Correct Answer : D

The value of 3p - 50° is 190°.

Supplementary angles add up to 180°. With the larger angle L and the smaller p:

\[ \begin{aligned} L + p &= 180^{\circ},\quad L - p = 20^{\circ} \\ 2p &= 160^{\circ} \Rightarrow p = 80^{\circ} \\ 3p - 50^{\circ} &= 240^{\circ} - 50^{\circ} = 190^{\circ} \end{aligned} \]

Using the larger angle (100°) gives 250°, option C. 310° and 270° do not come from either angle.

Correct Answer : C

Let A be the set for apple juice and O for orange juice.

n(A) = 100, n(O) = 150, n(A ∩ O) = 75.

Number of students drinking at least one juice = n(A ∪ O) = n(A) + n(O) - n(A ∩ O) = 100 + 150 - 75 = 175.

Total students = 400.

Number of students drinking neither = Total - n(A ∪ O) = 400 - 175 = 225.

Correct Answer : A

The appropriate inference is there is a strong correlation between crow birth and cracker sales.

The two series move together year by year: flat from 2002 to 2004, a spike in 2005 and a fall afterwards. That is a strong correlation. But the question itself says the studies are unrelated, and nothing in the data shows a mechanism linking crows and crackers.

So the data support only the statement of correlation. Saying crackers increase crow births, or that crow births cause cracker sales, claims causation, and predicting that a fall in cracker sales will reduce crow births assumes the same causal link. Correlation alone does not establish any of these.

The missing number is 113. The series adds a square and a cube alternately: \[ 6 + 1 = 7 \] \[ 7 + 2^{3} = 15 \] \[ 15 + 3^{2} = 24 \] \[ 24 + 4^{3} = 88 \] \[ 88 + 5^{2} = 113 \] \[ 113 + 6^{3} = 329 \] The last step reaches the given 329 exactly, which confirms the pattern. The other options 114, 115 and 116 would leave a gap that is not 216, so the final cube would not fit. Checking the last step shows that 113 + 216 = 329, which agrees with the number given in the series.

Correct Answer : A

The phrase means Her fame grew.

If something spreads far and wide, it reaches a great many places and people. Her fame spreading far and wide means it grew and became widely known, which fits the reason given: she was a talented singer.

The phrase says nothing about her fame lessening or ending, and it describes fame that already existed, not fame that was just beginning.

For example: 'News of the discovery spread far and wide within a week.'

Correct Answer : D

The correct preposition is with: familiar with this locality.

A person is familiar with a thing, place or subject they know well: 'He is familiar with the rules'. The other construction reverses the roles: a thing is familiar to a person, as in 'This locality is familiar to him'.

Since the subject here is the person ('He'), 'to' is wrong. 'Familiar from' and 'familiar about' are not idiomatic.

Both patterns can describe the same situation: 'He is familiar with this locality' and 'This locality is familiar to him' mean the same.

Correct Answer : C

Correct answer: a process references a page that is not currently in physical memory

A page fault is raised when a process references a page whose valid bit in the page table indicates it is not resident in physical memory. Servicing it follows a fixed sequence: the hardware traps to the operating system, which checks that the reference is legal, finds a free frame or selects a victim to evict, writes the victim back if it is dirty, reads the required page in from the backing store, updates the page table, and restarts the instruction that faulted. It is not an error, despite the name. Demand paging depends on page faults as its ordinary mechanism, and a process starts with none of its pages resident, faulting them in as it runs. The cost is what matters: a memory access takes nanoseconds and a disk access milliseconds, so the effective access time is dominated by the fault rate. A rate of one in a hundred thousand can still double the average access time, which is why locality of reference is essential to the scheme working at all.

Correct answer: Landscape

Word offers exactly two orientations: Portrait, taller than it is wide, and Landscape, wider than it is tall. Portrait is the default. Landscape is chosen for wide tables, charts and timelines that would not otherwise fit across the page. The practical point worth knowing is how to mix the two. Orientation is a section property, so a single landscape page inside a portrait document requires a section break before and after it - a Next Page break in each case - after which the orientation of that section alone can be changed. Simply selecting the page and changing orientation does not work without them. Orientation is set from the Layout tab, alongside margins, paper size and columns. It also affects headers and footers, which reflow to the new width, and can require the page numbering to be checked afterwards.

The folk dance of the Sahariya tribe is the Shikar dance.

The Sahariyas, who live mainly in Baran district (Shahabad and Kishanganj), are counted among Rajasthan's most primitive tribes. Their shikar (hunting) dance enacts a hunt and is the dance associated with the tribe.

The Chari dance, in which women balance brass pots with burning lamps on their heads, belongs to the Gujjar community of Kishangarh. Machli and Jhumar are not the Sahariya dance asked about.

Bhuri Bai of Pitol is associated with painting.

Bhuri Bai, from Pitol village in Jhabua district, is a Bhil artist, the first woman of her community to paint on paper and canvas. Her Pithora-inspired paintings of Bhil life and myth are exhibited at Bharat Bhavan and elsewhere, and she received the Padma Shri in 2021.

She is not a singer, dancer or dramatist, so the other options are wrong.

Section 17(3) of the Right to Information Act, 2005 lets the Governor remove the State Chief Information Commissioner by order if he is adjudged an insolvent, is convicted of an offence involving moral turpitude, engages in paid employment outside his duties during his term, is in the Governor's opinion unfit to continue because of infirmity of mind or body, or acquires financial or other interests likely to affect his functions prejudicially.

Each of the four listed circumstances is in that section, so every option that drops one of them is incomplete.

The incorrect statement is that platelets contain DNA.

They have no nucleus, being fragments budded off from megakaryocytes in the marrow. The rest is true: they are roughly disc-shaped, about 2 to 3 micrometres across against the red cell's 7, and synthesise very little protein.

This is the law of multiple proportions.

Carbon combines with oxygen in two ratios: 12 g of carbon with 16 g of oxygen gives CO, and 12 g with 32 g gives \(\mathrm{CO_2}\). For a fixed mass of carbon, the masses of oxygen are in the simple whole-number ratio \(16:32 = 1:2\), which is exactly what Dalton's law states.

The bat uses sound as its eyes. It emits ultrasonic pulses and builds a picture of its surroundings from the returning echoes - a process called echolocation.

The technique is precise enough to catch a flying insect in total darkness. Dolphins and some whales use it in water; owls hunt by acute hearing but do not emit sound of their own.

Correct answer: Jupiter

Jupiter’s magnetic field is about twenty thousand times stronger than the Earth’s and is by far the largest structure in the solar system after the Sun’s own heliosphere - if its magnetosphere were visible from Earth it would appear several times the width of the full Moon. The field is generated by a dynamo in a deep layer of metallic hydrogen, hydrogen compressed so hard by the planet’s gravity that it conducts electricity like a metal. Rapid rotation, under ten hours, drives the dynamo hard. Its radiation belts are correspondingly fierce, intense enough to damage spacecraft electronics, which is why probes such as Juno fly highly elliptical orbits that limit their time in the worst of it. Saturn has a similar but weaker field, Neptune’s is oddly tilted and offset from its centre, and Earth’s is the weakest of the four.

Correct answer: The Caspian Sea

The Volga flows about 3,530 km through western Russia and empties into the Caspian Sea, the largest enclosed body of water on Earth. Because the Caspian has no outlet to the ocean, the Volga is an endorheic river - its water leaves the basin only by evaporation. It supplies the great majority of the Caspian’s inflow, so changes in its discharge move the sea’s level directly. It is central to Russian history and identity, called Mother Volga, and its basin holds a large share of the country’s population and industry. Canals link it to the Baltic, the White Sea, the Black Sea and the Sea of Azov, making it the spine of Russia’s inland waterway network. The Danube, the second longest river in Europe, flows the other way into the Black Sea.
