Question Discussion & Solution

Let the three consecutive numbers be x, x + 1, x + 2

⇒ x + (x + 1) + (x + 2) = 345

⇒ 3x + 3 = 345

⇒ 3x = 345 – 3 = 342

\(\Rightarrow x = \frac{{342}}{3} = 114\)

So the three consecutive numbers are 114, 115 and 116. And the middle number is 115.

The correct answer is Udaipur.

The correct answer is Chittorgarh.

Key Points

• Bojunda Stromatolite Fossil Park is situated in Chittorgarh
• The Bojunda Stromatolite Fossil Park was in the news in May 2021 because the Department of Mines and Geology, in collaboration with the Chittorgarh district administration, proposed the creation of a 12-hectare geopark at this location.
• The original park was roughly 3.5 hectares in size, but it has now been reduced to 0.5 hectares.

Additional Information

• About Stromatolite
  • Stromatolites are layered bio-chemical mounds, column or sheet-like sedimentary rocks created in shallow water by biofilms of microorganisms capturing, binding, and cementing sedimentary grains.
  • Stromatolites are fascinating windows into the origins and evolution of life on our planet.​

Inheritance

The capability of a class to derive properties from another class is called Inheritance

• The class that inherits properties from another class is called Subclass or Derived Class.
• The class whose properties are inherited by a subclass is called Base Class or Superclass.

Syntax for Inheritance

class derived_name : access_mode base_class

{

//body of derived class

};

Additional Information 

Polymorphism

Polymorphism is mainly divided into two types:

• Compile-time Polymorphism
• Runtime Polymorphism

Compile-time polymorphism

This is achieved by function overloading or operator overloading.

• Function Overloading - When there are multiple functions with the same name but different parameters then these functions are said to be overloaded
• Operator overloading - When there are multiple operations can be performed by using single operator is called operator overloading for example operator ‘+’ when placed between integer operands, adds them and when placed between string operands, concatenates them

Run Time Polymorphism

It is achieved by Function Overriding.

Conclusion

Feature of Reusability is followed by inheritance so the correct answer is the inheritance.
