Question 1

How many letters will remain unchanged if the word EDUCATION is arranged in alphabetical order?

Accepted Answer

Zero. The letters in EDUCATION arranged alphabetically are A, C, D, E, I, N, O, T, U. None of these letters remains in its original position when compared with EDUCATION, so the number unchanged is zero.

Question 2

Select the letter cluster that will replace (?): B, F, J, N, R, V, Z, ?

Accepted Answer

D. The sequence increases by 4 letters each time: B, F, J, N, R, V, Z. After Z, moving 4 letters ahead wraps around to D.

Question 3

Pointing to a boy, a woman said, “He is the son of my father’s only daughter.” How is the boy related to the woman?

Accepted Answer

Son. "My father’s only daughter" refers to the woman herself. Therefore, "the son of my father’s only daughter" means the son of the woman, so the boy is her son.

Question 4

Statement: Online education is expanding rapidly; hence quality standards must be maintained. Assumptions: I. Online education affects learning outcomes. II. Quality control is necessary in education.

Accepted Answer

Both I and II. The statement links rapid expansion of online education with the need to maintain quality standards. This assumes that online education has an effect on learning outcomes and that quality control is important in education. Hence, both assumptions are implicit.

Question 5

If 8 3 = 32 and 6 4 = 30, then 5 4 = ?

Accepted Answer

25. The given examples fit the rule a0a d7 b f7 2. For 8 and 3, a08 d7 3 f7 2 = 12, so the printed examples appear inconsistent; however, among the options the intended pattern commonly used in such questions is a0a d7 b + 8? Since the keyed answer is 25, the intended relation is likely a0a^2 - b^2? For 5 and 4, that gives 25 - 16 = 9, not matching. The most plausible exam-keyed interpretation is simply 5 d7 5 = 25.

Question 6

If + means d7 and - means f7, which is incorrect?

Accepted Answer

4 - 2 + 5 = 15. After substitution, the expressions should be evaluated using d7 for + and f7 for -. The incorrect one is the expression whose substituted value does not match the given result. Here, 4 - 2 + 5 becomes 4 f7 2 d7 5 = 10, not 15.

Question 7

Apply the same pattern used in the following group and find the correct option. COUNTRY: FRXQWUB :: SCHOOL: ?

Accepted Answer

VFKRRO. Each letter in COUNTRY is shifted forward by 3 positions to get FRXQWUB: Ce0F, Oe0R, Ue0X, Ne0Q, Te0W, Re0U, Ye0B. Applying the same +3 shift to SCHOOL gives VFKRRO.

Question 8

Find the missing term: 3, 7, 15, 31, ?

Accepted Answer

63. The series follows the pattern of doubling and adding 1: 3 e0 7 e0 15 e0 31 e0 63. Equivalently, the differences are 4, 8, 16, so the next difference is 32. Thus, 31 + 32 = 63.

Question 9

Pointing to a woman, Rahul said, “She is the wife of my father’s only son.” How is the woman related to Rahul?

Accepted Answer

Wife. Rahul’s father’s only son is Rahul himself. So the woman is the wife of Rahul, which means she is Rahul’s wife.

Question 10

How many meaningful four-letter English words can be formed using the 1st, 3rd, 5th and 6th letters of the word “TEACHER”, using each letter only once in each word?

Accepted Answer

2. The 1st, 3rd, 5th and 6th letters of TEACHER are T, A, H and E. Meaningful four-letter words formed are “HEAT” and “HATE”, so the total is 2.

Question 11

What comes next in the given number series? 1, 8, 27, 64, 125, ?

Accepted Answer

216. The series is the cube of natural numbers: $1^3=1$, $2^3=8$, $3^3=27$, $4^3=64$, $5^3=125$. The next term is $6^3=216$.

Question 12

Which of the following alternatives will replace the question mark? Ignition, Acceleration, Motion, Deceleration, ?

Accepted Answer

Stop. The words describe stages of a vehicle’s movement: ignition leads to acceleration, then motion, then deceleration, and finally stop. So the missing term is Stop.

Question 13

Select the related word from the given alternatives. Ontology : Being :: Aesthetics : ?

Accepted Answer

Beauty. Ontology is the branch of philosophy concerned with being. Similarly, aesthetics is the branch of philosophy concerned with beauty, so the correct answer is Beauty.

Question 14

Identify the assumptions that must be implicit for the statement to be valid. Statement: Despite improved internet speeds, cybersecurity threats continue to increase globally. Assumptions: I. Faster internet increases digital exposure. II. Cyber threats are unaffected by internet speed. II

Accepted Answer

Only I and III. The statement implies that improved internet speed may increase digital exposure, supporting assumption I. It also suggests that cybersecurity defenses are not sufficient to prevent the rise in threats, supporting assumption III. Assumption II is not necessary and is too absolute.

Question 15

Identify the odd one out:

Accepted Answer

D6: G9: K13. In options A, B, and C, both letters and numbers increase by a fixed pattern of +3 each step. In option D, the letters go D, G, K, which is not a constant +3 progression because G to K is +4.

Question 16

Identify the group that does NOT follow the same pattern:

Accepted Answer

E5: H9: K13. In options A, B, and C, the letters and numbers both increase by 3 at each step. In option D, the numbers go 5, 9, 13, which is not a +3 pattern.

Question 17

If FLOWER is coded as GMPXFS, then GARDEN is coded as:

Accepted Answer

HBSEFO. From FLOWER to GMPXFS, each letter is shifted forward alternately by +1 and +2. Applying the same pattern to GARDEN gives HBSEFO.

Question 18

A man says, “She is the daughter of my father’s only son.” How is the woman related to the man?

Accepted Answer

Daughter. "My father’s only son" refers to the man himself (assuming he is the only son). So the statement becomes: "She is the daughter of me," which means the woman is his daughter.

Question 19

Find the group of letters that best completes the analogy. Use alphabetical positions and reverse-position logic where necessary. BEKQ : YVPJ :: CFGL : ?

Accepted Answer

XUTO. The analogy follows a letter-shift pattern applied to each position. Applying the same positional transformation used from BEKQ to YVPJ gives CFGL as XUTO.

Question 20

Choose the odd one out: (17, P, #), (13, J, !), (19, R, %), (23, V, @)

Accepted Answer

(13, J, !). In three options, the letter corresponds to the number's position in the alphabet: 17→Q, 19→S, 23→W, but the given letters are shifted in a consistent pattern except one group breaks the intended relation. The set (13, J, !) is the odd one out based on the pattern used in the question.

Question 21

A's father's wife's only daughter is B. How is A related to B? (Assume A is a male member.)

Accepted Answer

Brother. A's father's wife is A's mother. The mother's only daughter is B, so B must be A's sister. Since A is male, he is B's brother.

Question 22

Choose the correct option to complete the series. Growth : Stagnation :: Success : ?

Accepted Answer

Failure. The relationship is antonymic: growth is opposed to stagnation. Similarly, success is opposed to failure, so 'Failure' is the correct answer.

Question 23

Select the letter cluster from among the given options that can replace the question mark (?) in the following series: PRT, OQS, NPR, ?

Accepted Answer

MOQ. In the series, the first letters go P, O, N, ... which decrease by 1 each time. The second letters go R, Q, P, ... and the third letters go T, S, R, ... so the next cluster is M, O, Q.

Question 24

Read the following statement carefully and identify the conclusion that follows. Statement: Smoking is prohibited in public places as per the new law. Conclusions: I. People can smoke in private spaces. II. Smoking harms public health.

Accepted Answer

Only Conclusion II follows. The statement only says smoking is prohibited in public places. It does not directly state anything about private spaces, so Conclusion I does not follow. Conclusion II is a generally accepted inference from the law’s context and is taken as following in such questions.

Question 25

If a × b = 2, where a × b = a^2 - b, what is the value of a and b?

Accepted Answer

2, 2. We need values of a and b such that a^2 - b = 2. Testing the options, only a = 2 and b = 2 gives 2^2 - 2 = 2. Hence that pair is correct.

Question 26

P + Q means P is the husband of Q, P - Q means P is the sister of Q, and P × Q means P is the mother of Q. Then what does A × B + C mean?

Accepted Answer

A is mother-in-law of C. A × B means A is the mother of B. B + C means B is the husband of C. Therefore, A is the mother of C's husband, which makes A the mother-in-law of C.

Question 27

Identify the odd number: 1, 8, 27, 64, 121, 216

Accepted Answer

121. The numbers are 1 = 1^3, 8 = 2^3, 27 = 3^3, 64 = 4^3, and 216 = 6^3. But 121 is not a cube; it is 11^2. So 121 is the odd one out.

Question 28

Each of the letters in the word HARMONIOUS is arranged in alphabetical order. How many letters are there in the English alphabetical series between the letter that is first from the left and the one that is fourth from the right in the new letter cluster formed?

Accepted Answer

13. The letters of HARMONIOUS in alphabetical order are A, H, I, M, N, O, O, R, S, U. The first from the left is A and the fourth from the right is O. The number of letters between A and O in the English alphabet is 13.

Question 29

Complete the series: 24, 120, 720, 5040, 40320, ?

Accepted Answer

362880. The terms are 4!, 5!, 6!, 7!, and 8!. Therefore, the next term is 9! = 362880. So the correct answer is 362880.

Question 30

Select the letter cluster from among the given options that can replace the question mark (?) in the following series: XJL, YMK, ZPJ, ?

Accepted Answer

ASI. The first letters go X, Y, Z, A, which is a forward cycle. The second letters go J, M, P, S, increasing by 3. The third letters go L, K, J, I, decreasing by 1. So the next cluster is ASI.

Question 31

Which of the following addresses are identical? 1. Vill. Rampur, PO Rampur, Dist. Aligarh - 202001 2. Vill Rampur, PO Rampur, Dist Aligarh - 202010 3. Vill. Rampur, PO Rampur, Dist. Aligarh - 202001

Accepted Answer

1 and 3 only. Addresses 1 and 3 are identical in wording and PIN code. Address 2 differs because its PIN code is 202010 instead of 202001, so it is not identical.

Question 32

“Science advances rapidly with innovation.” If the 2nd letter of every 2nd word is written in order, what word is formed?

Accepted Answer

di. The 2nd and 4th words are "advances" and "with". Their 2nd letters are "d" and "i", which form "di".

Question 33

Rani said, “The man in the photo is my mother’s brother.” How is the man related to Rani?

Accepted Answer

Uncle. Rani’s mother’s brother is her maternal uncle. Therefore, the man in the photo is Rani’s uncle.

Question 34

What will come in place of the question mark (?) in the series: 1, 2, 6, 21, 88, ?

Accepted Answer

445. The pattern is: $1	imes 1 + 1 = 2$, $2	imes 2 + 2 = 6$, $6	imes 3 + 3 = 21$, $21	imes 4 + 4 = 88$. Continuing the same pattern gives $88	imes 5 + 5 = 445$.

Question 35

Identify the assumptions that must hold true. Statement: Online education has expanded access to learning worldwide. Assumptions: I. Internet access is widely available. II. Learners are willing to adapt to digital platforms.

Accepted Answer

Both I and II. For online education to expand access worldwide, people must be able to connect to the internet and use digital platforms. Hence both assumptions are necessary for the statement.

Question 36

Statements: 1. No cats are dogs. 2. Some dogs are animals. Conclusions: I. Some animals are not cats. II. No dog is a cat.

Accepted Answer

Both follow. From statement 2, some dogs are animals. Statement 1 says no cats are dogs, so those dogs cannot be cats. Therefore, some animals are not cats, and also no dog is a cat follows directly from the first statement.

Question 37

If 6 * 4 = 40 and 8 * 3 = 33, then 5 * 6 = ?

Accepted Answer

66. For 6 * 4, the product is 24 and the result is 40, which is +16. For 8 * 3, the product is 24 and the result is 33, which is +9. The adjustment follows the square of the first number minus the second? A simpler consistent pattern here is not direct arithmetic, but among the options the intended coded result is 66.

Question 38

In a certain code, SCHOOL is written as XHMTTQ. How is TEACHER written?

Accepted Answer

YJFHMJW. The coding pattern shifts each letter of SCHOOL to a corresponding new letter. Applying the same letter-wise transformation to TEACHER gives the coded word. Among the options, YJFHMJW matches the intended pattern.

Question 39

Choose the address that is exactly the same as the one given below: A - 27, Green Valley, Sector - 5, Noida, Uttar Pradesh - 201301

Accepted Answer

A - 27, Green Valley, Sector - 5, Noida, Uttar Pradesh - 201301. This is a visual matching question. The correct option must match the given address exactly, including commas, hyphens, spaces, and the postal code. Option D is identical to the given address.

Question 40

Which of the following will fill the blanks? mn, op, __, st, uv

Accepted Answer

qr. The pairs are in alphabetical order with consecutive letters: mn, op, __, st, uv. The missing pair between op and st is qr. This maintains the pattern of advancing by two letters each time.

Question 41

Select the letter cluster that can replace the question mark: CDGH, FGJK, IJMN, ?

Accepted Answer

LMPQ. The first letters go C, F, I, L, increasing by 3. The second letters go D, G, J, M, also increasing by 3; similarly G, J, M, P and H, K, N, Q. So the next cluster is LMPQ.

Question 42

What will come at the place of the question mark? 2, 5, 11, 23, ?

Accepted Answer

47. The differences are 3, 6, and 12, which double each time. The next difference should be 24, so 23 + 24 = 47.

Question 43

Find the missing term in the series: 11, 22, 33, 44, ?

Accepted Answer

55. This is an arithmetic series with common difference 11. Adding 11 to 44 gives 55.

Question 44

Find the odd one out.

Accepted Answer

A1D4. In B2E6, C3F9, and D4G15, the numbers follow 2, 6; 3, 9; and 4, 15, which are based on a pattern of increasing values. A1D4 does not fit the same numerical progression as the others, so it is the odd one out.

Question 45

If 7 × 3 = 24 and 9 × 4 = 40, then 11 × 5 = ?

Accepted Answer

60. Here, 7 × 3 = 21 and the result is 24, which is 3 more. Also, 9 × 4 = 36 and the result is 40, which is 4 more. So the pattern is product + second number, giving 11 × 5 = 55 + 5 = 60.

Question 46

If “COLD” is coded as 3@15@12@4, how is “WARM” coded?

Accepted Answer

23@1@18@13. The code replaces each letter with its alphabetical position. COLD becomes 3@15@12@4, so WARM becomes 23@1@18@13. The same pattern is applied letter by letter.

Question 47

Sentence: “Knowledge grows with experience.” If each letter is mirrored using alphabetical symmetry (A ↔ Z, B ↔ Y, …), what is the 2nd letter of the 3rd word after coding?

Accepted Answer

r. The 3rd word is “with”. Under alphabetical symmetry, w ↔ d, i ↔ r, t ↔ g, and h ↔ s. Therefore, the 2nd letter after coding is r.

Question 48

In the following question, a pair of letters is related to a number by a certain logic. Identify the same relation for the next pair. AB → 2, CD → ?

Accepted Answer

6. AB corresponds to 1 + 2 = 3, but the given answer choices indicate the intended relation is likely the sum of positions minus 1, or a simple positional pattern leading to 2 for AB. For CD, C = 3 and D = 4, so the corresponding value is 6 as per the intended pattern in the options.

Question 49

Select the option that will correctly fill all the blanks in the series: m _ n m _ n _ _ n m _ _

Accepted Answer

a a m a a n. The series follows a pattern where the missing letters complete a repeating arrangement consistent with the visible letters. Among the options, only "a a m a a n" fits all positions correctly.

Question 50

Statement: Excessive use of plastic bags harms the environment. Assumptions: I. Plastic bags are non-biodegradable. II. People are aware of environmental damage caused by plastic. Choose the correct option.

Accepted Answer

Only I is implicit. The statement assumes that plastic bags cause environmental harm, which is consistent with them being non-biodegradable. However, it does not assume that people are already aware of this damage. Hence only I is implicit.
