SSC CHSL (Combined Higher Secondary Level) General Intelligence and Reasoning flashcards — 50 questions with 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.

  1. 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.

  2. 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).

  3. What is mixed classification?

    Mixed classification asks you to find the odd one out from groups that combine letters and numbers, where a consistent letter-number relationship defines the group.

  4. What is a series in reasoning?

    A series is an ordered sequence of numbers, letters, or both that follows a definite rule; you must find the rule to supply a missing term or detect a wrong term.

  5. What is a number series?

    A number series is a sequence of numbers arranged by a pattern such as addition, subtraction, multiplication, division, squares, cubes, or a combination of these.

  6. Find the next term: $2, 6, 12, 20, 30, ?$

    $42$. Differences increase as $4,6,8,10,12$, so $30+12=42$ (terms are $n(n+1)$).

  7. Find the next term: $1, 4, 9, 16, 25, ?$

    $36$. The series is consecutive perfect squares $n^{2}$, so the next is $6^{2}=36$.

  8. Find the next term: $3, 6, 12, 24, ?$

    $48$. Each term is multiplied by $2$, so $24\times 2 = 48$.

  9. Find the missing term: $1, 1, 2, 3, 5, 8, ?$

    $13$. It is the Fibonacci series; each term equals the sum of the two preceding terms ($5+8=13$).

  10. What is an alphabet series?

    An alphabet series is a sequence of letters following a fixed rule, usually a constant or varying gap (skip) in alphabetical positions.

  11. Find the next letter: A, C, E, G, ?

    I. The pattern skips one letter each time (gap of $+2$ positions): $A,C,E,G,I$.

  12. Find the next letter: A, B, D, G, K, ?

    P. The gaps increase as $+1,+2,+3,+4,+5$, so $K(11)+5 = 16 = P$.

  13. What is an alphanumeric series?

    An alphanumeric series mixes letters, numbers, and sometimes symbols, requiring you to track separate patterns for the letters and the numbers.

  14. Find the next term: $A1, C3, E5, G7, ?$

    $I9$. Letters skip one each time ($A,C,E,G,I$) and numbers increase by $2$ ($1,3,5,7,9$).

  15. What does a 'missing term' series question ask?

    It asks you to identify the rule of the sequence and supply the term that has been left blank within or at the end of the series.

  16. What does a 'wrong term' series question ask, and how do you solve it?

    It asks which single term breaks the otherwise consistent pattern; you find the rule from the correct terms and identify the one value that does not fit.

  17. Find the wrong term: $2, 4, 8, 16, 30, 64$.

    $30$. The series doubles each time ($\times 2$), so the term after $16$ should be $32$, not $30$.

  18. What is coding-decoding in reasoning?

    Coding-decoding is the process of encrypting a word/message using a defined rule (the code) and then applying that same rule to decode or encode a new word.

  19. What is letter-shifting coding?

    Letter-shifting coding replaces each letter by another a fixed number of positions forward or backward in the alphabet (e.g., +1, +2, or reverse).

  20. In a +1 letter-shift code, how is 'CAT' written?

    DBU. Each letter moves one position forward: $C\to D$, $A\to B$, $T\to U$.

  21. What is opposite (reverse) letter coding, and what is the complement of any letter's position?

    Each letter is replaced by its opposite from the other end of the alphabet; the opposite of a letter at position $n$ is at position $27-n$ (e.g., $A\leftrightarrow Z$, $B\leftrightarrow Y$).

  22. Using opposite-letter coding ($27-n$), what is the code for 'DOG'?

    WLT. $D(4)\to W(23)$, $O(15)\to L(12)$, $G(7)\to T(20)$, since each uses $27-n$.

  23. What is number-based coding?

    Number-based coding assigns numbers to letters or words according to a rule (such as alphabetical position, position plus a constant, or a derived value) for encoding/decoding.

  24. If letters are coded by their alphabetical positions, what is the code for 'BAD'?

    $2,1,4$. Using $A=1$, $B=2$, $D=4$, so 'BAD' is coded as $2\text{-}1\text{-}4$.

  25. What is substitution coding?

    Substitution coding replaces real words with other given words (e.g., 'sky' is called 'blue'); you answer a question by using the substituted term instead of the actual one.

  26. In substitution coding, if 'water' is called 'air' and 'air' is called 'sky', in which do fish live (as named in this code)?

    Air. Fish live in water, but water is called 'air', so the coded answer is 'air'.

  27. What is conditional coding (matrix/letter-number coding)?

    Conditional coding gives digits/letters with a set of conditions (rules) that modify how certain elements are coded based on their position or neighbours (e.g., first or last element conditions).

  28. In coding-decoding, why is comparing two given coded words often the fastest method?

    Comparing two or more code-word pairs lets you find common letters mapped to common code symbols, revealing the substitution for individual letters even without an explicit shift rule.

  29. In letter-shift coding, how do you handle a shift that goes past Z?

    You wrap around to the start of the alphabet (treat it as cyclic mod 26), so after $Z$ the next letter is $A$ (e.g., $Z$ with $+1$ becomes $A$).

  30. Decode 'URZ' if it was made by a +3 forward letter-shift on the original word.

    ROW. Reverse the shift by moving each letter 3 positions back: $U\to R$, $R\to O$, $Z\to W$.
