Q1. Statements: Some Cats are Dogs. No Dog is a Lion. Conclusions: I. Some Cats are not Lions. II. No Cat is a Lion.
  1. Only conclusion I follows
  2. Only conclusion II follows
  3. Either conclusion I or II follows
  4. Both conclusions I and II follow

Answer: (A) Only conclusion I follows

The portion of Cats that are Dogs can never be Lions, so 'Some Cats are not Lions' definitely follows (Conclusion I). However, we cannot state that 'No Cat is a Lion' for all Cats (Conclusion II does not follow).

Q2. Statements: M ≥ N > O; P ≤ O = Q Conclusions: I. M > Q II. N > P
  1. Only conclusion I follows
  2. Only conclusion II follows
  3. Both conclusions I and II follow
  4. Neither conclusion I nor II follows

Answer: (C) Both conclusions I and II follow

Combining: M ≥ N > O = Q ≥ P. From M ≥ N > O = Q, we get M > Q (Conclusion I follows). From N > O ≥ P, we get N > P (Conclusion II follows).

Q3. In a certain code language, 'ORANGE' is written as 'PSBOHF'. How is 'GRAPES' written in that language?
  1. HSBQFT
  2. HSBQFT
  3. HSBRET
  4. HSBQF U

Answer: (A) HSBQFT

Each letter is shifted forward by +1: G+1=H, R+1=S, A+1=B, P+1=Q, E+1=F, S+1=T -> HSBQFT.

Q4. Statements: Only a few Books are Pens. No Pen is a Ruler. Conclusions: I. All Books can never be Pens. II. Some Books are Rulers.
  1. Only conclusion I follows
  2. Only conclusion II follows
  3. Both conclusions I and II follow
  4. Neither conclusion I nor II follows

Answer: (A) Only conclusion I follows

'Only a few Books are Pens' means Some Books are Pens and Some Books are NOT Pens, so All Books can never be Pens (Conclusion I follows). There is no definite relation between Books and Rulers (Conclusion II does not follow).

Q5. A person walks 9 km North, turns East and walks 12 km. What is the shortest distance between his starting point and ending point?
  1. 13 km
  2. 15 km
  3. 17 km
  4. 21 km

Answer: (B) 15 km

Using Pythagoras theorem: Distance = $\sqrt{9^2 + 12^2} = \sqrt{81 + 144} = \sqrt{225} = 15\text{ km}$.

Q6. In a row of 32 students facing North, R is 11th from the left end and S is 13th from the right end. How many students sit between R and S?
  1. 6
  2. 7
  3. 8
  4. 9

Answer: (C) 8

Sum of positions from ends = $11 + 13 = 24$. Since $24 < 32$, there is no overlap. Students between = $32 - 24 = 8$.

Q7. Pointing to a woman, Rahul said, 'She is the sister of my mother's only son.' How is the woman related to Rahul?
  1. Mother
  2. Sister
  3. Aunt
  4. Daughter

Answer: (B) Sister

'My mother's only son' refers to Rahul himself. The woman is the sister of Rahul, so she is Rahul's sister.

Q8. How many such pairs of letters are there in the word 'DESIGN' each of which has as many letters between them as in the English alphabet (in both directions)?
  1. None
  2. One
  3. Two
  4. Three

Answer: (C) Two

Letter positions: D(4), E(5), S(19), I(9), G(7), N(14). 1. (D, E) -> Consecutive letters (D=4, E=5). 2. Backward: G(7) and I(9) -> G, H, I (1 letter between). Total pairs = 2.

Q9. What should come in place of the question mark (?) in the following equation? $320 \div 8 + 14 \times 5 - 20 = ?$
  1. 80
  2. 85
  3. 90
  4. 95

Answer: (C) 90

Using BODMAS: $320 \div 8 = 40$ $14 \times 5 = 70$ $40 + 70 - 20 = 90$.

Q10. Find the missing term in the series: 7, 15, 31, 63, 127, ?
  1. 245
  2. 251
  3. 255
  4. 259

Answer: (C) 255

Pattern: $\times 2 + 1$. $7 \times 2 + 1 = 15$ $15 \times 2 + 1 = 31$ $31 \times 2 + 1 = 63$ $63 \times 2 + 1 = 127$ $? = 127 \times 2 + 1 = 255$.

Q11. A shopkeeper marks an item 50% above the cost price and gives a discount of 20%. What is his profit percentage?
  1. 15%
  2. 20%
  3. 25%
  4. 30%

Answer: (B) 20%

Profit % = $50 - 20 - \frac{50 \times 20}{100} = 30 - 10 = 20\%$.

Q12. The ratio of efficiency of A and B is 4 : 3. If they complete a piece of work together in 12 days, how many days will B take alone to complete it?
  1. 21 days
  2. 24 days
  3. 28 days
  4. 32 days

Answer: (C) 28 days

Combined efficiency per day = $4 + 3 = 7\text{ units}$. Total work = $7 \times 12 = 84\text{ units}$. Time taken by B alone = $\frac{84}{3} = 28\text{ days}$.

Q13. The simple interest on a sum of money for 3 years at 10% per annum is ₹1,500. Find the principal sum:
  1. ₹4,500
  2. ₹5,000
  3. ₹5,500
  4. ₹6,000

Answer: (B) ₹5,000

$SI = \frac{P \times R \times T}{100} \Rightarrow 1500 = \frac{P \times 10 \times 3}{100} \Rightarrow 30P = 150000 \Rightarrow P = ₹5,000$.

Q14. A train 200 meters long is running at a speed of 54 km/h. How much time will it take to cross a standing pole?
  1. 12 seconds
  2. 13.33 seconds
  3. 15 seconds
  4. 16.66 seconds

Answer: (B) 13.33 seconds

Speed = $54 \times \frac{5}{18} = 15\text{ m/s}$. Time = $\frac{\text{Distance}}{\text{Speed}} = \frac{200}{15} = 13.33\text{ seconds}$.

Q15. The average of 6 numbers is 25. If one number is excluded, the average becomes 22. Find the excluded number:
  1. 36
  2. 38
  3. 40
  4. 42

Answer: (C) 40

Sum of 6 numbers = $6 \times 25 = 150$. Sum of remaining 5 numbers = $5 \times 22 = 110$. Excluded number = $150 - 110 = 40$.

Q16. Solve the quadratic equations: $x^2 - 7x + 12 = 0$ $y^2 - 11y + 30 = 0$
  1. x > y
  2. x < y
  3. x ≤ y
  4. x ≥ y

Answer: (C) x ≤ y

For $x$: $(x-3)(x-4) = 0 \Rightarrow x = 3, 4$. For $y$: $(y-5)(y-6) = 0 \Rightarrow y = 5, 6$. Since both values of $x$ (3, 4) are strictly smaller than both values of $y$ (5, 6), $x < y$ (which implies $x \le y$).

Q17. The present ages of X and Y are in the ratio 4 : 5. Six years ago, the sum of their ages was 42 years. Find the present age of Y:
  1. 24 years
  2. 28 years
  3. 30 years
  4. 35 years

Answer: (C) 30 years

Present sum of ages = $42 + 6 + 6 = 54\text{ years}$. Ratio = $4 : 5$. Present age of Y = $\frac{5}{9} \times 54 = 30\text{ years}$.

Q18. Find the grammatical error in the given sentence: Hardly had I reached (A) / the station than the train (B) / departed from the platform. (C) / No error (D)
  1. Hardly had I reached
  2. the station than the train
  3. departed from the platform
  4. No error

Answer: (B) the station than the train

'Hardly' takes 'when' as its conjunction pair, not 'than'. ('Than' is used with 'No sooner').

Q19. Select the synonym of the underlined word: Her **candid** opinion helped us make an informed decision.
  1. Frank
  2. Secret
  3. Biased

  1. One of the students has forgotten
  2. One of the student has forgotten

  1. P Q R S
  2. Q P R S
  3. R S P Q
  4. P R Q S

Answer: (A) P Q R S

Logical sequence: 'renewable energy sources (P) / are essential for reducing (Q) / reliance on fossil fuels (R) / and curbing carbon emissions (S).' -> PQRS.
