Explanation: The Treaty of Yandabo was signed on 24 February 1826. It marked the official conclusion of the First Anglo-Burmese War. According to this treaty, the Burmese King ceded Assam, Manipur, Rakhine (Arakan), and the Taninthayi (Tenasserim) coast south of the Salween River to the British East India Company. This historic event led to the formal annexation of Assam by the British.
Explanation: The Brahmaputra river flows through the heart of Assam and is fed by numerous tributaries from both the north bank (Himalayas) and the south bank (Meghalaya plateau, Naga hills).
Key North Bank Tributaries: Subansiri, Kameng, Dhansiri (North), Manas, Teesta.
Key South Bank Tributaries: Kopili, Dhansiri (South), Dihing, Disang, Dikhow.
Among the south-bank tributaries, Dhansiri (South) is considered the most significant and largest in terms of basin area and volume. It originates in the Naga Hills and flows through Golaghat.
Explanation: The Umananda Temple, dedicated to Lord Shiva, is situated on the Peacock Island in the middle of the river Brahmaputra in Guwahati. It was built by the powerful Ahom King Gadadhar Singha in the year 1694 AD. The island is renowned for being the smallest inhabited riverine island in the world.
Explanation: In the Indian Constitution, Article 280 provides for the establishment of a Finance Commission by the President of India. Its primary duty is to recommend the distribution of financial resources (tax revenues) between the Union government and the State governments.
Additional Context: Article 315 deals with the UPSC, Article 324 deals with the Election Commission, and Article 356 relates to State Emergency (President's Rule).
Explanation: The Tropic of Cancer (23.5° N latitude) passes almost midway through the country, dividing India roughly into two halves: the tropical zone in the south and the sub-tropical zone in the north. It passes through 8 Indian states: Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura, and Mizoram.
Explanation: On January 1, 2024, the BRICS intergovernmental organization officially expanded. Alongside the original members (Brazil, Russia, India, China, South Africa), five new nations joined the bloc: Egypt, Ethiopia, Iran, Saudi Arabia, and the United Arab Emirates (UAE). Argentina was invited but formally declined to join following a change in its government.
Explanation: The Nobel Prizes in Physics, Chemistry, Physiology or Medicine, and Literature are awarded in Stockholm, Sweden by various Swedish academies. However, it is a crucial distinction that the Nobel Peace Prize is uniquely awarded in Oslo, Norway by the Norwegian Nobel Committee.
Explanation: The pancreas functions as both an exocrine and endocrine gland. Its endocrine cells (Islets of Langerhans) secrete Insulin and Glucagon. Insulin lowers blood sugar levels by facilitating cellular uptake of glucose, while glucagon raises it. A deficiency or resistance to insulin leads to Diabetes Mellitus.
Explanation & Step-by-Step Breakdown:
For any two positive integers, the product of the two numbers is strictly equal to the product of their Highest Common Factor (HCF) and Least Common Multiple (LCM).
Formula:
Number 1 × Number 2 = HCF × LCM
HCF = 12
LCM = 144
Number 1 = 36
Let the other number be 'x'.
36 × x = 12 × 144
x = (12 × 144) / 36
x = 144 / 3 (Since 36/12 = 3)
x = 48
Therefore, the other number is 48.
Explanation & Step-by-Step Breakdown:
Given: SP = ₹840, Profit Percentage = 20%
The Cost Price is always considered as the base, i.e., 100%.
Therefore, Selling Price = Cost Price (100%) + Profit (20%) = 120% of CP.
120% of CP = ₹840
(120 / 100) × CP = 840
CP = (840 × 100) / 120
CP = 84000 / 120
CP = 700
Therefore, the cost price of the article was ₹700.
Explanation & Step-by-Step Breakdown:
The Total Surface Area (TSA) of a right circular cylinder includes the Curved Surface Area (CSA) plus the area of the two circular bases (top and bottom).
Formula:
TSA = 2πr(r + h)
Radius (r) = 7 cm
Height (h) = 10 cm
π = 22/7
TSA = 2 × (22/7) × 7 × (7 + 10)
Cancel the 7s in the numerator and denominator:
TSA = 2 × 22 × (17)
TSA = 44 × 17
TSA = 748 sq cm
Therefore, the total surface area is 748 sq cm.
Explanation & Step-by-Step Breakdown:
Time taken by A = 15 days ➔ A's 1-day work = 1/15
Time taken by B = 20 days ➔ B's 1-day work = 1/20
(A + B)'s 1-day work = (1/15) + (1/20)
LCM of 15 and 20 is 60.
(A + B)'s 1-day work = (4/60) + (3/60) = 7/60
Total time taken = Reciprocal of combined 1-day work
Total time = 60 / 7 days.
Converting to a mixed fraction: 60 ÷ 7 = 8 with a remainder of 4.
Total time = 8(4/7) days.
Explanation & Step-by-Step Breakdown:
A = P(1 + R/100)^TWhere A = Amount, P = Principal, R = Rate of Interest, T = Time period in years.
A = 2420, P = 2000, T = 2 years.
2420 = 2000 × (1 + R/100)²
2420 / 2000 = (1 + R/100)²
121 / 100 = (1 + R/100)²
Taking the square root on both sides:
√(121/100) = 1 + R/100
11/10 = 1 + R/100
R/100 = (11/10) - 1
R/100 = 1/10
R = 100 / 10 = 10%
The rate of compound interest is 10% per annum.
Explanation & Step-by-Step Breakdown:
Total age of 30 students = Number of students × Average age
Total = 30 × 15 = 450 years.
New number of people = 30 + 1 (teacher) = 31 people.
New average age = 15 + 1 = 16 years.
New Total age = 31 × 16 = 496 years.
Teacher's age = New Total Age - Initial Total Age
Teacher's age = 496 - 450 = 46 years.
Explanation & Step-by-Step Breakdown:
Observe how each number transitions to the next.
5 × 2 = 10; 10 + 1 = 11
11 × 2 = 22; 22 + 1 = 23
23 × 2 = 46; 46 + 1 = 47
47 × 2 = 94; 94 + 1 = 95
The established mathematical rule is:
(Previous Term × 2) + 1Therefore, Next Term = (95 × 2) + 1 = 190 + 1 = 191.
Explanation & Step-by-Step Breakdown:
Write down the letters and map their alphabetical shifts:
W (+2) ➔ Y
A (+2) ➔ C
T (+2) ➔ V
E (+2) ➔ G
R (+2) ➔ T
The logic is a forward shift of +2 for every letter.
F (+2) ➔ H
I (+2) ➔ K
R (+2) ➔ T
E (+2) ➔ G
The coded word is HKTG.
Explanation & Step-by-Step Breakdown:
Statement: "That boy's father is my father's son."
Since the speaker clearly states "I have no brother or sister", he is an only child. Therefore, "my father's son" can only be the speaker himself.
Substitute the finding from Step 2 back into the original statement: "That boy's father is [me]."
This means the speaker is the father of the boy in the photograph. Thus, the photograph is of his son.
Explanation & Step-by-Step Breakdown:
Let the starting point be 'O'.
He walks 10 km North to reach point 'A'. (OA = 10 km)
From 'A', he walks 6 km South along the same path to reach point 'B'.
Now, distance from O to B is (10 - 6) = 4 km North of the starting point.
From 'B', he walks 3 km East to reach final point 'C'. (BC = 3 km)
We have a right-angled triangle OBC where OB = 4 km and BC = 3 km. We need to find the hypotenuse OC.
OC² = OB² + BC²
OC² = (4)² + (3)² = 16 + 9 = 25
OC = √25 = 5 km.
Point C is situated North and East relative to the origin point O. Therefore, the direction is North-East.
Final Answer: 5 km, North-East.
Image Placement: Explanation
Image Purpose: Visual aid to show the path taken and the formation of the right-angled triangle for distance calculation.
Exact AI Image Prompt: A clean, educational diagram showing directional vectors on a compass grid. A starting point 'O'. A line going North to 'A' (10km), then a line doubling back South to 'B' (leaving a 4km gap from O). Then a line going East from 'B' to 'C' (3km). A dashed line connecting 'O' and 'C' forms the hypotenuse of a right-angled triangle. Labels for 4km, 3km, and 5km on the respective sides.
Explanation & Step-by-Step Breakdown:
- "Dogs" and "Cats" are entirely separate classes of entities. No dog is a cat, and no cat is a dog. Therefore, their representing circles must not intersect.
- Both Dogs and Cats fall completely under the universal category of "Animals".
- Hence, the correct visual representation is one large master circle (Animals) that fully encloses two smaller, non-intersecting circles (Dogs and Cats). This corresponds to Option B.
Explanation & Step-by-Step Breakdown:
To arrange these words logically, we must follow the sequence of events in a standard legal/criminal process.
1. First, a Crime (3) is committed.
2. Following the crime, the Police (1) arrive and investigate or arrest.
3. The accused is then presented before a Judge (4).
4. The Judge listens to the case and delivers a Judgment (5).
5. Based on the judgment, a Punishment (2) is served.
Correct Sequence: 3, 1, 4, 5, 2.
Explanation: The word "Diligent" refers to a person who is exceptionally careful and uses a lot of effort in their duties. Therefore, the closest synonym among the options provided is Hardworking. Words like "Lazy" and "Careless" are antonyms.
Explanation: "Obvious" means something that is easily perceived or understood; clear, self-evident, or apparent. The exact antonym (opposite meaning) would be a word that means unclear or hidden. Obscure fits this definition perfectly. "Clear", "Visible", and "Transparent" are synonyms or related terms.
Explanation: In standard English grammar rules concerning adjectives and prepositions, you are "angry with" a person, but you are "angry at" or "angry about" a situation or an action. Since "the employee" is a person, the correct preposition is "with".
Explanation: The grammatical error lies in part B ("have brought").
Rule: The distributive pronouns 'Neither of', 'Either of', 'Each of', etc., are always followed by a plural noun/pronoun, but they strictly take a singular verb because they refer to subjects individually, not collectively.
Correction: The correct sentence should read: "Neither of the two boys has brought his book to the class today."
Explanation: The original sentence is in the Present Continuous Tense (Subject + is/am/are + V1+ing + Object).
When converting to passive voice, the structure changes to: Object + is/am/are + being + V3 (Past Participle) + by + Subject.
Therefore, "is repairing" correctly becomes "is being repaired". Option C perfectly reflects this grammatical transformation.
