Answer: B. Yerragudi Minor Rock Edict

The Ashokan Rock Edict found written partly in the Boustrophedon style is the Yerragudi Minor Rock Edict. The reasons for this are:

• Boustrophedon style refers to a writing style where alternate lines of text are reversed, with the direction of writing and reading alternating from left to right and then right to left. This style of writing was used in some ancient scripts, such as Greek and Etruscan.
• Yerragudi Minor Rock Edict, also known as the Gavimath inscription, is located in the Koppal district of Karnataka, India. It is one of the earliest inscriptions of Emperor Ashoka, dating back to the 3rd century BCE.
• The inscription is written in the Prakrit language using the Brahmi script, and it contains the early teachings of Buddhism, as well as the principles of Dhamma (righteousness).
• The Boustrophedon style can be observed in some parts of the Yerragudi Minor Rock Edict, making it the correct answer for this question.

The executive board of the International Monetary Fund (IMF) approved a proposal to make a 50 per cent increase in the quota allocated to members in proportion to their current quotas. The proposal will now be considered and made effective by the board of governors as part of concluding the 16th general review of quotas.
Currently, India has a quota of special drawing rights (SDR) 13,114.4 million which denotes a share of 2.75 per cent, making it the eighth-largest quota-holding country in the IMF.

The Indian Historical Records Commission (IHRC), operating under the Union Ministry of Culture, has adopted a new logo and motto. It is an apex advisory body on archival matters. It was established in the year 1919.

The Jammu & Kashmir government, under the leadership of LG Manoj Sinha, approved 10% reservation for Paharis and included 15 new castes in the Other Backward Classes (OBCs) category, signalling a move towards greater inclusivity in reservation policies.

Let α,β are the zeroes of the given polynomial.
Given: 
 ⇒ −(−27) = 3k² ⇒ k² = 0 ⇒ k= ±3

Diameter=14, Radius=d/2=14/2=7cm
Perimeter of the semi- circle= Boundary of the semi-circle =Circumference of the semi-circle +Diameter= πr+D=

Area of circle with radius R₁ = πR₁²
Area of circle with radius R₂ = πR₂²
Area of circle with radius R = πR²
Area of circle with radius R₁+Area of circle with radius R₂ =Area of circle with radius R
πR₁² + πR₂²=πR²
R₁²+R₂²=R²

Let p(x) =ax3 + bx2 + cx + d

Given that, one of the zeroes of the cubic polynomial p(x) is zero.

Let α, β and γ are the zeroes of cubic polynomial p(x), where α = 0.

We know that,

Step-by-step explanation:

sum of two zeros at a time = c/a

                      ∴αβ + βy + yα = c/a

                  ∴0×β + βy + y×0 = c/a

                                         βy = c/a

  hence, product of 2 zeros = c/a

Therefore, the correct answer is Option 1: 22 cm.

Number of possible outcomes = {2, 3, 5} = 3
Number of Total outcomes = 6
∴ Probability of getting a prime number = 3/6 = 1/2

2x² + 3 + 2√6x + x² = 3x² - 5x
3 + 2√6x + 5x= 0

Which is not a quadratic equation.

60°+ QSR=180°[co interior angles]

QSR=120°

RFE=QSR

So,RFE=120°

ABCD is a parallelogram and ∠ A = 72°

We know that opposite angles of a parallelogram are equal

∴ ∠A = ∠C and ∠B = ∠D

∴ ∠C = 72°

∠A and ∠B are adjacent angles

i.e., ∠A + ∠B = 180°

⇒ ∠B = 180° – ∠A

⇒∠B = 180° – 72° = 108°

∠B = ∠D =108°

Hence, ∠B = ∠D = 108° and ∠C = 72°

"The distance between the origin and the coordinates (2, 3) is

Square root of (2 – 0)^2 + (3 – 0)^2

Square root of 2^2 + 3^2

Square root of 4 + 9

Square root of 25

Hence 5 will be the total distance between the coordinates and origin.

In case of x-axis we will only consider the value of y coordinate that is 3.

The probability of a sure event is always 1.

Triangle, square and rhombus are shapes. Tangent is not.

The answer is B: Eagle.

Explanation:
Kiwi, Emu, and Ostrich:
- These are all flightless birds.

Eagle:
- Eagles are powerful birds of prey.
- They have strong wings and are capable of flight.
- They belong to the family Accipitridae, which includes hawks, kites, and harriers.
Conclusion: The word that is different from the rest is B: Eagle, because it is a bird of prey capable of flight, while the others are flightless birds.
