In the passage, the authors tell that the Indian elementary education system is at poor condition compared to other communist countries despite the fact that it’s claimed India’s planning was socialist. They emphasise explicitly that the poor condition is because of our own mistakes rather than only “socialist planning”.

Option (A) is nowhere mentioned in passage and only comparison is made with socialist countries.

Option (B) is not the authors’ viewpoint as they criticise that Communist countries considered elementary education socialist commitment but not India.

Option (C) is not correct as though a comparison has been made, it’s not said that they are the best for elementary education.

Since Veeru killed Gabbar and a person cannot be killed by someone who is weaker than him, hence Statement 1 is correct.

Statement 2 cannot be inferred from the given information.

Drawing the diagram according to the given information:

Distance

Therefore, Pratik is 10 km from the starting point.

These statements are mentioned in the passage:

''The force also protects the lives and the properties of law-abiding men.'' So, option (A) is implied in the passage.

''But the bad citizen is only restrained from breaking these laws by fear of the consequence of his actions.'' So, option (C) is implied in the passage.

''And the necessary steps to compel the bad citizen to act as a good citizen are taken by this force. '' So, option (D) is implied in the passage.

• The passage discusses how the totalitarian regimes are fearful of civil society. It also discusses that by completely destroying civil society the regimes will in fact encourage more dissent. Thus they are also irrational in their approach. Therefore, Option (A) is correct.
• Option (B) is incorrect. Socialism is not discussed in the passage. Only Soviet ideology is discussed.
• Option (C) is also incorrect. This is because it can’t be concluded if the demerits of civil society first emerged in Russia or not.
• Option (D) is incorrect because it was Lenin’s belief that the destruction of civil society was crucial to totalitarian dictatorship. The passage however disagrees with this view.

The triangles are:

Triangle BMK, Triangle BMC, Triangle CMJ, Triangle CDJ, Triangle DEJ, Triangle MKJ, Triangle EJN, Triangle JIN, Triangle ENF, Triangle NFI, Triangle FIH, Triangle FGH, Triangle ABK, Triangle BCK, Triangle BCJ, Triangle KBJ, Triangle JCE, Triangle EFJ, Triangle IFJ, Triangle FEI, Triangle FGI, Triangle CKA, Triangle CKE, Triangle CEI, Triangle EGI, Triangle CJK, Triangle EJI.

Thus, there are 29 triangles.

Let the value of the memento be Rs. . 

Then, pay for seven week's work = Rs. .

Pay for one week's work Rs.

Pay for four week's work Rs.   ............(i)

Now, this is equivalent to Rs.    ............(ii)

Equating (i) and (ii), we get

Rs.

The letters A, B, D and E are on the adjacent faces of face C. 

Therefore, some other letters lie opposite ‘C’. 

The letters B, C and E are on the adjacent faces of face D. 

Therefore, A lies opposite D.

Let the scheduled appointment day be DD.

• Raju arrived on Friday and was two days early, so

  D=Friday+2  days=Sunday. D = Friday + 2days = Sunday

• If instead he had arrived on the following Wednesday (i.e.the Wednesday after that Friday), that Wednesday falls three days after Sunday.

• Therefore, he would have been 3 days late.

Let us note the following:

An implication is a conclusion that can be drawn from the passage although it is not explicitly stated.

The second option can be found directly mentioned in the passage.

It need not be implied.

The third option is implicit as the author says human activities make water eutrophic.

As per the author oligotrophic water is good for drinking as long as it is not turned eutrophic by human activities.

Thus, it is implicit that eutrophic water is not good for drinking.

Let us note the following:

An inference can always be logically deduced from the information given in the passage.

It is never directly stated in the passage.

The first and the second options find a direct mention in the passage.

So, these are not inferences.

The first and the second options have been used to prove the third option.

The author says that mere planting trees will not help.

The amount also needs to be huge.

Thus, the third option is the correct inference.

According to the passage:

• The entire passage talks about the increasing importance being given to data integrity. Therefore, the first option is the correct interpretation of the passage.
• The second, third, and fourth options are not the statements intended by the passage.
• Mining and product manufacturing has started realizing the value of data integrity.
• FINRA is trying to develop put data integrity to use.
• Cloud Storage Providers have long faced a challenge in the integrity of data.

Given:

0, 7, 26, 63, _

The given series follows the pattern

cube of the number subtracts one from it.

⇒ 1³ - 1 = 0

⇒ 2³ - 1 = 8 - 1 = 7

⇒ 3³ - 1 = 27 - 1 = 26

⇒ 4³ - 1 = 64 - 1 = 63

⇒ 5³ - 1 = 125 - 1 = 124

From the statement, it is definite that during the Covid-19 pandemic students are taking online classes for learning so it can be concluded from the statement that teachers are teaching them via online mode. Thus, a conclusion I follows.

The statement emphasises on the health issues of children due to spending more time on screen because of online classes but nothing is mentioned about the children who do not attend online classes. Thus, conclusion II doesn’t follow

According to the passage:

• The author is trying to say that photosynthesis takes place because of chlorophyll.
• Thus the author is trying to explain the importance of chlorophyll.
• The second option is not mentioned anywhere in the passage.
• The third and the fourth options explicitly mentioned in the passage.

The correct answer is 3 and 4 only.

Key Points

• Assumption 1 is not correct, the scenario of India doesn't come into picture in the given passage.
• Assumption 2 is not valid as horticulture crops not mentioned in the passage.
• Assumptions 3 and 4 are valid from the given passage,'...Pollination is an essential service that is the result of intricate relationships between plants and animals, and the reduction or loss of either affects the survival of both...'
• This implies a lack of natural vegetation is linked with the presence of pollinators. 

Given:

Red balls = 5

Blue balls = m

Concept used:

Probability = Number of favorable outcomes / Number of possible outcomes

Calculation:

Probability of getting red ball = 5/(5 + m)

Probability of getting blue ball = m/(5 + m)

According to the question,

⇒ 

⇒ m = 20

∴ The number of blue balls are 20.

According to the given information,

1) Shruti departs from her home and walks 26 m towards the east.

2) She then turns left and walks 18 m.

3) She turns right and walks 34 m.

4) She takes a right turn again and walks 30 m.

5) She then takes a left turn and walks 10 m.

6) She takes a final left turn and walks 12 m to stop at Point X.

Here, we can see that her home is 70 m in West direction from point X.

Hence, the correct answer is "70 m west".

Calculation:

Perimeter of second rectangle is 160 cm

⇒ 2( L2 + B2 ) = 160

⇒ ( L2 + B2) = 80cm ------ eq1

And one more relation of length and breadth is

⇒( L2 - B2 ) = 12 cm ------ eq 2

Add Eq 1 and eq 2 we get

⇒ 2L2 = 92 → L2 = 46 cm

⇒ B2 = 46 -12 = 34 cm

Then Ratio of L1 and L2 is 24 : 23

⇒ 23 unit = 46 cm

⇒ 24 unit = 48 cm

Ratio of breadth is 18 : 17

⇒ 17 unit = 34 cm

⇒ 18 unit = 36 cm

Then length of L1 is 48 cm and Breadth of B1 is 36

Area of rectangle is 48 × 36

⇒ 1728 sq cm

Hence 1728 sq cm is the correct answer.

The figure which replaces the question mark (?) to complete the figure:

Hence, the correct answer is "Option (2)".

The correct answer is 'Improper waste disposal from agriculture can destroy the aquatic ecosystem.'

Key Points

• According to the passage, improper management of agricultural waste and agricultural runoff into water bodies can lead to adverse effects on the aquatic ecosystem.
• Let us examine the given options.
• Option 1 states that appropriate legislation is important to protect the environment.
  • However, the legislative aspect to protect the environment is not the central focus of this passage.
  • Rather, the passage nearly touches upon legislation.
  • Thus, it is incorrect.
• Option 2 is incorrect because the passage mainly focuses on one aspect of modern agriculture, that is, increased use of nutrient fertilizers and their runoff into water bodies.
  • Modern agriculture is composed of several other practices as well that may not be harmful to the environment, such as sprinkler irrigation.
• Option 3 is correct as the passage centrally focuses on the phenomena of agricultural runoff and the adverse effect of eutrophication on the aquatic ecosystem.
• Option 4 is incorrect because even though the use of chemical fertilizers poses a negative influence on agriculture and water bodies, the focus of the passage is on the effect of agricultural runoff into water bodies.
  

Therefore, the correct option is 'Improper waste disposal from agriculture can destroy the aquatic ecosystem.'

The correct answer is 2 and 3

Key Points

• Let's look at each of the statements given:
  •  Structural and rural transformation is impossible when farms are mainly small and marginal
    • ​According to the first line of the passage, about 85 per cent of India's farms are small and marginal
    • According to the second line of the passage, India's story is of slow transformation (referring to China's fast structural and rural transformation)
    • Thus we can reasonably conclude that this is not a valid assumption
  • A good price incentive can trigger investments in agriculture
    • ​According to the sixth line of the passage, "...the relative price scenario changed significantly..."
    • According to the seventh line of the passage, "This boosted private investments in agriculture..."
    • Thus we can reasonably conclude that this is a valid assumption
  • India needs to build value chains for high-value agri-products like livestock and horticulture
    • ​If we carefully go through the passage, we can easily figure out that  'Compared to China and Vietnam, which have experienced fast structural and rural transformation, India's story is of slow transformation.'
    • Hence there is a need for building value chains for high-value agri-products like livestock and horticulture.
    • Hence it is a valid assumption. 
  • Higher global prices of agricultural commodities are essential for India's poverty reduction
    • This cannot be concluded from the given passage as higher global prices are not directly linked to India's poverty reduction. 

Thus the correct answer is 2 and 3. 

Calculations:

The three inlets P, Q and R fill (1/7)th of the cistern in 1 hour.

After 2 hours the cistern is filled (2/7)th and what remains is (5/7)remaining.

Inlet R is closed after 2 hours. The other two inlets P and Q fill (5/7)rd in 8 hours. Or P and Q fill (5/56)th in 1 hour.

So R alone fills (1/7)-(`5/56) = (8–5)/(56) = 3/56 of the cistern in 1 hour.

Or Inlet R, alone, takes 18 hours & 40 minutes to fill the cistern.

Given:

Two glasses of equal volume

One is half-filled with milk,

Other is 3/4^th filled with milk.

Calculation:

One is half-filled with milk = 1/2 of total capacity

Other is 3/4th filled with milk = 3/4 of total capacity

Let the total capacity of two vessels be LCM of 2 and 4,

⇒ LCM of 2 and 4 = 4

⇒ Total capacity = 4 liters

Now in the first glass,

⇒ Milk = 1/2 × 4 = 2 liters

Remaining is water = 4 – 2 = 2 liters

Now in the second glass,

⇒ Milk = 3/4 × 4 = 3 liter

Remaining is water = 4 – 3 = 1 liter

Their contents are then poured into another vessel.

⇒ Total milk in that container = 2 + 3 = 5 liters

⇒ Total water in that container = 2 + 1 = 3 liters

Ratio in container = Milk : Water = 5 : 3

∴ The ratio of milk to water in this vessel is 5 : 3.

Calculation:

According to given figure, we can say that

x axis shows the distance and y axis shows the time

Hence lower graph will show faster athlete and higher graph will show slower athlete

Height of A's is the lowest 

Hence, The race was won by A

Now, Height of B's graph is lower than A's graph up to 25 km

Hence, B was running faster than A up to 25 km 

The height of C's graph is lowest from the beginning

Hence, he run very fastly from the beginning 

∴ The correct statement is 1 and 2 only

After unfolding the given paper the figure formed is as shown below :

Hence, the correct answer is "Option 2".

Taking 1 and 2 common from the first two figure  and moving in either clockwise or anticlockwise direction we get:-

Pair of opposite number:-

5 is opposite to 3.

Now, in 2nd and 3rd we take take 2 as common and moving in either clockwise or anticlockwise direction we get :-

Pair of opposite number:-

5 is opposite to 3

4 is opposite to 1.

So, only 6 is left which is going to be opposite of 2.

Hence, the correct answer is 6.

The correct answer is '2 and 3 only'.

Key Points

• The given passage talks about the impact of melting glaciers on species diversity in the Antarctic region.
• Let's examine the given assumptions one by one.
• Assumption 1 states that regions of glaciers melt faster than other regions due to global warming. The correctness of this assumption cannot be determined because merely rising of temperature on the Western Antarctic Peninsula does not suggest that they were faster than other regions due to global warming; there might be other reasons as well that lead to faster warming of glaciers.
• Assumption 2 states that global warming can lead to seafloor segmentation in some areas. This assumption is correct because melting glaciers due to global warming lead to increased levels of suspended sediment in the water, as mentioned in the passage.
• Assumption 3 argues that melting glaciers can reduce marine biodiversity in some areas. This assumption is correct because as mentioned in the passage, melting glaciers cause a loss of species diversity in the coastal waters.

Thus, the correct answer will be 2 and 3 only.
