Let, the measure of the required angled be A°.
Then, measure of its complement = ( 90 – A )° measure of its supplement = (180 – A)°
According to question,
6(90° – A) = 2(180° – A) –12°
⇒ 540° – 6A = 360° – 2A – 12°
⇒ 4A = 192°
⇒ A = 48°.

Statement 1 is incorrect because the Montagu-Chelmsford Reforms introduced dyarchy in provinces, which meant control was divided between elected Indian ministers and appointed British officials, not completely transferred to Indian hands. Statements 2 and 3 are correct as the Rowlatt Act did allow detention without trial to curb seditious activities, and the Jallianwala Bagh Massacre was indeed a direct result of the protests against the arrest of nationalist leaders Saifuddin Kitchlew and Dr. Satyapal.

Rashtrakuta king, krishna-1 had built the kailash temple of ellora. It is considered as the wonder of rock-out architecture.

Let the numerator = x and denominator = y

y + 3 = 2y ⇒ y = 3

x +1= 3 ⇒ x = 2

∴ xy = 2 × 3 = 6

Let the total length of the tree be X + Y meters
From the figure tan 45 = X/20 => X = 20
cos 45 = 20/Y => Y = 20/cos 45 = 20√2
X + Y = 20 + 20radic; 2 = 20 + 2 x 10 x 1.414 = 48.28 meters

r% of r = 49
r² = 49 × 100
r = 7 × 10 = 70
Hence, Option B is correct.

The correct answer is B  as the correct match is given in option B .

The correct answer is Himachal Pradesh.

• Himachal Pradesh shares its boundary with Haryana.

Key Points

• Haryana is a state in the northern region of India with 22 districts.
  • The State borders Punjab and Himachal Pradesh to the north and Rajasthan to the west and south.
  • The river Yamuna defines its eastern border with Uttarakhand and Uttar Pradesh.

Additional Information

• Haryana also surrounds Delhi on three sides, forming the northern, western and southern borders of Delhi.
• Consequently, a large area of Haryana is included in the National Capital Region.

Let AB be the observation tower and h be its height.

Also, let the ship be at C when the angle of elevation is 30° and at D when the angle of elevation is 45°.

The time taken by the ship to travel from C to D is 10 minutes and we need to find out the time the ship will take to reach B from D.

∴ tan 30º = AB/CB = h / CB = 1/ √3

⇒ CB = √3 x h

∴ tan 45º = AB / DB = h / DB = 1

⇒ DB = h

⇒ CD = CB – DB = (√3h – h) = h(√3– 1)

Now, as h(√3 – 1) distance is covered in 10 minutes, a distance of h is covered in = 13.66 minutes = 13 minutes 40 seconds

Let the required number be x.
As given,

Given, 3, 8, 13, 18, … is the AP.
a = 3
d = a(2) – a(1) = 8 − 3 = 5
Let a(n) term be 78.
a(n) = a + (n − 1) x d
78 = 3 + (n − 1) x 5
75 = (n − 1) x 5
(n − 1) = 15
n = 16

Length of the rectangle = 5x
Breadth of the rectangle = 4x
5x × 4x = 320
x² = 16
x = 4
So the answer = 2 × (5x + 4x) = 2 × 9x = 2 × 9 × 4 = 72 cm
Hence, Option B is correct.

• Chautang river originates from the foothills of Shivalik in Himachal Pradesh.
• It serves as the seasonal river in Haryana.
• According to vedic age it was termed as Drishadvati river where Indus-Sarasvati civilization grew.

• It was prepared by an All Parties Conference chaired by Motilal Nehru with his son Jawaharlal Nehru acting as secretary.

• There were nine other members of this committee. The final report was signed by Motilal Nehru, Ali Imam, Tej Bahadur Sapru, Madhav Shrihari Aney, Mangal Singh, Shuaib Qureshi, Subhas Chandra Bose, and G. R. Pradhan. Qureshi disagreed with some of the recommendations.

Some of the important elements of the report.

• Unlike the eventual Government of India Act 1935, it contained a Bill of Rights.

• All power of government and all authority - legislative, executive and judicial-are derived from the people and the same shall be exercised through organisations established by, or under, and in accord with, this Constitution.

• There shall be no state religion; men and women shall have equal rights as citizens.

• There should be a federal form of government with residuary powers vested in the centre. (Some scholars, such as Moore 1988 considered the Nehru Report proposal as essentially unitary rather than federal);

• It included a description of the machinery of government including a proposal for creating a Supreme Court and a suggestion that the provinces should be linguistically determined.

• It did not provide for separate electorates for any community or weightage for minorities. Both of these were liberally provided in the eventual Government of India Act 1935.

• However, it did allow for the reservation of minority seats in provinces having a minority of at least 10%, but this was to be in strict proportion to the community's size.

• The Union's language shall be Indian, which may be written either in Devanagari (Hindi/Sanskrit), Telugu, Kannada, Marathi, Gujarati, Bengali or Tamil in character. The use of the English language shall be permitted.
