Q. 01-05: Select the word(s) that appropriately fill(s) in the gap(s) in each sentence.
1. Although the leader's life was both _______ and painful, it was not without ______ for he had accomplished many of his goals.

(a) magnificent, success (b) thrilling, ambition (c) happy, frustration (d) arduous, satisfaction (e) good, damage

Answer: (d) arduous, satisfaction

Explanation: 'Painful' already conveys suffering, so the first blank needs a matching word describing hardship — 'arduous' (difficult, strenuous). The clause 'not without ___' means 'did have some ___ nonetheless', which logically pairs with 'satisfaction' since he had accomplished many of his goals despite the hardship. The other pairs (magnificent/success, thrilling/ambition, happy/frustration, good/damage) do not fit this cause-and-effect logic. Complete sentence: 'Although the leader's life was both arduous and painful, it was not without satisfaction for he had accomplished many of his goals.'

2. Since the lady's face was free of _____ there was no way to _____ if she appreciated what had happened.

(a) scars, understand (b) emotion, diagnose (c) Expression, ascertain (d) make-up, realize (e) None of these

Answer: (c) Expression, ascertain

Explanation: A face 'free of expression' means an expressionless/blank face that reveals no feeling. Since her face revealed nothing, there was no way to 'ascertain' (find out for certain) whether she appreciated what had happened. 'Ascertain' precisely matches the sense of 'no way to know for sure', unlike 'understand', 'diagnose' or 'realize'. Complete sentence: 'Since the lady's face was free of expression, there was no way to ascertain if she appreciated what had happened.'

3. Sakib's _______ background has made him so docile.

(a) humble (b) rich (c) advanced (d) lucrative (e) sound

Answer: (a) humble

Explanation: 'Docile' means submissive, meek, or easily managed. A 'humble' (modest, unassuming) upbringing logically explains why someone would grow up to be docile. 'Rich', 'advanced', 'lucrative' (profitable), and 'sound' (stable) backgrounds have no such causal link with docility. Complete sentence: 'Sakib's humble background has made him so docile.'

4. ______ my insistence to the contrary, Samrin ______ pursued her preferred line of action.

(a) Despite, doggedly (b) According to, obligingly (c) Following, otherwise (d) In spite, nonetheless (e) None of these

Answer: (a) Despite, doggedly

Explanation: 'Despite' is a preposition that can be followed directly by a noun phrase ('my insistence'), whereas 'in spite' is grammatically incomplete without 'of' ('in spite of'), which rules out option (d). 'Despite my insistence to the contrary' means 'even though I insisted otherwise'; the second blank should show how Samrin still pursued her own course of action, and 'doggedly' (persistently, stubbornly) fits this perfectly. Complete sentence: 'Despite my insistence to the contrary, Samrin doggedly pursued her preferred line of action.'

5. Although it _____ often buy, sell and operate subsidiaries outside of their home locations, it is important to try to understand how industries _____ particular localities.

(a) is also true that firms, function within (b) is true that firms, function at (c) is true that firms, functions within (d) is true that firms, function within (e) None of these

Answer: (b) is true that firms, function at

Explanation: The subject 'firms' is plural, so the verb must be 'function' (not 'functions'), which eliminates option (c). A business is described as being active or operating 'at' a particular location, not 'within' a locality — 'function within' would wrongly suggest being physically enclosed inside the locality's boundaries rather than being situated and active there. Plain 'is true' (without 'also') also fits better since no earlier point is being added to. Complete sentence: 'Although it is true that firms often buy, sell and operate subsidiaries outside of their home locations, it is important to try to understand how industries function at particular localities.'

Q. 06-10: Choose the word which best expresses the OPPOSITE meaning of the given word.
6. EMBRACE

(a) Disobey (b) Reject (c) Obscure (d) Contradict (e) Insult

Answer: (b) Reject

Explanation: 'Embrace' means to accept or welcome willingly (an idea, offer, or belief). Its direct opposite is 'Reject', meaning to refuse to accept. 'Disobey' (to defy authority), 'Obscure' (unclear), 'Contradict' (to oppose in words) and 'Insult' (to offend) do not carry the opposite sense of acceptance versus refusal.

7. PROVOKE

(a) Soothe (b) Anger (c) Encourage (d) Express (e) Ravenous

Answer: (a) Soothe

Explanation: 'Provoke' means to stir up anger, irritation, or a strong reaction in someone. Its opposite is 'Soothe', meaning to calm or comfort. 'Anger' is closer in meaning to provoke (not opposite), while 'Encourage', 'Express' and 'Ravenous' (extremely hungry) are unrelated in meaning.

8. ENORMOUS

(a) Average (b) Weak (c) Tiny (d) Soft (e) Spacious

Answer: (c) Tiny

Explanation: 'Enormous' means extremely large in size. Its direct opposite is 'Tiny', meaning very small. 'Average' describes a middling size (not an opposite extreme), while 'Weak', 'Soft' and 'Spacious' describe unrelated qualities rather than the opposite of size.

9. RELINQUISH

(a) Possess (b) Deny (c) Renounce (d) Abdicate (e) Experimental

Answer: (a) Possess

Explanation: 'Relinquish' means to give up, surrender, or let go of something, such as a right, position, or possession. Its opposite is 'Possess', meaning to hold or own something. 'Renounce' and 'Abdicate' are actually synonyms of 'relinquish' (they too mean to formally give something up), not opposites, and 'Deny' and 'Experimental' are unrelated in meaning.

10. GLOOMY

(a) Adjudicate (b) Tragic (c) Disguising (d) Dispute (e) Bright

Answer: (e) Bright

Explanation: 'Gloomy' means dark, dismal, or depressing in mood or appearance. Its opposite is 'Bright', meaning cheerful or full of light. 'Adjudicate' (to judge a dispute), 'Tragic', and 'Dispute' are unrelated in meaning, and 'Disguising' has no connection to mood.

Q. 11-15: In the following questions, choose the answer that best expresses the meaning of the underlined part of the sentence.
11. Jeny visits the doctor off and on.

(a) Occasionally (b) Regularly (c) Everyday (d) Never at all (e) Once in a week

Answer: (a) Occasionally

Explanation: The idiom 'off and on' (also 'on and off') means happening irregularly, now and then — i.e., 'occasionally'. It does not mean happening on a regular, daily, weekly, or non-existent basis.

12. I have a bone to pick with mita in this matter.

(a) Will join hands (b) Am angry (c) Am in agreement (d) Am indebted (e) Will confide

Answer: (b) Am angry

Explanation: 'To have a bone to pick with someone' is an idiom meaning to have a grievance or disagreement with that person that one wants to discuss or complain about — i.e., to be displeased or angry with them over a specific matter. It does not mean joining hands, agreeing, owing a debt, or confiding.

13. There was no opposition to the new policy by the rank and file of the government.

(a) The ordinary members (b) The cabinet ministers (c) The parliament (d) The majority (e) The opposition

Answer: (a) The ordinary members

Explanation: 'Rank and file' (originally a military term for regular soldiers as opposed to officers) refers to the ordinary members of an organisation, as distinguished from its leaders. Hence 'the rank and file of the government' means its ordinary members/employees, not its cabinet ministers, parliament, majority, or opposition specifically.

14. The President of the club believes in the policy of making hay while the sun shines.

(a) Seeking advice from one and all (b) Waiting for the suitable time to come (c) Giving bribes to get his work done (d) Making the best use of a favorable situation (e) Helping those who help him

Answer: (d) Making the best use of a favorable situation

Explanation: The idiom 'make hay while the sun shines' — derived from the practice of drying cut grass only in good, sunny weather — means to take full advantage of favourable conditions or opportunities while they last. It does not mean seeking advice, merely waiting, bribing, or helping only those who help oneself.

15. The new king did not take after his father.

(a) precede (b) follow (c) run after (d) contradict (e) resemble

Answer: (e) resemble

Explanation: 'Take after' is a phrasal verb meaning to resemble a parent or relative in appearance, character, or habits. It does not mean to precede, to follow in succession, to chase ('run after'), or to contradict.

Q. 16-20: The underlined part of the following sentences may contain problems in grammar, sentence construction, word choice, and punctuation. Identify the option that best replaces the underlined portion.
16. Princess Diana, who died at the age of 45, was remembered as to be a great personality of all times.

(a) Who died at the age of 45, was remembered as be a great personality. (b) Died at the age of 45, have been remembered as a great personality. (c) Who died at the age of 45, will be remembered being a great personality. (d) Who died at the age of 45, will be remembered as a great personality. (e) No correction required.

Answer: (d) Who died at the age of 45, will be remembered as a great personality.

Explanation: The original sentence contains the faulty construction 'was remembered as to be a great personality' — the phrase 'remembered as' must be followed directly by a noun phrase ('remembered as a great personality'), not by 'to be'. Option (a) still keeps the flawed form 'remembered as be'; option (b) drops the relative pronoun 'who' and wrongly pairs the plural auxiliary 'have' with the singular subject 'Diana' (it should be 'has'); option (c) uses the incorrect form 'remembered being'. Option (d) correctly retains the relative clause 'who died at the age of 45' and uses the proper construction 'will be remembered as a great personality', so it is the best correction.

17. But for your help, I would not have been able to pass the exam.

(a) that you helped me (b) in case you helped me (c) without you helping (d) If you had helped me (e) No correction required

Answer: (e) No correction required

Explanation: 'But for' is a fixed idiomatic expression meaning 'without' or 'if it had not been for', commonly used to open a third-conditional sentence — and it is correctly followed here by the conditional perfect 'would not have been able to pass the exam'. The sentence is already grammatically correct, so no correction is required.

18. Although the country is self-sufficient in defence equipment, it is in want of peace and security.

(a) it was to have peace an security (b) is possesses peace and security (c) is taking in peace and security (d) it wants to be in peace and security (e) No correction required.

Answer: (e) No correction required.

Explanation: 'Self-sufficient in' and 'in want of' (meaning lacking or in need of) are both correctly and idiomatically used here. The sentence correctly contrasts the country's sufficiency in defence equipment with its lack of peace and security, so no correction is required.

19. Seeming to be the only party fighting for the rights of people, Mr. Alamgir, a political leader in Dhaka, joined the socialism party in 1999.

(a) As (b) Seeming to have (c) Because it seemed to be (d) Since it seemed (e) No correction required.

Answer: (c) Because it seemed to be

Explanation: The original sentence opens with the dangling participial phrase 'Seeming to be the only party...', which illogically appears to modify 'Mr. Alamgir' (a person) rather than 'the party' — a person cannot literally 'seem to be a party'. The correction must supply an explicit subject ('it', referring to the party) through a proper subordinate clause: 'Because it seemed to be the only party fighting for the rights of the people, Mr. Alamgir... joined the socialism party in 1999.' This correctly resolves the dangling modifier.

20. The warden did not approve with the student's behaviour.

(a) Approve with that of student's behaviour (b) approve about the student's behaviour (c) approve with that of the student behaviour (d) approve of the student's behaviour (e) No correction required.

Answer: (d) approve of the student's behaviour

Explanation: When 'approve' means to have a favourable opinion of something, it must take the preposition 'of' ('approve of'), not 'with'. Hence the correct form is: 'The warden did not approve of the student's behaviour.'

২১. By selling a book for Tk. 675, a seller loses 2/9 of his outlay, by selling it for Tk. 810, his gain or loss percentage is -

(a) 10% loss (b) 20% gain (c) 7% gain (d) No gain or loss (e) None

উত্তর: (e) None

ব্যাখ্যা: ৬৭৫ টাকায় বিক্রি করলে ক্রয়মূল্যের (outlay) ২/৯ অংশ ক্ষতি হয়, অর্থাৎ বিক্রয়মূল্য = ক্রয়মূল্য − (২/৯)×ক্রয়মূল্য = (৭/৯)×ক্রয়মূল্য। সুতরাং ক্রয়মূল্য = ৬৭৫ × (৯/৭) = ৬০৭৫/৭ ≈ ৮৬৭.৮৬ টাকা। এখন ৮১০ টাকায় বিক্রি করলে (ক্রয়মূল্যের চেয়ে কম হওয়ায়) তখনও ক্ষতিই হয় = ৮৬৭.৮৬ − ৮১০ ≈ ৫৭.৮৬ টাকা। ক্ষতির হার = (৫৭.৮৬/৮৬৭.৮৬)×১০০ ≈ ৬.৬৭% ক্ষতি। প্রদত্ত অপশনগুলোর (১০% ক্ষতি, ২০% লাভ, ৭% লাভ, লাভ-ক্ষতি শূন্য) কোনোটির সাথেই এই মান হুবহু মেলে না, তাই সঠিক উত্তর 'None'।

২২. The average of three numbers is P. If two numbers of them are R and S, what is the 3^rd number?

(a) P - R - S (b) 3R - P - R (c) - S + 3P + S (d) - R + 3P - S (e) None

উত্তর: (d) - R + 3P - S

ব্যাখ্যা: তিনটি সংখ্যার গড় P হলে তাদের সমষ্টি = 3P। দুটি সংখ্যা R ও S হলে তৃতীয় সংখ্যা = 3P − R − S, যা বীজগাণিতিক আকারে −R + 3P − S-এর সমান।

২৩. If 100 is divided into two parts in such a way that the sum of their reciprocals is 1/21, the difference between the two parts is -

(a) 30 (b) 40 (c) 45 (d) 50 (e) None

উত্তর: (b) 40

ব্যাখ্যা: ধরি সংখ্যা দুটি x ও y। x+y=100 এবং 1/x + 1/y = 1/21 ⟹ (x+y)/(xy) = 1/21 ⟹ 100/xy = 1/21 ⟹ xy = 2100। x ও y হলো t² − 100t + 2100 = 0 সমীকরণের মূল। মূল দুটি = [100 ± √(10000−8400)]/2 = [100±40]/2 = 70 এবং 30। পার্থক্য = 70−30 = 40।

২৪. Tanvir has 450 coins of 50 paisa and 500 coins of 1 Tk. If he gives 46% of 50 paisa coins and 54% of 1 Tk. coins to his brother, the amount of money remaining with Tanvir will be -

(a) 416.5 (b) 414.5 (c) 313.5 (d) 301.5 (e) None

উত্তর: (e) None

ব্যাখ্যা: ৪৬% ৫০ পয়সার মুদ্রা দিলে অবশিষ্ট থাকে ৫৪% × ৪৫০ = ২৪৩টি মুদ্রা, যার মূল্য = ২৪৩ × ০.৫ = ১২১.৫ টাকা। ৫৪% ১ টাকার মুদ্রা দিলে অবশিষ্ট থাকে ৪৬% × ৫০০ = ২৩০টি মুদ্রা, যার মূল্য = ২৩০ × ১ = ২৩০ টাকা। মোট অবশিষ্ট টাকা = ১২১.৫ + ২৩০ = ৩৫১.৫ টাকা, যা প্রদত্ত কোনো অপশনের (৪১৬.৫, ৪১৪.৫, ৩১৩.৫, ৩০১.৫) সাথেই মেলে না। তাই সঠিক উত্তর 'None'।

২৫. Of three consecutive even numbers, the sum of the 1st and 2nd is 166. The sum of the 2nd and 3rd is 170 and the sum of the 3rd and twice of 1st is 250. The second number is -

(a) 78 (b) 82 (c) 86 (d) 88 (e) None

উত্তর: (e) None

ব্যাখ্যা: পরপর তিনটি জোড় সংখ্যা a, a+2, a+4 ধরি। ১ম+২য় = a+(a+2) = 2a+2 = 166 ⟹ a = 82। তাহলে সংখ্যাগুলো হলো ৮২, ৮৪, ৮৬। যাচাই করলে দেখা যায় ২য়+৩য় = 84+86 = 170 এবং ৩য়+২×১ম = 86+164 = 250 — উভয় শর্তই মিলে যায়। সুতরাং দ্বিতীয় সংখ্যা = ৮৪, যা প্রদত্ত অপশনগুলোর (৭৮, ৮২, ৮৬, ৮৮) কোনোটির সাথেই মেলে না। তাই সঠিক উত্তর 'None'।

২৬. A bus travels a distance of 315 km at a uniform speed. If the speed of the bus were 90% of the original speed, it would have taken 2.5 hours more to cover the same distance. The original speed was-

(a) 14 Km/hour (b) 13 Km/hour (c) 12.6 Km/hour (d) 11.6 Km/hour (e) None

উত্তর: (a) 14 Km/hour

ব্যাখ্যা: মূল গতিবেগ v হলে সময় লাগে 315/v ঘণ্টা। গতিবেগ ৯০% অর্থাৎ 0.9v হলে সময় লাগবে 315/(0.9v) = 350/v ঘণ্টা। শর্তমতে, 350/v − 315/v = 2.5 ⟹ 35/v = 2.5 ⟹ v = 14 কিমি/ঘণ্টা।

২৭. A bike traveled twice as many kms from X to Y as it did from Y to Z. From X to Y, the bike averaged 16 Km/gallon and from Y to Z, the bike averaged 24 Km/gallon. What is the average Km/gallon that the bike achieved on its trip from X through Y to Z?

(a) 28.8 (b) 32 (c) 36.8 (d) 48 (e) None

উত্তর: (e) None

ব্যাখ্যা: ধরি Y থেকে Z দূরত্ব = d, তাহলে X থেকে Y দূরত্ব = 2d। X-Y ভ্রমণে জ্বালানি ব্যয় = 2d/16 = d/8 গ্যালন। Y-Z ভ্রমণে জ্বালানি ব্যয় = d/24 গ্যালন। মোট দূরত্ব = 3d এবং মোট জ্বালানি = d/8 + d/24 = 4d/24 = d/6 গ্যালন। গড় মাইলেজ = মোট দূরত্ব ÷ মোট জ্বালানি = 3d ÷ (d/6) = 18 কিমি/গ্যালন। এই মান প্রদত্ত অপশনগুলোর (28.8, 32, 36.8, 48) কোনোটির সাথেই মেলে না, তাই সঠিক উত্তর 'None' (প্রকৃত distance-weighted গড় হলো 18, সরল গাণিতিক গড় (16+24)/2=20 নয়)।

২৮. The output of a glass factory was increased by 12% to keep up with the rising demand. Later, this new output was increased by another 25%. By approximately what percentage would the output now have to be decreased in order to restore the original output?

(a) 28.6% (b) 24.7% (c) 32.8% (d) 40% (e) None

উত্তর: (a) 28.6%

ব্যাখ্যা: ধরি মূল উৎপাদন = ১০০ একক। ১২% বৃদ্ধিতে হয় = ১১২। এরপর আরও ২৫% বৃদ্ধিতে হয় = ১১২ × ১.২৫ = ১৪০। এখন ১৪০ থেকে মূল ১০০-তে ফিরতে হ্রাস করতে হবে = (১৪০−১০০)/১৪০ × ১০০% = ৪০/১৪০ × ১০০% ≈ ২৮.৬%।

২৯. A forester wants to plant 66 coconut trees, 88 date trees and 110 plum trees in equal sized rows (in terms of number of trees). Also he wants to make distinct rows of trees (i.e. only one type of trees in one row). What is the minimum number of rows required?

(a) 12 (b) 22 (c) 11 (d) 24 (e) None

উত্তর: (a) 12

ব্যাখ্যা: ৬৬, ৮৮ ও ১১০-এর গ.সা.গু (H.C.F.) = ২২। প্রতি সারিতে ২২টি করে গাছ রাখলে - নারিকেল গাছের সারি = 66/22 = 3টি, খেজুর গাছের সারি = 88/22 = 4টি এবং বরই গাছের সারি = 110/22 = 5টি। মোট সারি = 3+4+5 = 12টি, যা সর্বনিম্ন সংখ্যক সারি।

৩০. If we double a certain number and add 30 to it, we get the same value as four times that number. What is the value of thrice the number?

(a) 12 (b) 15 (c) 30 (d) 45 (e) None

উত্তর: (d) 45

ব্যাখ্যা: ধরি সংখ্যাটি x। শর্তমতে, 2x + 30 = 4x ⟹ 30 = 2x ⟹ x = 15। সংখ্যাটির তিনগুণ = 3 × 15 = 45।

৩১. Fahim's collection contains US, Bangladeshi and British stamps. If the ratio of US to Bangladeshi stamps is 5 : 2 and the ratio of Bangladeshi to British stamps is 5 : 1, what is the ratio of US to British stamps?

(a) 5 : 1 (b) 10 : 5 (c) 15 : 2 (d) 20 : 2 (e) 25 : 2

উত্তর: (e) 25 : 2

ব্যাখ্যা: US : Bangladeshi = 5:2 এবং Bangladeshi : British = 5:1। উভয় অনুপাতে Bangladeshi-র মান সমান করতে প্রথমটিকে ৫ দ্বারা ও দ্বিতীয়টিকে ২ দ্বারা গুণ করি: US:Bangladeshi = 25:10 এবং Bangladeshi:British = 10:2। সুতরাং US:Bangladeshi:British = 25:10:2, অর্থাৎ US:British = 25:2।

৩২. Six years ago, Anika was P times as old as Bulbul was. If Anika is now 17 years old, how old is Bulbul now in terms of P?

(a) (11/P) + 6 (b) (P/11) + 6 (c) 17 - (P/6) (d) 17/P (e) 11.5P

উত্তর: (a) (11/P) + 6

ব্যাখ্যা: বর্তমানে আনিকার বয়স ১৭, তাই ৬ বছর আগে তার বয়স ছিল ১৭−৬=১১। ৬ বছর আগে আনিকার বয়স = P × (তখনকার বুলবুলের বয়স), অর্থাৎ ১১ = P × (তখনকার বুলবুলের বয়স) ⟹ তখনকার বুলবুলের বয়স = 11/P। বর্তমানে বুলবুলের বয়স = (11/P) + 6।

৩৩. A certain animal in the zoo has consumed 39 pounds of food in six days. If it continues to eat at the same rate, in how many more days will its total consumption be 91 pounds?

(a) 12 (b) 11 (c) 10 (d) 9 (e) 8

উত্তর: (e) 8

ব্যাখ্যা: ৬ দিনে ৩৯ পাউন্ড খাবার খেলে প্রতিদিন খায় = 39/6 = 6.5 পাউন্ড। মোট ৯১ পাউন্ড খেতে বাকি থাকে = 91−39 = 52 পাউন্ড। তাই আরও লাগবে = 52/6.5 = 8 দিন।

৩৪. If n is even, which of the following cannot be odd?

(a) n + 3 (b) 3(n + 1) (c) 2(n + 3) + 3 (d) n² - 1 (e) 2(n + 3)

উত্তর: (e) 2(n + 3)

ব্যাখ্যা: n জোড় সংখ্যা হলে - (a) n+3 = জোড়+বিজোড় = সবসময় বিজোড়, (b) n+1 বিজোড় হওয়ায় 3(n+1) = 3×বিজোড় = সবসময় বিজোড়, (c) 2(n+3) সবসময় জোড়, তার সাথে 3 যোগ করলে সবসময় বিজোড় হয়, (d) n জোড় হলে n² জোড়, তাই n²−1 সবসময় বিজোড়। কিন্তু (e) 2(n+3)-এ 2 দ্বারা গুণ করা যেকোনো রাশিই সবসময় জোড় হবে, কখনোই বিজোড় হতে পারে না। তাই এটিই একমাত্র রাশি যা বিজোড় হতে পারে না।
