General Intelligence and Reasoning flashcards for SSC CHSL (Combined Higher Secondary Level)

22 of 50 cards from the General Intelligence and Reasoning deck — real questions with worked answers.

1. In reasoning, what is an analogy?

   An analogy is a relationship of similarity between two pairs of items, where the relation that connects the first pair also connects the second pair (e.g., A is to B as C is to D).

2. What is a word (semantic) analogy?

   A word analogy tests the logical/meaning-based relationship between two words and asks you to find a pair sharing the same relationship (e.g., synonym, antonym, part-whole, cause-effect, worker-tool).

3. In the word analogy 'Doctor : Hospital :: Teacher : ?', what is the answer and the relationship?

   School. The relationship is 'worker : workplace'.

4. List four common relationship types used in word/semantic analogies.

   Synonym/antonym; part to whole; cause and effect; worker and tool/workplace; (also category-member, function, and degree of intensity).

5. What is a number analogy?

   A number analogy tests a mathematical relationship between numbers in one pair and asks you to identify a second pair following the same rule (e.g., square, cube, multiple, or arithmetic operation).

6. Solve the number analogy: $5 : 25 :: 8 : ?$

   $64$. The rule is squaring the first number: $5^{2}=25$, so $8^{2}=64$.

7. Solve the number analogy: $7 : 343 :: 4 : ?$

   $64$. The rule is cubing: $7^{3}=343$, so $4^{3}=64$.

8. What is a letter analogy and what is the main technique to solve it?

   A letter analogy uses relationships between letters or letter-groups; you solve it by converting letters to their alphabetical positions (A=1, ..., Z=26) and finding the shift/pattern between them.

9. State the alphabetical position values of A, M, N, and Z.

   $A=1$, $M=13$, $N=14$, $Z=26$.

10. Solve the letter analogy: AB : CD :: EF : ?

    GH. Each letter shifts forward by 2 positions ($A\to C$, $B\to D$, so $E\to G$, $F\to H$).

11. Solve the letter analogy: ACE : BDF :: MOQ : ?

    NPR. Each letter moves forward by 1 position ($M\to N$, $O\to P$, $Q\to R$).

12. What is a mixed analogy?

    A mixed analogy combines more than one element type (letters with numbers, or words with numbers) in each pair, requiring you to track both relationships simultaneously.

13. In 'choosing the analogous pair' questions, what is the task?

    You are given a sample pair and must select, from the options, the pair whose internal relationship is identical to the relationship in the sample pair.

14. What is classification (odd-one-out) in reasoning?

    Classification asks you to identify the one item from a group that does NOT share the common property or relationship that the others have in common.

15. What is the general strategy for solving any classification (odd-one-out) problem?

    Find the common property (category, mathematical rule, or letter pattern) shared by most items; the item that fails to fit that common rule is the odd one out.

16. What is word classification?

    Word classification groups words by a shared category or feature (e.g., all are birds, metals, or tools) and asks for the word that does not belong to that category.

17. In the set Rose, Lotus, Marigold, Mango — which is the odd one out and why?

    Mango. Rose, Lotus, and Marigold are flowers, while Mango is a fruit.

18. What is number classification?

    Number classification groups numbers by a shared mathematical property (e.g., all primes, all perfect squares, all multiples) and asks which number breaks the pattern.

19. In the set $9, 16, 25, 30, 36$, which number is the odd one out?

    $30$. All others are perfect squares ($3^{2},4^{2},5^{2},6^{2}$), but $30$ is not.

20. Identify the odd one out: $3, 5, 7, 9, 11$.

    $9$. The others are prime numbers, but $9 = 3\times 3$ is composite.

21. What is letter classification?

    Letter classification groups letter clusters by a shared pattern (e.g., same gap between letters, all vowels/consonants) and asks which cluster does not follow the pattern.

22. Identify the odd one out: BD, FH, JL, MN.

    MN. In BD, FH, JL the two letters have a gap of 2 (one letter skipped), but in MN they are consecutive (gap of 1).
