Kepler’s Laws of Planetary Motion describe the orbits of planets around the sun. They state that planets move in elliptical orbits with the sun at one focus, among other things.

In this reverse alphabet code, ‘K’ is written as ‘P’, ‘I’ as ‘R’, ‘L’ as ‘O’. So, ‘KILL’ is coded as ‘PKOO’.

The sentence should use “work” instead of “works” because “Neither of” is followed by a plural noun, thus requiring a plural verb. Correct sentence: “Neither of the solutions work.”

Speed of the second train = 400 km / 4 hrs = 100 km/hr. Using the ratio of speeds, 3:4, speed of the first train = 3/4 × 100 = 75 km/hr.

Baking soda is the common name for Sodium Bicarbonate (NaHCO3). It is widely used in baking as a leavening agent.

The Chipko Movement in India, known for its strategy of hugging trees to prevent deforestation, drew significant inspiration from a similar movement in Japan. The Japanese movement involved protests against deforestation and emphasized harmony with nature, influencing the non-violent approach of the Chipko activists.

Original area = πr². New radius = 1.2r. New area = π(1.2r)² = 1.44πr². The percentage increase in area = (1.44πr² – πr²) / πr² × 100% = 44%.

Since B is E’s parent and A’s sibling, and C is A’s parent, C is E’s (and therefore D’s) grandfather.

Megasthenes was an ancient Greek historian and diplomat who wrote the account ‘Indica’ based on his stay in India. He was an envoy to the court of Chandragupta Maurya, the founder of the Maurya Empire, and his writings provide valuable insights into early Indian history and society.

Raj ends up 5m west of his original position, as his north and south movements cancel each other out.

Volume of a cylinder = πr²h = π * 5² * 2 = 50π m³.

Both the length and the width of the rectangle are necessary to calculate its area, as the area of a rectangle is given by the product of its length and width.

Both the assertion and the reason are true. However, the reason R is not the correct explanation of A. While a passport is necessary for international travel, it being proof of nationality is not the reason for its necessity in travel.

Let original length = l and breadth = b. New length = 1.2l, new breadth = 1.3b. New area = 1.2l * 1.3b = 1.56lb. Increase = 1.56lb – lb = 0.56lb, which is a 56% increase.

The most logical inference is that the flooding caused significant damage, prompting the government to announce relief measures. The other options are assumptions beyond the provided information.

The most direct implied outcome of requiring all public transport vehicles to be electric is an increase in electricity consumption (Option B). The other options, while possible, are more indirect and speculative.

The relative speed = 60 km/hr – 40 km/hr = 20 km/hr = 20 * (1000/3600) m/s = 5.56 m/s. Let the length of the first train be L meters. Then, the second train’s length is L/2 meters. The total distance covered in overtaking = L + (L/2) = 1.5L meters. Time taken = 30 seconds. So, 1.5L = 5.56 * 30, giving L ≈ 200 meters.

Side of the triangle = Perimeter/3 = 18/3 = 6 cm. Area of an equilateral triangle = (√3/4) * side² = (√3/4) * 6² = 17.320 cm².

If the cost price is ₹100, the marked price is ₹120. A 10% discount on ₹120 is ₹12, so the selling price is ₹108. The gain is ₹108 – ₹100 = ₹8, which is an 8% gain.

A’s 1 day’s work = 1/10, B’s 1 day’s work = 1/15. Together, in 4 days, they complete 4*(1/10 + 1/15) = 2/5 of the work. Remaining work = 1 – 2/5 = 3/5. A will complete this in 3/5 * 10 = 6 more days.

Area of the square = 30 cm × 30 cm = 900 cm². Let the breadth of the rectangle be x cm. Length = 1.2x cm. Area = x × 1.2x = 900 cm². Solving for x gives x ≈ 27 cm, so the length is 1.2 × 27 ≈ 32.4 cm.

The assumption made in the argument is that flexible working hours will lead to increased productivity. It implies a direct correlation between flexible hours and productivity improvements.

Gain or loss is calculated on cost price. Let the cost price of the first watch be x and the second y. 105% of x = 95% of y = ₹2000. The overall loss = (Selling price of both – Cost price of both) = 4000 – (x + y). Calculating x and y and then the difference shows a 0.25% loss overall.

A ‘Pen’ is used to ‘Write’; similarly, a ‘Brush’ is used to ‘Paint’.

Conclusion I is not necessarily true as there’s no direct link between mangoes and sour things. Conclusion II is also not valid as the statement does not negate mangoes being sour. Therefore, neither conclusion follows.

Let the number be x. 35% of x = 175, so x = 175 * 100 / 35 = 500. 50% of 500 = 250.

Area of a parallelogram = base * height. Let the base be x cm. Then, x * 15 = 180. Solving for x gives x = 12 cm.

Each letter is assigned a unique number based on its position in ‘OPTICAL’. Using the same coding, ‘TOPICAL’ is coded as ‘3124567’.

While heavy rain might cause flooding, flooding can also be caused by other factors like poor drainage. Therefore, we cannot definitively infer that it has rained heavily.

“English is spoken all over the world by people” is the correct passive form. The active voice ‘speak’ (present simple) changes to ‘is spoken’ (present simple passive) in passive voice. Example: “Spanish is spoken widely in South America.”

The Battle of Plassey was fought in 1757 between the British East India Company and the Nawab of Bengal, Siraj ud-Daulah. It marked the beginning of British rule in India.

The pattern involves increasing the first letter by one, replacing the middle letter with a number representing the number of letters, and keeping the last letter the same. So, ‘fish’ becomes ‘g5h’.

Pattachitra, characterized by its intricate details and mythological narratives, is a traditional cloth-based scroll painting style native to Odisha, India. It is known for its vibrant colors and motifs and is closely related to the worship of Lord Jagannath.

“John, who is an engineer, is my friend.” is correctly punctuated. The commas are used to set off the non-restrictive clause “who is an engineer,” which provides extra information about John. Example: “My brother, who lives in New York, is visiting.”

The first two and last two letters of ‘RIVER’ are reversed. Applying the same rule, ‘OCEAN’ becomes ‘COEAN’.

Insulin, a hormone produced by the pancreas, plays a key role in regulating blood sugar levels. It allows cells to absorb glucose from the blood for energy.

The passage indicates that financial literacy includes understanding how to budget, save, invest, and manage debt, which are all aspects of managing personal finances effectively, making “All of the above” the correct answer.

“Cogent” is the correct choice. It means clear, logical, and convincing, which aligns with an argument based on facts and logical reasoning. Example: “She made a cogent argument for the adoption of renewable energy sources.”

The passage defines the Baroque period by “elaborate and detailed style,” “dramatic use of light and color,” and “emphasis on motion and contrast,” making “All of the above” the correct option.

Bhutan uses ‘Gross National Happiness’ as a measure of its development, a concept introduced by its former King Jigme Singye Wangchuck. It focuses on sustainable and holistic development rather than just economic growth.

The most directly implicit assumption in the advertisement is that people want their clothes to last longer (Assumption B). The advertisement suggests this benefit to attract customers. Assumption A is a marketing claim, not necessarily an implicit assumption of the statement.

Let the cost price be ₹x. Selling price = x + 20% of x = 1.2x = ₹816. Solving gives x = ₹680.

ISRO’s Chandrayaan-2 mission aimed to explore the south polar region of the Moon. This mission was significant for its attempt to study a region of the Moon not previously explored in detail.

Since PQ = QR, ΔPQR is isosceles. The angles opposite the equal sides are equal, so ∠QRP = ∠QPR. Let each of these angles be x. Then, x + x + 100° = 180° (sum of angles in a triangle). Solving gives x = 40°.

Total surface area of a cube = 6 * side². 216 = 6 * side², giving side² = 36, so the side = 6 cm.

Milk = (7/10) * 30 = 21 litres, Water = 9 litres. Let x litres of water be added. New ratio = 21 : (9+x) = 3 : 7. Solving gives x = 14 litres.

The Battle of Hydaspes in 326 BC was fought between Alexander the Great and King Porus, one of the most powerful Indian rulers of his time. The battle took place on the banks of the Hydaspes River (now the Jhelum River in Pakistan) and is notable for the respect Alexander developed for Porus for his bravery and leadership.

Neither conclusion necessarily follows from the statements. The first conclusion is a misinterpretation of the relationship, and the second conclusion is not directly supported by the given information.

‘Cube’ is the odd one out as it is a 3-dimensional shape, while the others are 2-dimensional polygons.
