The average of 5 consecutive odd natural numbers is 47. Previous 5 consecutive odd natural numbers to these 5 odd natural numbers are also included. What will be the average of the newly added numbers?
5 लगातार विषम प्राकृत संख्याओं का औसत 47 है। इन 5 विषम प्राकृत संख्याओं से पिछली 5 लगातार विषम प्राकृत संख्याएं भी शामिल की जाती हैं। नई जोड़ी गई संख्याओं का औसत क्या होगा?
Answer: C) 3737
Average of 5 consecutive odd numbers = 47; so middle number = 47
The 5 numbers: 43, 45, 47, 49, 51
Previous 5 consecutive odd numbers: 33, 35, 37, 39, 41
Average of newly added = 37 (middle of the new group)
Answer: Option 3 = 375 क्रमागत विषम संख्याओं का औसत = 47; तो बीच की संख्या = 47
5 संख्याएँ: 43, 45, 47, 49, 51
पिछली 5 क्रमागत विषम संख्याएँ: 33, 35, 37, 39, 41
नई जोड़ी गई संख्याओं का औसत = 37 (नए समूह के मध्य की संख्या)
उत्तर: विकल्प 3 = 37 -

If sin A = 3/5 and cos B = 12/13, A and B ∈ (0, π/2), find sin(A + B).
यदि sin A = 3/5 और cos B = 12/13 है, जहाँ A और B ∈ (0, π /2) हैं, तो sin(A + B) ज्ञात कीजिए।
Answer: A) 56/6556/65
cos A = 4/5; sin B = 5/13 (both A and B in first quadrant).
sin(A + B) = sin A cos B + cos A sin B.
= (3/5)(12/13) + (4/5)(5/13) = 36/65 + 20/65 = 56/65.cos A = 4/5; sin B = 5/13 (A और B दोनों प्रथम चतुर्थांश में हैं)।
sin(A + B) = sin A cos B + cos A sin B।
= (3/5)(12/13) + (4/5)(5/13) = 36/65 + 20/65 = 56/65। -

A, B, and C enter into a partnership. A invests Rs. 80,000, B invests Rs. 60,000, and C invests Rs. 40,000. After 6 months, B increases his capital by 25%, while C decreases his capital by 10%. At the end of 1 year, the total profit is Rs. 1,20,000. What is C's share in the profit?
A, B और C एक साझेदारी में प्रवेश करते हैं। A, 80,000 रुपये का निवेश करता है, B, 60,000 रुपये का निवेश करता है, और C, 40,000 रुपये का निवेश करता है। 6 महीने के बाद, B अपनी पूंजी में 25% की वृद्धि करता है, जबकि C अपनी पूंजी में 10% की कमी करता है। 1 वर्ष के अंत में, कुल लाभ 1,20,000 रुपये है। लाभ में C का हिस्सा कितना है?
Answer: B) Rs. 24,582रु. 24,582
A's capital-months = 80,000 × 12 = 9,60,000
B's capital-months = 60,000 × 6 + (60,000 × 1.25) × 6 = 3,60,000 + 4,50,000 = 8,10,000
C's capital-months = 40,000 × 6 + (40,000 × 0.90) × 6 = 2,40,000 + 2,16,000 = 4,56,000
Total = 9,60,000 + 8,10,000 + 4,56,000 = 22,26,000
C's share = (4,56,000/22,26,000) × 1,20,000 = (76/371) × 1,20,000 ≈ Rs. 24,582A की पूंजी-महीने = 80,000 × 12 = 9,60,000
B की पूंजी-महीने = 60,000 × 6 + (60,000 × 1.25) × 6 = 3,60,000 + 4,50,000 = 8,10,000
C की पूंजी-महीने = 40,000 × 6 + (40,000 × 0.90) × 6 = 2,40,000 + 2,16,000 = 4,56,000
कुल = 9,60,000 + 8,10,000 + 4,56,000 = 22,26,000
C का हिस्सा = (4,56,000/22,26,000) × 1,20,000 = (76/371) × 1,20,000 ≈ रु. 24,582 -

In a certain code language, 'silver ring shines' is written as 'na tu ke', 'gold ring costs' is written as 'pa tu mi' and 'silver and gold' is written as 'na pa zo'. What is the code for 'ring'?
Answer: A) tu
Rule: a word common to two sentences takes the code common to those two codes.
Compare the sentences with 'ring'.
silver ring shines → na tu ke
gold ring costs → pa tu mi
Common word: ring; common code: tu
Confirm with the third sentence.
silver and gold → na pa zo
silver = na, gold = pa — so na and pa are taken, leaving tu for ring.
Answer: tu
zo is "and" — it appears only once, so it can never be a shared word. -

If □ = +, ○ = −, Δ = ×, ∇ = ÷, find the value of 8 Δ 4 □ 12 ∇ 6 ○ 2.
Answer: D) 32
Rule: replace each symbol by its sign, then apply BODMAS — ÷ and × before + and −.
Substitute the signs.
8 × 4 + 12 ÷ 6 − 2
Division and multiplication.
8 × 4 = 32
12 ÷ 6 = 2
Addition and subtraction.
32 + 2 − 2 = 32
Answer: 32
Working strictly left to right gives (32 + 12) ÷ 6 … — a wrong value; BODMAS comes first. -
Q6Reasoning · Decision MakingSSC Selection Post Ph-14 2026 · Matriculation - 22 Sep 2026 Shift 3
During office hours, a caller asks for the OTP sent to your phone, saying it is needed to update your bank salary account. What is the best decision?
Answer: C) Do not share the OTP and report the call as fraudulent
Rule: in decision-making items, choose the action that removes the risk completely and follows the official rule — not one that depends on guesswork.
The fact that decides it.
Banks never ask for an OTP over a call. An OTP is a one-time password that authorises a transaction; whoever holds it can move money.
So the right action is to refuse and report the call (to the bank or the cyber-crime helpline 1930).
Why the others fail.
• Caller knows your office details — such details are easy to collect; knowing them proves nothing.
• Sounds genuine — fraud calls are designed to sound genuine; a feeling is not a check.
• Ask a colleague — the answer does not depend on anyone's opinion; the OTP must never be shared.
Answer: Do not share the OTP and report the call as fraudulent
An OTP is like a signature — no genuine caller ever needs it. -

Choose the correct meaning of idiom given below:
"Pound of flesh"Answer: C) A harsh demand for rightful payment
The idiom 'pound of flesh' (from Shakespeare's The Merchant of Venice) means something that is owed and is ruthlessly insisted upon - a harsh demand for what one is strictly entitled to, even if it causes suffering.
It is not fair or generous (A), not a compromise (B), and not a gift (D); it stresses a merciless insistence on one's due. -

**Find the part of the sentence that contains an error**:
It was not until the second report (1)/ was leaked to the press (2)/ did the ministry issue (3)/ a formal clarification. (4)Answer: C) (3)
The construction 'It was not until …' should be followed by 'that' clause, not inverted auxiliary.
Correct: 'It was not until the second report was leaked to the press that the ministry issued a formal clarification.'
Hence the error is in part (3). -
