Given: Neptune, Planet, Moon

The logic followed here is: Neptune is a Planet, but Moon is not. Moon is a natural satellite.

Hence, option (4)  is the correct answer.

Given:

Efficiency of Amit = 2 × Efficiency of Ramit

Concept used:

Total work = Efficiency × Time period

Calculation:

The efficiency of Amit = 2

Efficiency of Ramit = 1

Total work = (2 + 1) × 28 = 3 × 28 = 84

Number of days Ramit takes to complete the whole work = 84/1 = 84

∴ The number of days in Ramit will complete the work is 84 days.

GIVEN:

The average of 40 numbers = 25

CONCEPT:

Basic Average concept.

FORMULA USED:

Average = Sum of all numbers/Total numbers

CALCULATION:

Sum of numbers = 40 × 25 = 1000

23, 25 and 41 are mistakenly written as 32, 52 and 15 respectively.

⇒ Change in sum = (23 + 25 + 41) – (32 + 52 + 15)

= 89 – 99

= -10

Actual sum of numbers will be 10 less.

⇒ Sum of numbers = 1000 – 10 = 990

∴ Correct average = 990/40 = 24.75

The logic followed is:

middle number = sum of the bottom number - top number

In fig 1:

10 = (7 + 9) - 6

10 = 16 - 6

10 = 10

In fig 2:

10 = (5 + 8) - 3

10 = 13 - 3

10 = 10

Similarly,

? = (9 + 6) - 4

? = 15 - 4

? = 11 

Hence, the correct answer is "11".

Given

Ratio of principal and amount is 4 : 5 at a certain time. If it becomes 5 : 7 after 3 years

Concept used

Rate = (interest × 100)/(Principal × time)

Calculation

Principal : Amount = 4 : 5

Principal be equal 

Multiply the first ratio with 25 and second with 20

⇒ (4 : 5) × 25 

⇒ (5 : 7) × 20

Principal : Amount = 100 : 125

Principal : Amount = 100 : 140

Difference in amount = 140 - 125

Difference in Amount = 15

3 year = 15

1 year = 5

Rate = (interest × 100) / Principal × time

Rate = 

Rate = 5%

∴ The required simple rate of interest is 5%.

The logic follows here : 
1. Sukhoi Su-30MKI is a Fighter Jet.
2. INS Vikrant is different from these two, it is an Aircraft Carrier.

Given:

x + 1/x = 25

Concept Used:  

If x + 1/x = p then, x – 1/x = √(p² – 4)

Calculation:

It is given that x + 1/x = 25

 We know that if x + 1/x = p then, x – 1/x = √(p² – 4)

⇒ x – 1/x = √(25² – 4)

⇒ x – 1/x = √(625 – 4)

⇒ x – 1/x = √621

‘Knife’ is related to ‘Cut’, means we use knife for cutting.

Similarly,

We use pen for writing.

Hence, Write is the correct answer.

As Silence is opposite to noise, similarly Baldness is opposite to Hair.

From Statement I:

From this statement, we get the following ranking.

Person in the row = 8 persons + Akansha + 4 persons + Rhea + 7 persons + Harshita + 8 persons

So, we get that Rhea is 17th from the bottom in the class.

Clearly, Statement I alone is sufficient to answer the question.

From Statement II:

From this statement, we get the following ranking.

Person in the row = 11 persons + Yamini + 13 persons + Rhea + 4 persons

So, we get that Rhea is 5th from the bottom in the class.

Clearly, Statement II alone is sufficient to answer the question.

Clearly, Either Statement I or Statement II alone is sufficient to answer the question.

Hence, option C is the correct answer.

Option 2 illustrates the law of conservation of mass.

The law of conservation of mass states that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products. This means that matter is neither created nor destroyed in a chemical reaction.

In option 2, 12 g of CO reacts with 32 g of O2 to form 44 g of CO2. The total mass of the reactants (12 g + 32 g = 44 g) is equal to the total mass of the product (44 g). This illustrates the law of conservation of mass.

Option 1 is an example of the law of definite proportions, which states that a given compound always contains the same elements in the same proportion by mass.

Option 3 is not a valid example of the law of conservation of mass, as heating carbon in a vacuum can lead to the release of gases such as carbon dioxide, carbon monoxide, and carbon suboxide, which can escape and change the mass of the system.

Option 4 is an example of a physical change, where the state of matter of a substance changes, but the mass of the substance remains the same. It does not illustrate the law of conservation of mass.

The atomic number of Helium is Z = 2. The electronic configuration is, 2. Therefore, Helium is a noble gas with two valence electrons.

Sir James Chadwick, 20 October 1891 – 24 July 1974 was a British physicist who was awarded the 1935 Nobel Prize in Physics for his discovery of the neutron in 1932.

The acceleration due to gravity on earth is given by g = GM/R²

From the above equation, we observe that acceleration is directly proportional to the mass of the earth. So, if the mass of the earth is increased by 25 % and R is kept constant, the value of g will also increase by 25%.

Let the numerator = x and denominator = y

y + 3 = 2y ⇒ y = 3

x +1= 3 ⇒ x = 2

∴ xy = 2 × 3 = 6

The correct answer is the Quasi-Judicial Procedure.

Important Points

• The procedure of Impeachment of the President of India is the Quasi-Judicial Procedure.

  • In the case of the Lok Sabha, this means that the motion must be signed by at least one-fourth of the total Lok Sabha members.
  • A 14-day notice is given to the President of India.
  • Then, Lok Sabha passes the impeachment charges with a two-thirds majority and sends it to Rajya Sabha.
  • Then, the Rajya Sabha investigates the charges.
  • While Rajya Sabha is investigating the charges, the President has the right to sit in the proceedings.
  • Rajya Sabha agrees to the charges and passes it with a two-thirds majority and the President is removed.

The correct answer is the Election Commission of India.
