• The correct answer is option 2.
• persist means to continue to do something, hence, continuous form of verb will be used after it.
• In option 2) ' in doing' is given, which is correct and fits in the context of the given sentence.
• Hence, 2) will be the correct answer.

The correct answer is "have the talent to speak well".

Key Points

• "Gift of the gab" is an idiom that refers to the ability to speak easily and confidently in a way that makes people want to listen to you and believe you.
• It denotes the skill of being eloquent and persuasive in speech.
• For example, in a sentence, it can be used like this: "She's a saleswoman with the gift of the gab, capable of selling sand in a desert."
• Hence, the correct answer will be Option 3.

Additional Information

• Option 1: "Have the ability to adapt" is not related to the given idiom.
• Adaptability is about flexibility and the capacity to adjust oneself readily to different conditions, not specifically about speaking skills.
• Option 2: "Achieve sudden greatness" also doesn't align with the idiom.
• Achieving greatness involves success or distinction in a particular field or endeavor, not necessarily related to speaking.
• Option 4: "Receive a precious gift" is a literal interpretation of the idiom but does not reflect the actual figurative meaning of the phrase, which pertains to eloquent and persuasive speaking abilities.

• The correct answer is Option 1 i.e. 'Consize'.
• The correct spelling is 'concise' which means 'brief and precise'.
• Discern: To detect with senses, to perceive, recognize or comprehend with the mind.
• Particle: A very small piece of matter.
• Nurture: The act of nourishing or nursing.

• The correct answer is Option 1 i.e. Part CBAD.
• Among the given sentences the independent sentence is C So the answer begins with C.
• Second sentence is Part B which as continue the sentence which is C
• Sentence B & A make a pair. Sentence B talks about the fire engulfing the city which is continued by sentence A.
• Therefore, the correct sequence is followed by Option 1.

• The correct answer is Option 2 i.e. 'fastidious'.
• The meaning of the given words:

• Therefore, the best alternative is Option 2.

The correct answer is- 'frugal'

Key Points

The meaning of the given words: 

• Thrifty: A person who uses a minimum of something(especially money). (एक व्यक्ति जो कम से कम किसी चीज का उपयोग करता है (विशेषकर धन))
• Example: Trina learned thrift from her mother.
• Rigid: Rigorous and unbending, uncompromising.(कठोर और अडिग, समझौता न करने वाला)
• Grand: Of large size or extent; great in size; having higher rank or more dignity. (बड़े आकार या सीमा का; आकार में महान; उच्च पद या अधिक गरिमा होना)

• Discreet: Respectful of privacy or secrecy; quiet, diplomatic. (गोपनीयता या गोपनीयता का सम्मान; शांत, कूटनीतिक)

Therefore, 'frugal' is the synonym of  the word 'thrifty'.

• The correct answer is Option 1 i.e. 'incurred' which means 'to occur or to run into danger'.
• The meaning of the other words:
• Earned: To gain, to receive payment for work.
• Reaped: To cut the grain with a sickle; To gather a harvest by cutting.
• Raised: To cause to rise, to lift or elevate.
• Therefore, heavy losses can be occurred or incurred, all other options doesn't make any sense in the given blank.

• The correct answer is Option 4.
• The sentence is in simple present tense so the underlined phrase should be in simple present tense.
• 'we are going to have pleasure' is in future continuous tense so this cannot be the answer.
• 'we are having pleasure' is in present continuous tense and cannot be the answer.
• 'We will have a pleasure' is also wrong because it is in future tense.
• Option 4 'we have pleasure' is in simple present tense and is the most appropriate substitution to the underlined segment.

• The correct answer is Option 1 i.e. BADC.
• Sentence B explains about the DNA code. Sentence A which begins with 'this code' shows that it is the continuation of the DNA code. So these two sentences make the pair.
• Sentence D explains about the genetic material which is continued in the sentence C. So these two sentences make the pair.
• If we begin the sentence with D, it doesn't make a proper sequence after arrangement.
• Therefore, the correct sequence is BADC which gives a meaningful sentence after arrangement.

• The correct answer is Option 1.
• 'Darkness' is an abstract noun which can be spread everywhere. 'at everything' doesn't make any sense.
• Therefore, the correct sentence would be 'Darkness spilled like ink and began to spread everywhere.'
• case of parallelism is also followed as we can see spilled and began both are in 2nd form of verb as they are joined by conjunction "AND"

The correct answer is: Option 4.

Key Points

• The word "prosperity" means the state of being successful, especially in financial or material terms. (समृद्धि)
• Example: The country's prosperity is evident in its high standard of living and robust economy.
• "Adversity" refers to difficulties or misfortune, which is the opposite of prosperity. (विपत्ति)
• Example: She showed great resilience in the face of adversity.
• Hence, we can infer that the opposite of 'prosperity' is 'adversity'.

Therefore, the correct answer is: Option 4.

So, this will be the right choice.

The pattern followed here is:

Similarly,

Hence, the correct answer is WEPU.

The embedded figure is shown below.

Hence, the figure in option 2 is the correct answer.

Suppose the amounts with A, B and C are x, y and z respectively.

According to the given information,

A takes ₹6 from C, A will have equal amount as B.

→ x + 6 = y      ----(i)

A and B together have total ₹74.

x + y = 74      ----(ii)

Therefore,

x + y = 74

⇒ x + (x + 6) = 74

⇒ 2x + 6 = 74

⇒ 2x = 74 - 6

⇒ 2x = 68

⇒ x = 34.

Therefore, y = 34 + 6 = 40.

So, B has ₹40

Hence, the correct answer is 40.

When unfolded, the transparent sheet will look like the below figure:

Hence, the figure in option 2 is the correct answer.

Using the below table of symbols, we can create the family tree:

Given expression:  P + R ÷ S × M – K

After substitution, we get the following information: P is the husband of R. R is the mother of S. S is the sister of M. M is the brother of K.

The family tree is as shown below:

Hence, R is the mother of K.

In the given series, the circle alternately shifts by 1 triangle and 2 triangles in the anti-clockwise direction.

The bar symbols move in a clockwise direction. Alternately, there are 1 and 2 bar symbols in each step.

Therefore, the answer figure will have a circle in the triangle at the bottom and 1 bar symbol in the left triangle.

Only figure 2 satisfies this condition.

Hence, the correct answer is option 2.

The pattern followed here is:

(5, 7, 11) is a set of consecutive prime numbers.

In a similar way,

(23, 29, 31) is the only option which is a set of consecutive prime numbers.

Hence, the correct answer is (23, 29, 31).

Expression: 405 + 27 × 40 – 308 ÷ 22

After interchanging the signs:

1. ÷ and ×

405 + 27 ÷ 40 – 308 × 22

= 405 + 0.675 – 308 × 22

= 405 + 0.675 – 6776

= -6370.325 ≠ 314

2. • and ÷

405 ÷ 27 × 40 – 308 + 22

= 15 × 40 – 308 + 22

= 600 – 308 + 22

= 622 – 308

= 314

3. × and +

405 × 27 + 40 – 308 ÷ 22

= 405 × 27 + 40 – 14

= 10935 + 40 – 14

= 10975 – 14

= 10961 ≠ 314

4. • and –

405 – 27 × 40 + 308 ÷ 22

= 405 – 27 × 40 + 14

= 405 – 1080 + 14

Concept Used:

 $Triangles = n× {{n + 1} \over2}×H$

Where, 

n= number of small triangles

H = number of ‘end to end’ horizontal lines

 $Triangles = n× 2$Triangles=n×2Triangles=n×2

Where, 

n= number of small triangles

→ In, □ABCD: 16

n= number of small triangles = 8

$Triangles = 8× 2 = 16$Triangles=8×2=16Triangles=8×2=16Triangles=8×2=16

Hence, Total triangles in □ABCD = 16

→ In, ∆CEF: 6

n= number of small triangles = 2

H = number of ‘end to end’ horizontal lines = 2 (CF, HG)

$Triangles = 2× {{2 + 1} \over2}×2 = 6$

Hence, Total triangles in ∆CEF = 6

→Now, triangles formed due to joining shapes= 2(∆JIF, ∆AKF)

→ Now Adding all the ∆s:

Total ∆s = 16 + 6  + 2 = 24

Hence, the correct answer is 24.

The pattern followed here is:

The least possible Venn diagram is as follows:

Solution:

I. Some purses are coins. → False (it is possible but not definite)

II. No purse is coin. → False (it is possible but not definite)

III. No rupee is coin. → False (Some rupees are coins)

Thus, I and II form a complementary pair.

Hence, either conclusion I or conclusion II follows.

We know that in rhombus the diagonal intersects at right angle and equally divide diagonal

∴ In right angle ∆BOC

$BO; = ;\sqrt {{{\left( {20} \right)}^2} - {{\left( {12} \right)}^2}} ; = ;\sqrt {400 - 144} ; = ;\sqrt {256} ; = ;16,,cm$

∴ BD = BO + OD = 16 + 16 = 32 cm

Also AC = 24 cm (given)

Area of  rhombus = 1/2 × first diagonal × second diagonal = 1/2 × 32 × 24 = 384 cm²

We know that radius intersects chord perpendicularly and divides chord two equal parts

∴ AC = 5 cm

In ∆APC

$PC; = ;\sqrt {{7^2} - {5^2}} ; = ;\sqrt {49 - 25} ; = ;\sqrt {24} ; = ;2\sqrt 6 ;cm$

In ∆ACQ

$QC; = ;\sqrt {{9^2} - {5^2}} ; = ;\sqrt {81 - 25} ; = ;\sqrt {56} ; = ;2\sqrt {14} ;cm$

Distance between centers = PQ = 2 √6 + 2 √14 = 2 (√6 + √14) cm

Concept used:

Calculation:

3 × 2 ÷ 3 of 12 – 3 ÷ 2 × (2 – 3) × 2 + 3 ÷ 2 of 3

⇒ 3 × 2 ÷ 3 of 12 – 3 ÷ 2 × -1 × 2 + 3 ÷ 2 of 3

⇒ 3 × 2 ÷ 36 – 3 ÷ 2 × -1 × 2 + 3 ÷ 6

⇒ 3 × (2/36) – (3/2) × -1 × 2 + 3/6

⇒ 1/6 + 3 + 1/2

⇒ $3\frac{2}{3}$

Shortcut Trick

When the Cost Price (CP) of two articles is the same, the net profit or loss percentage is the arithmetic mean of the individual profit/loss percentages.

Net Profit/Loss % = (Percentage 1 + Percentage 2) ÷ 2

Net % = (−10% + 20%) ÷ 2 = 10% ÷ 2 = 5%

Since the result is positive, it is a profit.

∴ The correct answer is 5% profit.

Alternate Method

Given:

CP of Article 1 = ₹3050

CP of Article 2 = ₹3050

Loss on Article 1 = 10%

Profit on Article 2 = 20%

Formula Used:

Selling Price (SP) = CP × (100 ± Profit/Loss %) ÷ 100

Profit % = (Total SP − Total CP) ÷ Total CP × 100

Calculations:

⇒ Total CP = 3050 + 3050 = ₹6100

⇒ SP₁ = 3050 × (90 ÷ 100) = ₹2745

⇒ SP₂ = 3050 × (120 ÷ 100) = ₹3660

⇒ Total SP = 2745 + 3660 = ₹6405

⇒ Net Profit = 6405 − 6100 = ₹305

⇒ Net Profit % = (305 ÷ 6100) × 100

⇒ Net Profit % = 5%

∴ The correct answer is 5% profit.

Additional Information

Same Selling Price Case

If two articles are sold at the same Selling Price (SP), one at x% profit and another at x% loss, there is always a net loss of (x/10)² %.

Profit and Loss Basics

Profit % and Loss % are always calculated on the Cost Price (CP) unless stated otherwise in the question.

Successive Percentage Change

For two successive changes of a% and b%, the net effective change is given by [a + b + (a × b ÷ 100)]%.

Calculation:

100 × 70/100 × 130/100 × 130/100 = 118.3

Increase = 118.3 – 100 = 18.3

Percentage increase = (18.3/100) × 100 = 18.3 % = 18 % increase (approx.)

∴ The correct answer is 18%

Shortcut Trick

We know, 30% = 3/10

So, the increase % is = 183/1000 × 100 = 18.3% ~ 18%

Given

cos θ = 2p/(p² + 1) = base/hypotanuse

$\therefore ;perpendicular; = ;\sqrt {\left( {{p^2}; + ;1} \right)^2 - {{\left( {2p} \right)}^2}} {\rm{;}} = {\rm{;}}{p^2} - 1$

∴ cosec θ = hypotanuse/perpendicular = (p² + 1)/(p² – 1)

Two tangents drawn from external point on the circle are equal

∴ AP = AR = 11 cm

BP = BQ = 9 cm

And CQ = CR = 10cm

∴ Perimeter of triangle = 11 + 11 + 9 + 9 + 10 + 10 = 60 cm

Given:

2 sin²θ + 5 cos θ – 4 = 0

Concept used:

• sin2θ = (1 – cos2θ) 

Calculation:

2 sin2θ + 5 cos θ – 4 = 0

⇒ 2 (1 – cos²θ) + 5 cos θ – 4 = 0

⇒ 2 – 2 cos² θ + 5 cos θ – 4 = 0

⇒ 2 cos²θ – 5 cos θ + 2 = 0

⇒ 2 cos²θ – 4 cos θ – cos θ + 2 = 0

⇒ 2 cos θ (cos θ – 2) – 1 (cos θ – 2) = 0

⇒ (2 cos θ – 1) (cos θ – 2) = 0

⇒ cos θ = 1/2 or cos θ = 2 (not possible)

∴ cos θ = 1/2 = cos 60°

∴ θ = 60°

Now

cot θ + cosec θ = cot 60° + cosec 60° = (1/√3) + (2/√3) = 3/√3 = √3

∴ cot θ + cosec θ = √3

Shortcut Trick

If we put θ = 60° this satisfies the equation 2 sin2θ + 5 cos θ – 4 = 0

So, the value of

⇒ cot θ + cosec θ 

⇒ cot 60° + cosec 60°

⇒ (1/√3) + (2/√3)

⇒ √3

The given ratio of three numbers

1/2 : 2/3 : 3/4

⇒ 6 : 8 : 9

Let the numbers be 6x, 8x and 9x

According to question

Difference between the greatest and the smallest number = 27

⇒ 9x – 6x = 27

⇒ 3x = 27

⇒ x = 9

The first number = 6x = 6 × 9 = 54

The Second number = 8x = 8 × 9 = 72

The third number = 9x = 9 × 9 = 81

Sum of three numbers = 54 + 72 + 81 = 207

∴ Average = 207/3 = 69

We know that

(a − b)² = a² + b² − 2ab = 135 − 2 × 7 = 135 – 14 = 121

⇒ a – b = 11

∴ (a³ – b³) = (a – b) (a² + b² + ab) = 11 × (135 + 7) = 11 × 142 = 1562

9 years ago, The total age of 5 members = 33 × 5 = 165

Now total age of 8 members = 33 × 8 = 264

And total age of 5 members = 165 + 45 = 210

Total age of 3 new members = 264 – 210 = 54

Now let the age of new younger member = x

∴ age of middle member = x + 8

And age of eldest member = x + 16

According to question

x + x + 8 + x + 16 = 54

⇒ 3x + 24 = 54

⇒ 3x = 30

⇒ x = 10

∴ The age of eldest person = x + 16 = 10 + 16 = 26 year

12 cot²θ – 31 cosec θ + 32 = 0

⇒ 12(cosec²θ – 1) – 31 cosec θ + 32 = 0

⇒ 12 cosec²θ – 12 – 31 cosec θ + 32 = 0

⇒ 12 cosec²θ – 31 cosec θ + 20 = 0

⇒ 12 cosec²θ – 16 cosec θ – 15 cosec θ + 20 = 0

⇒ 4 cosec θ (3 cosec θ – 4) – 5 (3 cosec θ – 4) = 0

⇒ (4 cosec θ – 5) (3 cosec θ – 4) = 0

⇒ cosec θ = 5/4 or cosec θ = 4/3

∴ sin θ = 4/5 or sin θ = 3/4

⇒ 15 of 8 + 6 + 8

⇒ 15 × 8 + 6 + 8

⇒ 120 + 6 + 8 

⇒ 134

∴ The correct answer is 134

Concept used:

If BO & CO are the angle bisectors then ∠BOC = 90° + ∠A/2

Calculation:

If a number is divisible by 88 then it is must be divisible by 8 × 11

When a number is divisible by 8 then its last three digit is also divisible by 8

Calculation:

∴ 8y2 is divisible by 8 when y = 3

When a number is divisible by 11 then its difference of alternate sum of digit is equal to zero or 11.

Now,

In number 6220x55832

The difference between 6 + 2 + x + 5 + 3 and 2 + 0 + 5 + 8 + 2 must be zero or 11

The difference between (16 + x) and 17 will be zero or 11 when x = 1

∴ 5x + 5y = 5 × 1 + 5 × 3 = 5 + 15 = 20

Formula used:

Amount = Principal (1 + R/100)n

Calculation:

Let the principal and the amount be P and 1.191016P. 

⇒ 1.191016P = P(1 + R/100)³

⇒ 1.191016 = (1 + R/100)³

⇒ 1.06 = 1 + R/100

⇒ 0.06 = R/100

⇒ R = 6

∴ The rate is 6%

In ∆ ADE and ∆ ABC

∠A = ∠A (common)

∠ADE = ∠ABC (corresponding)

∴ ∆ADE ~ ∆ABC

∴ (AD/AB)² = ar ∆ADE/ar ∆ABC

⇒ ar ∆ADE/ar ∆ABC = (5/11)² = 25/121

Area of trapezium DEBC = Area of ∆ABC – Area of ∆ADE = 121 – 25 = 96

∴ Area of ∆ABC : Area of trapezium DEBC = 121 : 96

Given:

A can do the work = 5 days

B can do the work = 20 days

C can do the work = 60 days

Calculation:

One-day work of A = 1/5 days      ----(1)

One-day work of B = 1/20 days      ----(2)

One-day work of C = 1/60 days      ----(3)

Adding equations (1), (2) and (3), we get

One-day work of (A + B + C) = {(1/5) + (1/20) + (1/60)}

⇒ (A + B + C) = {(12 + 3 + 1)/60}

⇒ (A + B + C) = 16/60 = 15/4 

One-day work of (A + B + C) = 15/4 days 

$\therefore ;{\rm{work;done;by;them;together}}; = ;\frac{{60}}{{16}}; = ;\frac{{15}}{4}; = ;3\frac{3}{4};days$

x⁴ + x^-4 = 1442

⇒ x⁴ + 1/x⁴ = 1442

Adding 2 both sides

x⁴ + 1/x⁴ + 2 = 1442 + 2 = 1444

⇒ (x² + 1/x²)² = (38)²

⇒ x² + 1/x² = 38

Again adding 2 both sides

x² + 1/x² + 2 = 38 + 2 = 40

⇒ (x + 1/x)² = 40

⇒ x + 1/x = $\sqrt{40}$

∴ x + x^-1 = $2\sqrt {10}$

Given:

There was 25% discount and the lady got 20% further discount.

Calculation:

Let the price tag on the bag was Rs. P

Now,

P × (75/100) × (80/100) = 480

⇒ P × 3/4 × 4/5 = 480

⇒ P = 800

∴ Price tag on the bag was Rs. 800

Shortcut Trick

We know, 25% = 1/4 and 20% = 1/5

According to the question,

⇒ 12 unit → 480

Then, 20 unit → 480/12 × 20 = Rs.800

Total imports in 2013-2014 = 824

Total imports in 2014-2015 = 1014

Increase = 1014 – 824 = 190

Percentage increase = (190/824) × 100 = 23.05%

Total imports in 2014-2015 = 1014

Total imports in 2015-2016 = 1137

Increase = 1137 – 1014 = 123

Percentage increase = (123/1014) × 100 = 12.13%

Total imports in 2015-2016 = 1137

Total imports in 2016-2017 = 1513

Increase = 1513 – 1137 = 376

Percentage increase = (376/1137) × 100 = 33.06%

Total imports in 2016-2017 = 1513

Total imports in 2017-2018 = 1658

Increase = 1658 – 1513 = 145

Percentage increase = (145/1513) × 100 = 9.58%

∴ the percentage increase in Imports is the highest in comparison to its previous financial year = 2016-2017

Total of exports and imports in 2014-2015 = 1256 + 1014 = 2270

Total of exports and imports in 2015-2016 = 1661 + 1137 = 2798

Total of exports and imports in 2016-2017 = 1538 + 1513 = 3051

Total of exports and imports in 2017-2018 = 1305 + 1658 = 2963

∴ Total of exports and imports is the highest in the year = 2016-2017

Total export during the five financial years = 638 + 1256 + 1661 + 1538 + 1305 = 6398

∴ Average = 6398/5 = 1279.6

Total imports during the five financial years = 824 + 1014 + 1137 + 1513 + 1658 = 6146

Total exports during the five financial years = 638 + 1256 + 1661 + 1538 + 1305 = 6398

Required ratio = 6146 : 6398 = 3073 : 3199
