Question Discussion & Solution

When the box will be constructed, the following symbols will be opposite to each other as shown below:

So, when the box will be constructed, the symbols O and K will be opposite to each other.

Hence, option 3) O and K is the correct answer.

Given equation: 49 A 7 B 5 C 6 = ?

After interchanging alphabets: 49 ÷ 7 + 5 × 6 = ?

7 + 30

37

Hence, ‘37’ is the answer.

The correct answer is 2, 3, 4, 1.

• Chauhan Dynasty as per the chronological order:
  • Ajayraj - (1110 - 1135 AD).
  • Arnoraj - (1135 - 1150 AD).
  • Vigraharaj IV - (1150 - 1164 AD).
  • Prithviraj III - (1178 - 1192 AD).

Key Points

• According to the Raj Shekhar Prabandh Kosh, the Chauhan dynasty was established by Vasu Dev Chauhan in 551 AD.
  • Their initial capital was Ahichhitarpur.
  • After Vasudev Chauhan comes Samant Raj as his successor.
  • Durlabh raj was the first Chauhan emperor when the Muslims invaded Ajmer.

Additional Information 

• The Chauhan Dynasty:
  • The word Chauhan is the vernacular form of the Sanskrit term Chahamana.
  • While the earlier versions of Chandbardai's work Prithviraj Raso do not mention Chauhan as born from Agnikunda, the later versions do.
  • The 15th-century Hammira Mahakavya of Nayachandra Suri & Jayanayak's Prithviraj Vijay considers Chauhans as Suryavanshi. 
  • Based on Bijloia Inscription, Dr. Dasrath Sharma considers that the early ancestor of Chauhan was born at Ahichchhatrapura in the gotra of sage Vatsa. Ahichchhatrapura can be identified with modern Nagaur.
  • Chahamanas probably started out as petty rulers of Ahichchhatrapura. As the Chahamana territory expanded, the entire region ruled by them came to be known as Sapadalaksha.
• Major Chauhan dynasties include:
  • Chauhans of Shakambhari.
  • Chauhans of Ranthambore.
  • Chauhans of Jalore.

Concept:

• Newton's Second Law of motion states that the rate of change of momentum of an object is proportional to the applied force in the direction of the force.
•  \(F = \frac{{dp}}{{dt}} = \frac{d}{{dt}}\left( {mv} \right)\;\left( \because {p = mv} \right)\) 

i.e., Force = ma ⇒ Force (F) ∝ a

Where,

F = the force applied, m = the mass of the body, a = the acceleration produced. p = linear momentum, v = velocity of particle at some instance

Explanation:

Given that;

Mass = 100 kg

Acceleration (a) = 10 m/s2

External force on body (F) = ma = 100 × 10 = 1000 N

Concept:

Classes in java are the collection of objects which has some similar properties. A class in java contains fields, methods, constructors, blocks, interfaces.

Explanation:

Everything is associated with classes and objects. An object is an instance of the class which has some state and behavior.

An object class(java.lang.object) is the parent class of all the java classes.  It can be used when we do not know about the type of the object. By having the object as the super class , without knowing the type we can pass around objects using the object declaration.
