 10
    Explanation
    This sequence exhibits a pattern of alternating operations: adding three and subtracting two. Beginning with the number 7, the sequence first increases by three to 10, then decreases by two to 8, continuing in this alternating fashion. Observing and continuing this pattern, we see that after reaching 12, the next operation according to the established pattern is to subtract two, resulting in 10.

    Rate this question:

  • 5. 

    If you rearrange the letters "CIFAIPC" you would have the name of a?

    • City

    • Animal

    • Ocean

    • Country

    Correct Answer
    A. Ocean
    Explanation
    Rearranging the letters "CIFAIPC" gives you "PACIFIC," which is the name of an ocean. The Pacific Ocean is the largest and deepest ocean on Earth, covering more than 63 million square miles. It is known for its vast expanse and significant influence on the world's climate and weather patterns. The name "Pacific" was given by the explorer Ferdinand Magellan, meaning "peaceful sea" in Portuguese.

    Rate this question:

  • 6. 

    If all Bloops are Razzies and all Razzies are Lazzies, all Bloops are definitely Lazzies?

    • True

    • False

    • Neither

    • Both

    Correct Answer
    A. True
    Explanation
    This logical deduction question involves understanding the transitive property in logic. If all Bloops are Razzies and all Razzies are Lazzies, then logically, all Bloops must also be Lazzies. This question tests the ability to follow logical connections and the application of logical reasoning to reach a conclusion based on given premises.

    Rate this question:

  • 7. 

    You see a ship filled with people, yet there isn’t a single person on board. How is this possible?

    • The ship is abandoned.

    • Everyone is a couple.

    • The ship is haunted.

    • The ship is sinking.

    Correct Answer
    A. Everyone is a couple.
    Explanation
    This riddle plays on the meaning of the word “single.” When it states that there isn’t a single person on board, it doesn’t mean the ship is empty. Instead, it implies that everyone on board is married, hence not "single." This question tests lateral thinking and the ability to recognize double meanings in words. Trick questions like this challenge conventional reasoning and encourage creative problem-solving. Being able to think outside the box is a valuable skill in IQ tests and real-life problem-solving situations.

    Rate this question:

  • 8. 

    Mary, who is sixteen years old, is four times as old as her brother. How old will she be when she is twice as old as her brother?

    • 20

    • 24

    • 22

    • 26

    Correct Answer
    A. 24
    Explanation
    Mary's age is a function of her brother’s age, set at four times his current age, making him 4 years old. The scenario posits that Mary will be twice her brother's age at some future point. Calculating forward, Mary will reach this milestone when her brother is 12 years old, at which time Mary will be 24 years old. This question involves basic arithmetic and understanding ratios and their implications over time.

    Rate this question:

  • 9. 

    John’s mother has three children: April, May, and what’s the name of the third child?

    • June

    • July

    • John

    • Sarah

    Correct Answer
    A. John
    Explanation
    This question is another example of a simple logic puzzle that tricks test-takers into overthinking. The sentence already gives the answer when it states "John’s mother has three children." The names of the first two children are April and May, but the third child's name is directly mentioned in the question—John. This problem is designed to test how well you pay attention to details and process information quickly without being distracted by misleading patterns. It emphasizes the importance of careful reading and avoiding assumptions.

    Rate this question:

  • 10. 

    If two's company and three's a crowd, what are four and five?

    • 9

    • 10

    • 11

    • 12

    Correct Answer
    A. 9
    Explanation
    This question is based on an idiomatic expression that plays with the numerical aspect of common phrases. Extending the phrase "two's company, three's a crowd" to include four and five as nine in a playful way involves mathematical humor, blending language with numerical logic to create a whimsical, yet logical, conclusion.

    Rate this question:

  • 11. 

    18, 20, 24, 32, ?

    • 48

    • 44 

    • 42 

    • 40

    Correct Answer
    A. 48
    Explanation
    The pattern in this sequence involves adding increasing even numbers to the previous term:
    18 + 2 = 20
    20 + 4 = 24
    24 + 8 = 32
    32 + 16 = 48

    Rate this question:

  • 12. 

    Which one of the five choices makes the best comparison? Finger is to Hand as Leaf is to?

    • Twig

    • Tree

    • Branch

    • Blossom

    Correct Answer
    A. Branch
    Explanation
    Comparing a leaf to a branch as one would a finger to a hand illustrates the concept of part-to-whole relationships in analogies. Just as a finger is part of a hand, a leaf is part of a branch. Each analogy uses a simple comparison to show how smaller components form part of larger structures in both biology and everyday observations.

    Rate this question:

  • 13. 

    Which one of the numbers does not belong in the following series: 2 - 3 - 6 - 7 - 8 - 14 - 15 - 30?

    • 8

    • 15

    • 30

    • 3

    Correct Answer
    A. 8
    Explanation
    The series typically doubles a number and adds one to establish the next in sequence, except for the number 8, which anomalously does not follow this pattern, making it the outlier. Recognizing this break in the pattern involves identifying the rule governing the sequence and noting where it fails to apply, a common type of pattern recognition problem in sequences.

    Rate this question:

  • 14. 

    If you rearrange the letters "LNGEDNA" you have the name of a:

    • River

    • State

    • City

    • Country

    Correct Answer
    A. Country
    Explanation
    The letters "LNGEDNA" can be rearranged to spell "ENGLAND," which is a country in the United Kingdom. This type of puzzle involves anagramming, where the letters of a word or phrase are rearranged to form another word or phrase. In this case, the scrambled letters represent a geographical location, specifically a country, making "Country" the correct category among the options provided (River, State, City, Country).

    Rate this question:

  • 15. 

    A farmer has 17 cows, all but 9 run away. How many cows does the farmer have left?

    • 8

    • 9

    • 7

    • 10

    Correct Answer
    A. 9
    Explanation
    This question plays on wording rather than arithmetic. The phrase "all but 9 run away" means that out of 17 cows, every cow except 9 has left. This directly tells us that the number of cows remaining is 9. Many test-takers misinterpret the phrase and try to perform an unnecessary subtraction. This type of problem tests logical comprehension and attention to detail rather than mathematical skills. Ensuring careful reading of the question is crucial when answering such trick-based IQ puzzles.

    Rate this question:

  • 16. 

    If you write all the numbers from 300 to 400, how many times do you write the number 3?

    • 100

    • 110

    • 120

    • 130

    Correct Answer
    A. 120
    Explanation
    Counting the occurrence of the digit '3' from 300 to 400 involves recognizing each instance within the hundreds, tens, and units place. In this range, every number in the hundreds contains at least one '3,' and the numbers 330 to 339 contain two '3's each. This question tests numerical pattern recognition and counting skills within a defined numerical range.

    Rate this question:

  • 17. 

    A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost?

    • $0.10

    • $0.05

    • $0.15

    • $0.01

    Correct Answer
    A. $0.05
    Explanation
    This is a classic IQ test question that tricks people into giving an intuitive but incorrect answer. Many assume the ball costs $0.10, but that would make the bat $1.00 more than that, which results in a total of $1.20, not $1.10. To solve it correctly, let’s say the ball costs X dollars. The bat is then (X + 1.00) dollars. So, the equation becomes:
    X + (X + 1.00) = 1.10
    2X + 1.00 = 1.10
    2X = 0.10
    X = 0.05
    Thus, the ball costs $0.05, and the bat costs $1.05, making the total $1.10. This problem tests the ability to resist intuitive errors and apply algebraic thinking.

    Rate this question:

  • 18. 

    If you divide 30 by half and add ten, what do you get?

    • 25

    • 50

    • 70

    • 100

    A. 70
  • 19. 

    A clock shows 3:15. What is the angle between the hour and minute hands?

    • 0°

    • 7.5°

    • 15°

    • 30°

    Correct Answer
    A. 7.5°
    Explanation
    At 3:15, the minute hand is at the 3-hour mark (pointing at 15 minutes), while the hour hand has moved slightly past 3. Each hour on a clock represents 30° (since 360° is divided into 12 hours). By 3:00, the hour hand is at 90°, but at 3:15, it has moved a quarter of the way toward 4. Since each hour mark accounts for 30°, the hour hand moves 7.5° every 15 minutes. The angle difference between the hour and minute hand at 3:15 is 7.5°. This problem requires both an understanding of geometry and analytical thinking.

    Rate this question:

  • 20. 

    Which figure fits into the missing slot?

    • Triangle

    • Square

    • Circle

    • Hexagon

    Correct Answer
    A. Triangle
    Explanation
    Assuming a logical progression or rotation among shapes, identifying the correct shape involves understanding spatial relationships and patterns within a set of options. This type of question tests geometric recognition and the ability to predict the next item in a visual sequence.
