Logic: Positional value of alphabet from left to right in each set are increasing by numbers alternatively, starts with 9 and following by 8.

So, "SCNR" should be placed in the place of "SDNR".

Hence, "SDNR" is the letter - cluster in the given series.

Logic:

• Number placed at second place is each set represents the positional value of alphabet placed at first place.
• Alphabets placed at third and fourth place has positional value in increasing order.

Hence, the missing term is "V22OP".

Logic: Positional value of alphabets in first set is decreasing by 1 in second set of alphabets.

Similar logic will be followed to find the third set of alphabets from fourth set of alphabets.

Hence, "GELCW" is the correct set of alphabets.

Here, all the options are unit of time except "Decibels".

Decibel is the unit of sound.

Hence, "decibel" is the odd word.

Logic: Positional value of alphabets are decreasing by consecutive number, starting from 5 and so on.

"STOCK" is coded as "NPLAJ",

Similarly, "PRICE" will be coded as;

Hence, the required code is "KNFAD"

Given: Aman is 12^th from the starting in a row and Raman is 24^th from the end. There are 25 boys between Aman and Raman.

Total Number of students in the row = Aman's position from start + Raman's position from end + 25 students between Aman and Raman.

⇒ 12 + 24 + 25 

⇒ 61

Hence, total number of the students in the row is "61".

Mistake PointsHere, in this question, you have not asked for minimum number of the students in the row. So, we have counted the maximum number of students in the given row.

Given: Five friends Aman, Chintu, Rahul, Gautam and Pintu are sitting in a row at different position.

• Aman is sitting at the left end while Pintu is sitting second from the right end.

• Only one friend sits between Pintu and Gautam. Which means Gautam will sit to the left of Pintu.

• Rahul is not an immediate neighbor of Aman and Gautam. That means Rahul will sit to the immediate right of Pintu and Chintu will sit at the place left in between Gautam and Pintu.

So, the final arrangement will be as;

Hence, "Chintu" is sitting in the middle of the row.

The least possible Venn diagram is;

Conclusion I: Some healthy are family → Does not follow

There is no direct relation between Families and healthy. So, this is indefinite conclusion and can not be considered as true conclusion.

Conclusion II: No healthy are family. → Does not follow

There is no direct relation between Families and healthy. So, this is indefinite conclusion and can not be considered as true conclusion.

but both the conclusions make complimentary pairs. So, Both conclusions follow either - or case.

Hence, the correct answer is "Either I or II follows".

Given:

Statement:

Some buses are cycle

Some cycle are car.

No car is scooter.

Least Venn diagram of the given statements is as follows;

Conclusion (I): Some car are buses. → False

There is no direct relation is given between car and buses. So, it is indefinite and can not be considered as true conclusion.

Conclusion (II): Some cars are cycle. → True

It is mentioned in the given statement that "some cycle are car". So, in the conclusion "some car are cycle" will be true.

So, only II conclusion follows here.

Hence, the correct answer is "Only II follows".

Given: 

Statement:

Some questions are answer.

All answers are wrong.

Some wrong are correct.

The least possible Venn diagram is as follows,

Conclusion (I): Some wrong are question. → True

As "some answer is question" and "all answer is wrong", then the above conclusion is considered to be true.

Conclusion (II):  Some correct are wrong. → True

It is mentioned in the statements that "some wrong are correct".

Conclusion (III): Some answer are wrong. → True

According to the statement, "all answer is wrong", then "some answer is wrong" will also be true.

Hence, the correct answer is "All follows".

Logic: First term is divided by 7 to get the second term.

21 ÷ 7 = 3 

So, similar logic will be followed in third term to get the fourth term.

574 ÷ 7 = 82

Hence, the correct answer is "82".

Given: 

Y = M < N < B = D; M > Z; N < J

Conclusion I: Z < J → True

On combining all three statements, we get;

Z < M < N < J 

Conclusion II: D > J 

On combining the first and third statements, we get;

J > N < B = D → False

So, in this arrangement, no definite relation can be found between D and J. 

Hence, the correct answer is "Only I follow".

The required logic is as follows;

Hence, the next term in the given series will be "100".

Given:

According to the above Venn diagram, G comes under the common part of Square, circle, rectangle and triangle but not pentagon.

It means G represents florist, money plant, roses and sunflower but not lily, as lily represents in pentagon.

Hence, the correct answer is "Florist who grow moneyplant, rose and sunflower but not lily".

Given: 

Triangle → chef

Circle → cafe

Pentagon → assistant chef

Rectangle → restaurant and

Square → hotel.

According to the above Venn diagram, "8" represents the common part of pentagon, triangle, square and rectangle but not circle.

So, it is representing the chef, assistant chef, restaurant and hotel but not cafe.

Hence, the correct answer is "Chef who run restaurant, hotel but not cafe with his assistant chef".

Logic: In the given series, Vertical and horizontal lines are added in vacant images inside the square from left to right.

In case of an Emergency in the country, President can suspend fundamental rights.

 Key Points

• Under Article 359 of the Indian Constitution, the President can suspend fundamental rights during an emergency.
• This means that the citizens of India would lose some of their basic rights, such as the right to freedom of speech, the right to assembly, and the right to move freely.
• The President can only suspend fundamental rights during a declared state of emergency, which can be either an internal emergency or an external emergency.
• There are a few fundamental rights that cannot be suspended even during an emergency.
• These are the rights to life and liberty (Article 21), the right against retrospective punishment (Article 20), and the right to equality (Article 14).
• The suspension of fundamental rights is a serious matter, and it is only done in the most extreme circumstances.
• The President must first declare a state of emergency, and then he or she must issue a notification suspending the fundamental rights.
• This notification must be placed before Parliament within two months of being issued.
• Parliament can then either approve or disapprove the notification.
• The suspension of fundamental rights is a controversial issue, and there have been many debates about whether it is ever justified.
• Some people argue that it is necessary in order to protect the country from threats, such as war or internal disorder.
• Others argue that it is a violation of human rights and should never be used.
• Ultimately, the decision of whether or not to suspend fundamental rights is a political one.
• The President must weigh the potential threats to the country against the potential harm to individual rights.
• In some cases, the President may decide that the suspension of fundamental rights is necessary to protect the country.
• However, it is important to remember that this is a drastic measure that should only be used as a last resort.

​Therefore the correct answer is President.

Calculations:

 27a3 – 8b3 + c3 = -18abc

Using the cube formula:

27a3 – 8b3 + c3 + 18abc = (3a)³ - 2b³ + c³ -3 × 3a × -2b × c

Comparing with x³ + y³ + z³ = 3xyz

x = 3a, y = -2b and z = c.

So, 3a + c = 2b.

Hence, the correct option is (4).

Calculations:

$\sqrt{324}× 65\div26+54=?$ = 18 × 65  /26 + 54 = 1170/26 + 54

⇒ 1170/26 + 54 = 1170/26 + 54 = 45 + 54 = 99

Hence, The Correct option is 4.

Calculations:

$√{\frac{(1)^2+(9)^2+18}{16}}=?$

$√{\frac{1+81+18}{16}}=?$

√(100)/(16) = √(25/4) = 5/2 = 2.5

Hence, The Correct Answer is option 2.

Concept use:

The H.C.F (Highest Common Factor) of two or more positive integers: The largest positive integer that divides the numbers without leaving a remainder. For example, take 8 and 12. The H.C.F. of 8 and 12 will be 4 because the highest number that can divide both 8 and 12 is 4.

Calculations:

Here, the smallest number among 34, 58 and 94 is 34.

Now, subtract 34 from each of the other numbers:

58 - 34 = 24

94 - 34 = 60

Now, We have to  find the HCF(Highest Common Factor) of 24 and 60.

Prime factorization of 24: 2³ × 3¹

Prime factorization of 60: 2² ×  3¹ × 5¹

The common factors are 2² and 3¹.

Therefore, the GCD of 24 and 60 is 2² ×  3¹ = 4 ×  3 = 12.

Hence, the largest number which divides 34, 58 and 94 leaving the same remainder in each case is 12.

Hence, The correct option is 3.

Calculations:

let no of children = x

Now

since 8 children  ate 7 chocolates each then 56 = (8 × 7) chocolates are already eaten →1

we are also given that the remaining students, ie (x-8) students each had one chocolate less than the average

Here

Average = Total no of chocolates/Total no of children

= 120/x

Therefore the remaining children ate

(x - 8) × ((120/x) - 1) chocolates in total → 2

From 1 and 2

56 + (x - 8) × ((120/x) - 1) = 120

=> (x - 8) × ((120/x) - 1) = 64

Upon simplifying we get the following quadratic

x² – 64x - 960=0

x = (64 + 16)/2 = 40

or

x = (64 – 16)/2 = 24

Hence the answer could be 40 or 24, but since the maximum number of children is being asked then the answer would be 40.

Given:

When P increased by 20% & Q decreased by 40%, their sum remained constant.

Calculation:

According to the question,

P + Q = 120% of P + 60% of Q

P + Q = 6/5 of P + 3/5 of Q

6P/5 - P = Q - 3Q/5 ⇒P/5 = 2Q/5

P = 2Q ⇒ P/Q = 2/1

Percentage by which P greater than Q is,

(2 - 1)/1 × 100 = 100% 

Hence, the correct answer is 100%.

Calculations:

Let the initial price of rice = Rs x/kg

15% decreased means x — x% of x = 85x/100.

According to Question

85/(85x/100) — 85/x = 1

Or, 100/x — 85/x = 1

Or, 15/x = 1

Or x = 15

One can buy 120/15 or 8 kg rice with the initial price.

 

Hence, The Correct option is 1.

Calculations:

The man sold the article for Rs. 840 at a profit of 20%,

Let's denote the cost price as CP. Since the selling price (SP) of Rs. 840 is 120% of the cost price (because of the 20% profit),

⇒ SP = 120/100 ×  CP

⇒ 840 = 1.2 ×  CP

⇒ CP = 840 / 1.2

⇒ CP = Rs. 700

The ratio of the marked price (MP) to the cost price is given as 10:7. Therefore, we can calculate the marked price as:

MP = 10/7 ×  CP

MP = 10/7 ×  700

MP = Rs. 1000

The discount given by the man is the difference between the marked price and the selling price, which is Rs. 1000 - Rs. 840 = Rs. 160.

Therefore, the discount percentage can be calculated as follows:

Discount Percentage = (Discount / Marked Price) × 100% = (160 / 1000) ×  100% = 16%

Hence, the correct option is 4.

Calculations:

Let Sale Price of one orange be Rs.x

The total sale price of 144 oranges = 144x

And Loss = 6x

So the Total Cost Price of 144 oranges = 150x

Thus loss% = (6x/150x) × 100 = 4% approx

 

Hence, The Correct Option is 3.

Calculations:

In Factory A, the ratio of male workers to female workers is 3 : 4.

In Factory B, the ratio of male workers to female workers is 5 : 4.

70% of female workers in Factory A got an increment, so 30% did not get an increment.

Since 12 females did not get the increment in Factory A,

⇒ 0.30F_A = 12, where F_A is the number of female workers in Factory A.  ⇒ F_A = 12 / 0.30 = 40.

85% of female workers in Factory B got an increment. Given that 68 females in Factory B got the increment

⇒ 0.85F_B = 68, where F_B is the number of female workers in Factory B.

⇒ F_B = 68 / 0.85 = 80.

The total number of workers in Factory A is (3 + 4) × (40 / 4) = 7 × 10 = 70.

The total number of workers in Factory B is (5 + 4) ×  (80 / 4) = 9 ×  20 = 180.

Therefore, the ratio of total workers in Factory A to total workers in Factory B is 70 : 180 = 7 : 18.

Hence, the correct option is 4.

Calculations:

First, let's determine the amount of sugar in the initial solution.

55% of 650 grams is 0.55 ×  650 = 357.5 grams. (Initial Amount of Sugar)

Let X be the amount of sugar we need to add to the solution to reach a concentration of 75%.

The new total amount of the solution will be 650 + X grams.

⇒ (357.5 + X) / (650 + X) = 0.75

⇒ 0.75 ×  (650 + X) = 357.5 + X

⇒ 487.5 + 0.75X = 357.5 + X

⇒ 487.5 - 357.5 = X - 0.75X ⇒ 130 = 0.25X

⇒ X = 130 / 0.25 ⇒ X = 520

Therefore, 520 grams of sugar should be added to the mixture so that sugar becomes 75 percent of the total mixture.

Hence, The correct option is 4.

Concept use:

When interest is compounded half-yearly, the rate of interest is divided by 2 and the time period is multiplied by 2.

Calculations:

 The principal amount (P) is Rs. 10,000, the rate of interest (r) is 6% per annum, and the time period (t) is 1 year

when it's compounded half-yearly, r becomes 6/2 = 3% per half-year, and t becomes 1 × 2 = 2 half-years.

The formula for compound interest (CI) is:

CI = P(1 + r/100)^t - P

Substituting the adjusted values for P, r, and t into the formula, we get:

CI = 10,000(1 + 3/100)² - 10,000

CI = 10,000(1.03)² - 10,000

CI = 10,000 × 1.0609 - 10,000

CI = 10,609 - 10,000

CI = Rs. 609

So, the compound interest on Rs. 10,000 in a year at 6 percent per annum if it is compounded half-yearly is Rs. 609.

The correct option is 2.

Calculations:

Let's denote the man's usual speed as S, and the distance he covers as D. 

If he walks at three-fourths of his usual speed, his speed becomes 3/4 × S, and the time he takes to cover the same distance becomes D/(3/4 × S) = 4D/(3S).

According to the Question, this slower time is 2 hours more than his usual time, so we have the equation:

⇒ 4D/(3S) = T + 2. = 4D/(3S) = D/S + 2.

⇒ 4D/(3S) - D/S = 2, ⇒ D/S (4/3 - 1) = 2, ⇒ D/S ×  1/3 = 2,

⇒ D/S = 2 ×  3, ⇒ D/S = 6.

Hence, the time taken by him to cover the distance with his usual speed is 6 hours.

Concept use :

Speed = Distance/ Time

Calculations:

Speed is the ratio of distance to time. If the distance covered increases by 60% and the time decreases by 35%, 

Let's assume the original distance is D and the original time is T.

So, the original speed is S = D/T.

Now, the distance is increased by 60% and the time is decreased by 35%.

So the new speed S' is (1.6D) / (0.65T).

Hence, the ratio of the original speed to the new speed S/S' is:

(D/T) / ((1.6D) / (0.65T)) = (D ×  0.65T) / (1.6D ×  T) = 0.65 / 1.6

⇒ 65/160 = 13 : 32

 

Hence, the ratio of the speed in the two cases is 13 ∶ 32.

Shortcut Trick

Total work = LCM(8, 12) = 24 units.

Efficiency of (A + B) = 3 units/day, and (B + C) = 2 units/day.

Total work done: 4A + 6B + 11C = 4(A + B) + 2(B + C) + 9C = 24

⇒ 4(3) + 2(2) + 9C = 24 ⇒ 16 + 9C = 24 ⇒ C = 8/9 units/day.

Time for C alone = 24 ÷ (8/9) = 27 days.

∴ The correct answer is 27 days.

Alternate Method

Given:

Time taken by (A + B) together = 8 days

Time taken by (B + C) together = 12 days

A worked for 4 days, B worked for 6 days, and C finishes the remaining work in 11 days.

Formula Used:

Total Work = LCM of given days

Efficiency = Total Work ÷ Time

Calculations:

Let the daily efficiency of A, B, and C be A, B, and C units respectively.

⇒ Total work done = 4A + 6B + 11C = 24

We can rewrite the equation by splitting the terms to match the known combined efficiencies:

⇒ 4A + 4B + 2B + 2C + 9C = 24

⇒ 4(A + B) + 2(B + C) + 9C = 24

Substitute the efficiencies of (A + B) and (B + C) from the table:

⇒ 4 × 3 + 2 × 2 + 9C = 24

⇒ 12 + 4 + 9C = 24

⇒ 16 + 9C = 24

⇒ 9C = 24 − 16

⇒ 9C = 8

⇒ C = 8/9 units/day

Now, calculate the total time C alone will take to complete the total work:

⇒ Time taken by C = Total Work ÷ Efficiency of C

⇒ Time taken by C = 24 ÷ (8/9)

⇒ Time taken by C = (24 × 9) ÷ 8

⇒ Time taken by C = 3 × 9 = 27 days

∴ The correct answer is 27 days.

Additional Information

Pipes & Cisterns

Conceptually identical to Time & Work. Inlet pipes have positive efficiency (filling work) while outlet pipes have negative efficiency (emptying work).

Work & Wages

Wages are strictly distributed in the ratio of the actual total work done by each individual, not merely based on their time spent or efficiency alone.

Alternate Days Work

Calculate the combined work done in one complete rotation cycle (e.g., 2 days for 2 people) and multiply by an integer to reach closest to the total work.

Concept use:

No of days × No of men = Total Work

Calculations:

If 56 men can complete a piece of work in 24 days,

the total amount of work is 56 men ×  24 days = 1344 man-days.

if 42 men can complete the same work, then total no of days 

So, 1344 man-days / 42 men = 32 days.

Hence, 42 men can complete the same work in 32 days.

Formula Used:

The area of a rhombus is given by the formula:

Area = 1/2 × d₁ × d₂

where d₁ and d₂ are the diagonals.

Concept Used:

In a rhombus, diagonals bisect at 90 degrees.

Calculation:

We know one of the diagonals d₁ = 44 cm and we do not know the other diagonal, d₂.

As in a rhombus, diagonals bisect at 90 degrees.

⇒ We can find d₂ using the Pythagoras theorem

Half the length of the given diagonal is 44/2 = 22 cm.

Given that a side of the rhombus is 24 cm,

By applying the Pythagoras theorem we get:

(24²) = (22²) + (d₂/2)²

⇒ 576 = 484 + (d₂/2)²

⇒ (d₂/2)² = 576 - 484 = 92

⇒ d₂/2 = √(92) = 2√23 

⇒ d₂ = 2 × 2√23 = 4√23, which is the length of the other diagonal.

Now, we can substitute d₁ and d₂ in the formula to calculate the area,

Area = 1/2 × 44 × 4√23

Area = 88√23 sq cm

∴ The area of the rhombus is 88√23 sq cm.

Concept use:

Volume of the Cylinder = π ×  r 2 × h

Calculations:

 Radius of the cylindrical vessel, r = 10.5 cm

Height of the cylindrical vessel, h = 10 cm

Volume of tea = 40% of the vessel's volume = 0.4 × π ×  r² × h

Volume of the vessel = π ×  r ² × h = π ×  (10.5 cm)² × 10 cm

Volume of tea = 0.4 ×  π ×  (10.5 cm) ² × 10 cm

Number of family members = Volume of tea / Volume of tea per member

Given that each family member drinks 49 cm³ of tea

Number of family members =  (0.4 ×  π ×  (10.5 cm) 2 × 10 cm) / (49 cm³)

The number of family members is approximately 28.

Hence, The Correct Answer is 28.

Given

The average speed of the following are as follows:

⇒ (P + Q) / 2 = 50

⇒ (R + Q) / 2 = 62.5

⇒ (R + S) / 2 = 55

⇒ (S + T) / 2 = 50

⇒ (P + T) / 2 = 47.5

Solution

Adding all the given average speeds we get :

⇒ 2(P + Q + R + S + T)/2 = 265

⇒ (P + Q + R + S + T) = 265 ...eq(1)

As given in the question,

⇒ (P + Q)  = 50 × 2 = 100

⇒ (R + S) = 55 × 2 = 110

⇒ P + Q + R + S = 210   ...eq(2)

Subtracting the eq (2) from eq(1),

⇒ (P + Q + R + S + T) - (P + Q + R + S) = 265 - 210 = 55

⇒ T = 55 km/hr

Calculation:

% Increase in population of the Countries in 2010 in India: (145 - 120)/120 × 100 = 20.83%

% Increase in population of the Countries in 2010 in USA = (80 - 65)/65 × 100 = 23.07%

% Increase in population of the Countries in 2010 in Shri Lanka = (51 - 40)/40 × 100 = 27.5%

% Increase in population of the Countries in 2010 in China = (152 - 130)/130 × 100 = 16.92%

% Increase in population of the Countries in 2010 in Japan = (61 - 50)/50 × 100 = 22%

% Increase in population of the Countries in 2010 in England = (83 - 70) × 100 = 18.57%

Hence, The Correct range of percentage is 16.92 percent - 27.5 percent.

Hence, The Correct option is 1.

The correct answer is 'The World Health Organisation's experts says that immunising'

 Key Points

• The issue in this sentence is subject-verb agreement. The subject, "The World Health Organization's experts," is plural.
• The correct verb form for the plural subject should be 'say', not 'says'. The verb 'says' is used for singular third-person subjects, such as 'he', 'she', or 'it'.
• Therefore, the sentence should be "The World Health Organization's experts say that immunising children against the coronavirus “is not a high priority” given the extremely limited global supply of vaccines."

Therefore, the correct answer is Option 1.

The correct answer is 'who has won a beautiful car'

 Key Points

• The problem in this sentence is the tense of the verb "has won".
• The use of "has won" suggests the action is in the recent past and still has relevance to the present.
• However, the sentence states "in the lottery yesterday", indicating that the event occurred in the past and is complete.
• The correct form should be "who won a beautiful car" to correctly represent the completed action.

Therefore, the correct answer is Option 2.

The correct answer is 'made of some kind'

 Key Points

• The underlined segment "make of some kinds of grain" is incorrect both in terms of verb form and countability.
• The verb should be "made" instead of "make" because "meals" is the object that has been made from grain.
• Additionally, "some kind" is grammatically correct because "grain" is an uncountable noun, so it should be referred to in the singular form, not plural ("kinds").

Therefore, the correct answer is Option 1.

The correct answer is 'No Improvement.'

 Key Points

• The bracketed part "As I did not think it was proper to" is grammatically correct.
• It correctly uses the past simple tense, indicating the speaker's previous judgment or consideration about what was proper.
• The other options provided are less formal or grammatically incorrect.

Therefore, the correct answer is Option 4.

The correct answer is 'will'

 Key Points

• In English grammar, "will" is used to express future actions decided at the moment of speaking or predicting future events.
• In this case, the sentence talks about a future action, specifically, ordering the army to open fire.

Therefore, the most appropriate option to fill in the blank is "will".

The completed sentence reads: "Rumours spread that he will soon order the army to open fire."

Additional Information

• Let's understand why the other options are not appropriate:
• "will be" - This option is inappropriate as it is used when referring to future actions that have already been planned or are certain to happen. This form often comes with a specific time reference. However, the sentence is about a speculative action (rumored), not a confirmed one, and there's no specific time reference.
• "would be" - This form is used for hypothetical or possible actions, usually in if-clauses or when reporting speech. Although there's an element of uncertainty in the sentence (rumours), the context doesn't fit the hypothetical nature that would require the use of "would be".
• "would have" - This form is used to describe unreal or hypothetical actions in the past. It often comes in if-clauses when expressing regrets, or missed opportunities. This sentence is not referring to a past hypothetical situation, so "would have" doesn't fit.

The correct answer is 'under, solve'

 Key Points

• The expression "going under the knife" is an idiomatic way to refer to undergoing surgery.
• "Solve" is used to mean addressing or remedying a problem, in this case, "his knee problems".

Therefore, the correct answer is Option 4.

The correct answer is 'regulations, is'

 Key Points

 

• "regulation, are" - The first part is incorrect because the use of "each" suggests that we are referring to individual elements of a group, thus making "regulation" plural as "regulations". The second part "are" is incorrect because "a larger plan" is singular and thus should take a singular verb "is".
• "regulations, is" - The first part "regulations" is correct because "each" refers to individual elements of a group, therefore making "regulation" plural. The second part "is" is correct because "a larger plan" is a singular noun phrase and requires a singular verb "is".
• "regulations, are" - The first part is correct as explained above. However, the second part "are" is incorrect because "a larger plan" is singular and requires a singular verb "is".
• "regulation, is" - The first part is incorrect because "each" refers to individual elements of a group, thus making "regulation" plural as "regulations". The second part is correct because "a larger plan" is singular and requires a singular verb "is".

Therefore, the most appropriate option to fill in the blanks is 2) "regulations, is".

The completed sentence reads: “It is clear that each of these draft regulations is part of a larger plan that is against the ethos and interests of the islands and islanders."

The correct answer is 'QPRS'

 Key Points

• Starting with Q establishes the main idea that fruits continue to respire.
• P and R add more details to this respiration process by explaining it involves taking in oxygen and giving off carbon dioxide.
• S brings in the comparison to human beings, which is then connected to S6's statement about breathing.

Therefore, the correct answer is Option 1.

The correct answer is 'Gracious'

 Key Points

• The word 'Benevolent' means well-meaning and kind. It is used to describe someone who is generous and has a disposition to do good.
• 'Gracious' is a synonym for 'benevolent' as it also describes someone who is courteous, kind, and pleasant, especially towards someone of lower social status.
• The other options 'Cruel', 'Barbaric', and 'Savage' are not synonyms for 'Benevolent', but rather, they are antonyms.

Therefore, the correct answer is Option 3.

The correct answer is 'Save'

 Key Points

• The word 'Squander' means to waste (something, especially money or time) in a reckless and foolish manner.
• 'Save' is an antonym for 'Squander' as it means to keep and store up (something, especially money) for future use.
• The other options 'Confine', 'Persecute', and 'Posit' do not carry meanings that are opposite to 'Squander'.

Therefore, the correct answer is Option 4.

The correct answer is 'Coureir'

 Key Points

• The correct spelling of this word is 'Courier'.
• 'Canine', 'Compile' and 'Bolster' are all spelled correctly.

Therefore, the correct answer is Option 4.

The correct answer is 'Tropical'

 Key Points

• 'Tropical' is spelled correctly and refers to regions or climates situated in or characteristic of the tropics.
• 'Tropikal', 'Trapical', and 'Tropicol' are incorrect spellings of 'Tropical'.

Therefore, the correct answer is Option 2.

The correct answer is 'Act without preparation'

 Key Points

• The idiom 'Play it by ear' originates from music, where it refers to playing music without reference to written notation.
• In a broader sense, it means to act according to the circumstances, rather than according to a predetermined plan.
• Example - Since I'm not sure when my last meeting will end, let's play it by ear for our dinner plans
• The other options do not correctly reflect this meaning.

Therefore, the correct answer is Option 3.

The correct answer is 'Lose the job'

 Key Points

• The idiom 'Get the axe' is often used to refer to someone losing their job.
• The 'axe' symbolizes a tool used to cut off something, in this case, employment.
• The other options do not correctly represent the meaning of the idiom.

Therefore, the correct answer is Option 1.

The correct answer is 'Anarchist'

 Key Points

• An 'Anarchist' is someone who believes in or tries to bring about anarchy, often seen as seeking to overturn organized government.
• 'Vandals', 'Criminal', and 'Amphibian' do not carry the same meaning as the given group of words.

Therefore, the correct answer is Option 2.

The correct answer is 'Battle of Assaye'

Key Points

• The passage clearly mentions, "as a newly appointed major-general, won a decisive victory over the Maratha Confederacy at the Battle of Assaye in 1803."
• The other options mentioned in the question do not align with the passage details about Wellesley's major-general rank and decisive victory.

Therefore, the correct answer is Option 2.

The correct answer is 'Waterloo'

Key Points

• The text states: "He ended the Napoleonic Wars when he defeated Napoleon at the Battle of Waterloo in 1815."
• The other options listed, 'Wellington', 'Dublin', and 'Tory', do not match the details provided in the passage about where Napoleon was defeated.

Therefore, the correct answer is Option 3.

The correct answer is 'Wellesley had never been a colonel'

Key Points

• The passage clearly states: "He was a colonel by 1796".
• The other statements are correct according to the passage.

Therefore, the correct answer is Option 4.

The correct answer is 'Commendable'

Key Points

• The term 'exemplary' in the passage is used to describe Wellington's battle record, meaning it is worthy of imitation; commendable.
• The other options 'Dishonorable', 'Disparaging', and 'Lacking' do not align with the meaning of 'exemplary'.

Therefore, the correct answer is Option 1.

The correct answer is 'Politics'

Key Points

• The passage states: "After the end of his active military career, he returned to politics."
• The other options 'Adaptive defensive style of warfare', 'Poetry', and 'Training ofyoung soldiers' do not match the details provided in the passage about Arthur Wellesley's career after the military.

Therefore, the correct answer is Option 2.
