পূর্বপদ বা পরপদ কোনটির অর্থ না বুঝিয়ে অন্য কিছু বোঝালে কোন সমাস হয়?
- a)দ্বিগু
- b)তৎপুরুষ
- c)বহুব্রীহি (correct answer)
- d)কর্মধারয়
Answer and explanation
Correct answer: (c) বহুব্রীহি
সঠিক উত্তর: (c) বহুব্রীহি
NCTB-র সংজ্ঞা: যে সমাসে পূর্বপদ বা পরপদ কোনোটির অর্থ না বুঝিয়ে অন্য কিছু বোঝায়, তাকে বহুব্রীহি সমাস বলে; যেমন বউ ভাত পরিবেশন করে যে অনুষ্ঠানে = বউভাত।
অন্য বিকল্প: (a) দ্বিগু — পূর্বপদ সংখ্যাবাচক কর্মধারয় (তিন ফলের সমাহার = ত্রিফলা); (b) তৎপুরুষ — বিভক্তি বা অনুসর্গ লোপ পায়, পরপদের অর্থ প্রধান (ধানের খেত = ধানখেত); (d) কর্মধারয় — পরপদের অর্থ প্রাধান্য পায় (গোলাপ নামের ফুল = গোলাপফুল)।
আরও জেনে রাখুন:
- সমাস মূলত চার প্রকার: দ্বন্দ্ব, কর্মধারয়, তৎপুরুষ ও বহুব্রীহি।
- দ্বন্দ্ব সমাসে দুই পদের অর্থের সমান প্রাধান্য থাকে (সোনা ও রুপা = সোনা-রুপা)।
- পূর্বপদের বিভক্তি অক্ষুণ্ন থাকলে অলুক বহুব্রীহি: গায়ে এসে পড়ে যে = গায়েপড়া।
- হাতে হাতে যে যুদ্ধ = হাতাহাতি (ব্যতিহার বহুব্রীহি)।
“সে তিন দিন পথ চলল।” — ‘তিন দিন’ কোন কারকে কোন বিভক্তি?
- a)কর্মে শূন্য
- b)করণে তৃতীয়া
- c)অপাদানে শূন্য
- d)অধিকরণে শূন্য
Which country first recognised Bangladesh?
- a)Bhutan

log₂4 + log₂8 − log₄16 = ?
- a)1
- b)2
- c)3 (correct answer)
- d)4
Answer and explanation
Correct answer: (c) 3
- log₂4 = 2, because 2² = 4.
- log₂8 = 3, because 2³ = 8.
- log₄16 = 2, because 4² = 16.
- 2 + 3 − 2 = 3.
Check: log₂4 + log₂8 = log₂32 = 5; by change of base, log₄16 = log₂16 ÷ log₂4 = 4 ÷ 2 = 2; 5 − 2 = 3.
Other options: (a) 1 and (b) 2 — do not equal 2 + 3 − 2; (d) 4 — the result if log₄16 is wrongly taken as 1 (2 + 3 − 1).
Also know:
- log_b x = y means b^y = x (logarithmic and exponential forms of the same relation).
- log_b(xy) = log_b x + log_b y, log_b(x/y) = log_b x − log_b y, and log_b xⁿ = n·log_b x.
- Change of base: log_b x = log_n x ÷ log_n b; also log_b a = 1 ÷ log_a b.

If A = 2i − 3j + 4k and B = i + 2j − k, then A·B = ?
- a)−8 (correct answer)
- b)0
- c)1
- d)5
Answer and explanation
Correct answer: (a) −8
The dot product multiplies matching components and adds them:
- i: 2 × 1 = 2.
- j: (−3) × 2 = −6.
- k: 4 × (−1) = −4.
- A·B = 2 − 6 − 4 = −8.
Check: B·A = 1·2 + 2·(−3) + (−1)·4 = −8 (the dot product is commutative).
Other options: (b) 0 — the result if the minus sign on k in B is dropped (2 − 6 + 4); a zero dot product would mean the vectors are perpendicular; (c) 1 and (d) 5 — do not equal 2 − 6 − 4.
Also know:
- A·B = |A||B|cos θ; here |A| = √29 and |B| = √6, and since A·B < 0 the angle between them is obtuse.
- The dot product of two nonzero vectors is zero exactly when they are perpendicular.
- The dot product is a scalar, not a vector.

Arc length subtending 60° in a circle of radius 30 cm —
- a)π/6
- b)6π
- c)10π (correct answer)
- d)20π
Answer and explanation
Correct answer: (c) 10π
Arc length on a circle is s = rθ, with θ in radians.
- 60° = 60 × π/180 = π/3 radians.
- s = 30 × π/3 = 10π cm (≈ 31.4 cm).
Check: the full circumference is 2π × 30 = 60π; 60° is 1/6 of 360°, and 60π ÷ 6 = 10π.
Other options: (a) π/6 — this is 30° in radians and leaves out the radius; (b) 6π — 30θ = 6π means θ = π/5 = 36°, not 60°; (d) 20π — 30θ = 20π means θ = 2π/3 = 120°.
Also know:
- A full angle is 2π radians = 360°, so 1 radian ≈ 57.3°.
- A right angle is π/2 radians.
- One radian is the angle whose arc length equals the radius.

Probability that the sum is 7 when two dice are thrown —
- a)1/4
- b)1/5
- c)2/5
- d)1/6 (correct answer)
Answer and explanation
Correct answer: (d) 1/6
- Two dice give 6 × 6 = 36 equally likely outcomes.
- Sum 7: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) — 6 outcomes.
- P = 6/36 = 1/6.
Check: whatever the first die shows, exactly one face of the second die makes 7, so P = 1/6.
Other options: (a) 1/4 — would need 9 of 36 outcomes, but no total has more than 6; (b) 1/5 and (c) 2/5 — not possible, since every probability here is a whole number of 36ths (1/5 = 7.2/36).
Also know:
- 7 is the most likely total with two dice; 2 and 12 are the least likely, 1/36 each.
- For two dice, P(total p) = (6 − |p − 7|)/36 for p = 2 to 12.
- So P(6) = P(8) = 5/36.
