Correct Answer : C

Unrolled flat, a cone's curved surface is a sector of a circle of radius \( l \) whose arc is the base circumference \( 2\pi r \). Its area is

\[ \text{CSA} = \frac{1}{2} \times \text{arc} \times \text{radius} = \frac{1}{2} \times 2\pi r \times l = \pi r l \]

The total surface area adds the circular base:

\[ \text{TSA} = \pi r l + \pi r^{2} = \pi r (l + r) \]

Note that the slant height \( l \) is used here, not the perpendicular height \( h \); the two are related by \( l^{2} = r^{2} + h^{2} \).

Correct Answer : A

Write the condition algebraically.

\[ A + B = (B + C) + 12 \]

The \( B \) cancels from both sides:

\[ A - C = 12 \]

So C is 12 years younger than A. B's age never matters - which is why it is not given.

Correct answer: 45

A full-duplex line serves both directions, and no station connects to itself, so the number of connections is the number of unordered pairs:

\[ \binom{10}{2} = \frac{10\times 9}{2} = 45 \]

Correct answer: Page Setup dialog box

Vertical alignment - whether text sits at the top of the page, in the centre, or is justified down its height - is a property of the page, and is set on the Layout tab of Page Setup. The paragraph dialog controls horizontal alignment instead.

Correct Answer : C

Correct answer: Margin that is added to the binding side of page when printing

The gutter is the extra space allowed for the binding, so that text is not swallowed in the fold. On single-sided printing it is added on the left; with mirror margins it alternates between left and right, which is why it is defined by the binding rather than by a side.

EV Ramaswamy Periyar started the movement for a separate Dravida Nadu for the Dravidian people of the South, through the Self-Respect Movement and later the Dravidar Kazhagam. MG Ranade was a Maharashtra social reformer; A Ramaswamy Mudaliar was a Justice Party leader and administrator, not the founder of this demand; M Karunanidhi became prominent after Independence, so he cannot have started a pre-Independence movement.

The Upanishads mark the concluding part of Vedic literature.

Each Veda has four layers: the Samhitas (hymns), the Brahmanas (ritual texts), the Aranyakas (forest treatises) and the Upanishads (philosophical texts). Because the Upanishads come at the end, they are called Vedanta, the end of the Veda.

They are not the introductory or middle part; the Samhitas begin the corpus. 'Foreward' is not a part of it.

Correct Answer : C

The ionised layers of the upper atmosphere are dense enough to burn up falling meteorites by friction long before they reach the surface, which is why most are seen only as brief streaks of light.

Ultraviolet radiation is absorbed lower down, by the ozone layer in the stratosphere, and infrared is largely trapped by water vapour and carbon dioxide in the troposphere.

All three statements are correct, so the answer is 1, 2 and 3.

The 720 MW Mangdechhu project in Trongsa district of central Bhutan is a run-of-river plant built with Indian assistance (1). The 600 MW Kholongchu project is the first India-Bhutan joint venture hydropower project, executed by Kholongchu Hydro Energy Limited, a joint venture of India's SJVN and Bhutan's Druk Green Power Corporation (2).

The Chukha, Kurichhu and Tala projects are the earlier hydropower projects built under India-Bhutan bilateral cooperation and already in operation (3). Since all three hold, every narrower option is incomplete.

The theme was Path to Pride.

DefExpo 2022, the 12th edition of India's land, naval and homeland security exhibition, was held at Gandhinagar, Gujarat, in October 2022 with the theme 'Path to Pride'. It was the first edition limited to Indian companies, in line with the push for self-reliance in defence.

'India: The Emerging Defence Manufacturing Hub' was the theme of DefExpo 2020 in Lucknow. 'Synergy for Defence' and 'Aatmanirbharta' alone were not the 2022 theme.
