Question Discussion & Solution

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.

The least possible Venn diagram is,

Conclusion 1: All apples are bananas → True (This is definitely true)

Conclusion 2: Some bananas are mangoes → True (This is definitely true)

Hence, both 1 and 2 follow.

The correct answer is 30 October 1974.

• Rajasthan State Mines & Minerals Ltd. was established on 30 October 1974.

Key Points

• The prime objective of RSMML is to achieve cost-effective technological innovations in the mining of minerals and to diversify into mineral-based downstream projects
• The major activities of the company have been divided into four parts called Strategic Business Units & Profit Centres (SBU & PC) under the direct control of the corporate office situated at Udaipur. 
• The four SBU & PC are as follow
  • SBU & PC Rock phosphate, Udaipur
  • SBU & PC Gypsum, Bikaner
  • SBU & PC Limestone, Jodhpur
  • SBU & PC Lignite, Jaipur

India has three distinct crop seasons in the northern and interior parts of the country, namely Kharif, Rabi, and Zaid.

Important Points

Lets' look at the cropping season of India:

• The Kharif season (June-September) largely coincides with Southwest Monsoon under which the cultivation of tropical crops are possible.
  • Major Crops- Rice, Cotton, Jute, Jowar, Bajra, and Tur.
• The Rabi season (October-March) has low-temperature conditions which help in the cultivation of temperate and subtropical crops.
  • Major Crops- Wheat, Gram, and Mustard.
• The Zaid season (April-June) is a short duration summer cropping season beginning after harvesting Rabi crops.
  • Major Crops- Watermelons, Cucumbers, Vegetables, and Fodder Crops.

From the above, we can conclude that Wheat is not a Kharif crop as it is grown in the Rabi season.

Explanation:

• The metallic property of the elements of the periodic table decreases when we move across the group whereas it increases when we go down the group, as we go down the number of electrons increases and thereby their distance from the nucleus increases. 
• This increase causes them to shed more electrons and thereby have a greater electropositive or metallic character. 

Among the given compounds Na shows maximum Metallic character.
