The RBI’s “Finances of Panchayati Raj Institutions (PRIs)” report analyzes data from 2.58 lakh Panchayats for 2020-21 to 2022-23, highlighting key findings. Panchayats heavily rely on grants (95%) due to limited own revenue sources like property taxes. Inter-state variations in devolution impact socio-economic outcomes. Inconsistent data poses challenges in assessing fiscal health. PRIs struggle with local tax revenue generation due to a limited tax base, administrative issues, and unclear guidelines. Revenue sources include Central and State government grants, and PRIs have the authority to impose taxes and fees.

As given,
∠BOC = 110^o
And, we know incentre of a triangle is a point where angle bisector of triangles meet.
So, which means ∠OCB =∠OBC
∠BOC +∠OCB+∠OBC = 180^o
⇒∠OCB + ∠OBC = 180^o − 110^o
⇒∠OCB +∠OBC = 70^o

Since, ∠ABC = 2∠OBC
∠ACB = 2∠OCB
So, ∠ABC+∠ACB = 2 × 70^o
⇒∠ABC + ∠ACB = 140^o
Now, in triangle ABC.
∠ABC +∠BAC +∠ACB = 180^o
⇒∠BAC  +140o = 180^o
⇒∠BAC = 180o − 140^o
⇒∠BAC = 40^o
Hence, the correct answer is 40^o.

In order for a plant to grow and thrive, it needs a number of different chemical elements. The most important are: Carbon, hydrogen and oxygen – Available from air and water and therefore in plentiful supply Nitrogen, phosphorus, potassium (a.k.a. potash) – The three macronutrients and the three elements you find in most packaged fertilizers.

Sulfur, calcium, and magnesium – Secondary nutrients

Boron, cobalt, copper, iron, manganese, molybdenum and zinc – Micronutrients

Following the common explanation, we get “7 seats are there to the left of C”.
Hence, option D is correct.
Final Arrangement:

Common Explanation:
References:
1. Two people are sitting between A and Z.
2. C sits fourth to the right of Z.
3. The number of people sitting to the right of A is the same as the number of people sitting to the left of Z.
4. The number of people sitting between A and C is the same as the number of people sitting between X and C.
5. X is an immediate neighbour of D, who sits on one of the ends.
6. The number of people sitting between D and C is the same as the number of people sitting between C and Y.
7. At most 25 people are sitting in a row.
Inferences:
From reference 1, we get two possible cases.
From reference 7, case2 was eliminated.
Hence, Case 1 is the final arrangement.

The correct answer is ALU.

• The part of the CPU that performs logical operations is called ALU.

​Important Points

• There are 2 parts of the CPU:
  • Arithmetic and logic unit (ALU)
  • Control Unit

Key Points

• The arithmetic and logic unit (ALU)
  • The arithmetic and logic unit (ALU) is where the CPU performs the arithmetic and logic operations.
  • Examples of arithmetic operations are addition, subtraction, multiplication, and division.
  • Examples of logic operations are comparisons of values such as NOT, AND, and OR.
  • The Control Unit carries out instructions.

Additional Information

• The central processing unit (CPU)
  • The computer's central processing unit (CPU) is the device of a computer that retrieves and executes instructions.

Muscular force is generated by the contraction of muscles and is responsible for various physical actions, such as walking, lifting, and pushing. When muscles contract, they exert force on bones and joints, enabling movement and physical activities. Muscular force is a type of contact force, as it involves direct interaction between muscles and other body parts. Understanding muscular force is crucial for biomechanics, sports science, and physical therapy, as it plays a significant role in human movement and performance.

Auxins are not specifically produced at the region of elongation. Instead, they are primarily synthesized in the apical meristems of the plant, particularly in the shoot apical meristem and young leaves. From there, auxins are transported downwards towards the region of elongation, where they play a crucial role in cell elongation and growth. So, while auxins are involved in the regulation of elongation, they are not produced exclusively at the region of elongation.

The flow of electrons is caused by the voltage, which is the disparity in electric potential between two points.

a = 3
d = a(2) – a(1)
⇒ 1 – 3 = -2
⇒ d = -2

Mizoram University’s zoology researchers identified a new coral snake species, naming it Sinomicrurus gorei after Dr. Gore. Locally called ‘Rulṭhihna,’ it resembles the traditional Mizo amber necklace ‘Ṭhihna.’ Only one other Sinomicrurus species, Sinomicrurus macclellandi, exists in Northeast India. Unique features, including scales, hemipenis, DNA, and skull, differentiate them. Previously considered the same species, a recent study unveiled distinctions. While Sinomicrurus macclellandi lays 6-14 eggs, Sinomicrurus gorei lays up to three, and their habitats differ in Mizoram.

Hence, Option C is correct.
