Question Discussion & Solution

Elements of diagram are moving in clockwise direction and 1 dot is added in each step.

The complete diagram is as follows,

The correct answer is Fructose.

Key Points

•  Fructose
  • It is naturally occurring sugar.
  • It is the sweetest sugar.
  • It is a 'monosaccharide', meaning the simplest form of sugar, which means it cannot be broken down into more basic sugar units.
  • Other common examples of monosaccharides are glucose and galactose.
  • The chemical formula of fructose is C₆H₁₂O₆.

Additional Information

• Maltose
  • It is also a sweet sugar which is also known as maltitol sugar.
  • It is mostly found in honey.
  • Its molecular formula is C₁₂H₂₂O₁₁.
• Glucose
  • It is the most abundant monosaccharide, a carbohydrate sub-category.
  • During photosynthesis, glucose is primarily produced by plants and most algae from water and carbon dioxide, using energy from sunlight, where it is used to create the most abundant carbohydrate cellulose in cell walls.
  • The chemical formula of glucose is C₆H₁₂O₆.
• Sucrose
  • It is crystallized white sugar produced by the sugar cane plant and can be found in households and foods worldwide.
  • The formulae for sucrose is C₁₂H₂₂O₁₁.
  • It is a disaccharide so when we hydrolyse it we will get one molecule of glucose and another molecule of fructose.
  • It is also known as table sugar.
  • The formulae for sucrose is C₁₂H₂₂O₁₁.

The pattern is:

31

31 × 2 + 1 = 63;

63 × 2 - 2 = 124;

124 × 2 + 3 = 251;

251 × 2 - 4 = 498

Hence, the answer is '498'.

The correct answer is option 2 i.e. Character, Field, Record, File, Database.

Additional Information

• A character is any letter, number, space, punctuation mark, or symbol that can be typed on a computer.
• The word "computer," for example, consists of eight characters.
• The term "fields" refers to columns or vertical categories of data.
• A record is composed of fields and contains all the data about one particular person,
• A file is the common storage unit in a computer, and all programs and data are "written" into a file and "read" from a file.
• A database is an organized collection of structured information, or data, typically stored electronically in a computer system.
• A database is usually controlled by a database management system (DBMS).

A mountain range is a group or chain of mountains that are near together and formed by orogenic forces.

Important Points

• The Aravalli Range (sometimes called Aravali) is a mountain range in Northern-Western India.
• It runs roughly 670 kilometers (430 miles) from Delhi to Gujarat, going through southern Haryana and Rajasthan.
• Guru Shikhar, at 1,722 meters, is the tallest summit (5,650 ft).
• The Aravalli Range, which dates back to the Proterozoic era, is considered the world's oldest fold mountain system.

Additional Information

• Vindhya and Satpura ranges run parallel to each other and separate peninsular India from the mainland. 
• The Himalayas protect the Indian subcontinent from the North East as a natural barrier providing geopolitical benefits to the country.
• Vindhya, Satpura, and Himalayas are all young-fold mountains.

Hence, Aravallis is the oldest folded mountain in India.
