The correct answer is Ribonucleic Acid.

Key Points

• It is a polymer of nucleotides that is made up of a ribose sugar, a phosphate, and bases such as adenine (A), guanine (G), cytosine (C), and uracil (U).
• It has various biological roles in coding, decoding, regulation, and expression of genes.
• RNA is a nucleic acid messenger between DNA and ribosomes.
• Thymine (T) in DNA is replaced by uracil (U) in RNA.

Additional Information

• There are three main types of RNA –  rRNA (ribosomal), tRNA (transfer), mRNA (messenger).
• mRNA: It transcribes the genetic code from DNA into a form that can be read and used to make proteins.

mRNA carries genetic information from the nucleus to the cytoplasm of a cell.

• rRNA: It directs the translation of mRNA into proteins.
• tRNA: It brings or transfers amino acids to the ribosome that correspond to each three-nucleotide codon of rRNA. The amino acids then can be joined together and processed to make polypeptides and proteins.

On applying the above in each options.

Option 1: 18 × 6 - 4 + 7 × 8 = 47

After interchanging signs

⇒ 18 + 6 ÷ 4 × 7 + 8

⇒ 18 - 6 × 2 - 3

⇒ 18 - 12 - 3

⇒ 3 ≠ 22 (RHS)

Option 3: 18 + 6 - 4 × 2 ÷ 3 = 26

After interchanging signs

⇒ 18 × 6 ÷ 4 + 2 - 3

⇒ 18 × 1.5 + 2 - 3

⇒ 27 + 2 - 3

⇒ 26 = 26 (RHS)

Option 4: 18 - 6 × 7 ÷ 2 + 8 = 63

After interchanging signs

⇒ 18 ÷ 6 + 7 - 2 × 8

⇒ 3 + 7 - 16

Given:

 

Total initial volume of the mixture = 729 ml

 

Initial mixture ratio of milk to water = 7 ∶ 2

 

Desired mixture ratio of milk to water = 7 ∶ 3

 

Calculation:

 

Extract the quantity of milk and water from the initial mixture using the provided ratio.

 

⇒ Initial ratio (Milk : Water) = 7 ∶ 2

 

⇒ Total parts in the mixture = 7 parts (Milk) + 2 parts (Water) = 9 parts

 

⇒ Quantity of Milk = (7/9) × 729 ml = 567 ml

 

⇒ Quantity of Water = (2/9) × 729 ml = 162 ml

 

Determine the quantity of water required to achieve the desired mixture ratio. ⇒ Desired ratio (Milk : Water) = 7 ∶ 3

 

⇒ For 7 parts of milk, we need 3 parts of water ⇒ So, desired quantity of Water = (3/7) × 567 ml ≈ 243 ml

 

⇒ More Water to be added = Desired quantity of Water - Initial quantity of water

 

⇒ More Water to be added = 243 ml - 162 ml = 81 ml

 

Hence, the correct answer is "81ml".

The correct answer is 1992

• Panchayati Raj system was formalized in the year 1992 by the 73^rd Amendment to the Indian Constitution.
• Panchayati Raj is the oldest system of local government in the Indian subcontinent.
• Panchayati Raj Institutions as units of local government have been in existence in India for a long time, in different permutations and combinations.
• Panchayati Raj, which was inaugurated by the then Prime Minister Pandit Jawaharlal Nehru on 2 October 1959 at Nagaur in Rajasthan.
• The first elections under the Rajasthan Panchayat Samitis and Zilla Parishads Act, 1959 were held in September-October 1959.

Key Points

• Key Features of Panchayat Raj System are:
• The Gram Sabha is a body consisting of all the people registered in the electoral rolls who belong to a village comprised within the area of the Panchayat at the village level.
• Seats are reserved for Scheduled Castes (SCs) and Scheduled Tribes (STs) and chairpersons of the Panchayats at all levels are reserved for SCs and STs in proportion to their population.
• 50 percent of the total number of seats are to be reserved for women. One-third of the seats reserved for SCs and STs are also reserved for women.
• There is a uniform policy with each term being five years. Fresh elections must be conducted before the expiry of the term. In the event of dissolution, elections compulsorily within six months (Article 243E).
• Panchayats have the responsibility to prepare plans for economic development and social justice with respect to the subjects as per the law put in place, which also extends to the various levels of Panchayat including the subjects as illustrated in the Eleventh Schedule (Article 243G).

Important Points

• The Panchayati Raj Institution (PRI) consists of three levels:

Given:

 

Ratio 1: 17 ∶ 18

 

Ratio 2: 10 ∶ 11

 

Concept:

To compare two ratios, we can make the denominators of the two ratios equal by multiplying the first ratio by the LCM of 18 and 11 (which is 198) and the second ratio by the LCM of 18 and 10 (which is 180). The ratio with the larger numerator after the denominators are made equal is the greater ratio.

 

Solution:

 

Rewrite the two ratios with the LCM of the denominators:

 

Ratio 1: 17/18 × 11/11 = 187/198

 

Ratio 2: 10/11 × 18/18 = 180/198

 

Compare the numerators of the two ratios:

 

187 > 180

 

The ratio 17 ∶ 18 is greater than the ratio 10 ∶ 11.

 

Hence, the correct answer is 17:18.

Given:

 

Total value to be divided: 81

 

Concept:

 

This problem can be solved by setting up simultaneous equations based on the given conditions and then solving them.

 

Solution:

 

Let the three parts be x, y, and z. According to the given conditions, we have: ⇒ x/2 = y/3 = z/4

 

This implies the ratios of x, y, and z are 2, 3, and 4, respectively because x is half of some number, y is a third of that same number, and z is a quarter of that number hence x:y:z = 2:3:4.

 

We also know that the sum of the parts x, y, and z equals 81.

 

⇒ x + y + z = 81

 

We can calculate the total ratio,

 

⇒ Total Ratio = 2 + 3 + 4 = 9

 

The value of each ratio is given by: ⇒ Value of Each Part (p) = Total Value / Total Ratio ⇒ p = 81 / 9 = 9

 

Therefore, the three parts are:

 

⇒ x = 2 × 9 = 18 ⇒ y = 3 × 9 = 27 ⇒ z = 4 × 9 = 36

 

Hence, the three parts are 18, 27, and 36, respectively.
