Question Discussion & Solution

CONCEPT:

Nuclear reactor:

• It is a device in which a nuclear reaction is initiated, maintained, and controlled.
• It works on the principle of controlled chain reaction and provides energy at a constant rate.

EXPLANATION:

• Uranium is used as a fuel in a nuclear reactor.
• The Process is illustrated by the diagram, where the mass difference between the reactants (Uranium) and the products (Krypton and Barium) is converted into energy.

Encapsulation

• It is the process or method to contain the information.
• Wrapping of data and function into a single unit is called data encapsulation
• Encapsulation is a method to hide the data in a single entity or unit along with a method to protect information from outside.
• It can be implemented using by access modifier.  

Important Point:

• Data Abstraction is the method of hiding unwanted information.
• Polymorphism is a feature of OOPs that allows the object to behave differently in different conditions. 
• The objects that help to perform abstraction are encapsulated but the objects that result in encapsulation need not be abstracted.

According to the given information-

Anklets, Tube and Chair are not related to each other in any manner. 

Hence, option 3) is the correct answer.

The correct answer is 100.

• 100 per cent share of the Central Government in the 'Sambhar wetland project' under the Twelfth Five Year Plan (2012 - 2017).

Additional Information 

• The objectives of the Twelfth Five-Year Plan were:
  • To create 50 million new work opportunities in the non-farm sector.
  • To remove gender and social gap in school enrolment.
  • To enhance access to higher education.
  • To reduce malnutrition among children aged 0–3 years.
  • To provide electricity to all villages.
  • To ensure that 50% of the rural population has access to proper drinking water.
  • To increase green cover by 1 million hectares every year.
  • To provide access to banking services to 90% of households.

The Logic here is as follows:

(1^st Number × 2^nd number) × 4 = 3^rd Number

In (6, 8, 192)

(1^st Number × 2^nd number) × 4

= (6 × 8) × 4

= 48 × 4

= 192 = 3^rd Number

Now check the all options,

Option (1) (12, 13, 263)

(1^st Number × 2^nd number) × 4

= (12 × 13) × 4

= 156 × 4

= 624 ≠ 3^rd Number

Option (2) (8, 11, 180)

(1^st Number × 2^nd number) × 4

= (8 × 11) × 4

= 88 × 4

= 352 ≠ 3^rd Number

Option (3) (11, 9, 396)

(1^st Number × 2^nd number) × 4

= (11× 9) × 4

= 99 × 4

= 396 = 3^rd Number

Option (4) (7, 5, 78)

(1^st Number × 2^nd number) × 4

= (7 × 5) × 4

= 35 × 4

= 140 ≠ 3^rd Number

Hence, the correct answer is "(11, 9, 396)".
