The correct answer is 3

Key Points

• 'the Atlantic ocean' should be there in place of 'Atlantic ocean'
• Definite article before the names of bodies of water.
  

Example: the Amazon, the Ganges, the (English) Channel, the Panama Canal, etc.

​Thus, the correct sentence is: The first and decisive step in the expansion of Europe overseas was the conquest of the Atlantic ocean.

Additional Information

• The definite article is used with geographical names:
• Names of countries which are collective, plural or modified by an adjective or an of-construction take the definite article the: the Czech Republic, the Netherlands, the People's Republic of China, the Philippines, the United Kingdom (UK), the United States of America (USA), etc.

The correct answer is: 1.

Key Points

• The context of the sentence tells us that the French phrase la danse macabre, which describes the allegorical picture of death's universal power, gave the word "macabre" its importance.
• In Active voice, 'been' doesn't fit in grammatically after the be verb 'had'. (as in part 1 of the sentence).
• Also, 'had been' is is used when something began in the past, went on for some time and then ended. But in this case, macabre still has its significance as it hasn't ended yet.
• Thus, 'had been' must be replaced by 'has' in part (1) of the sentence.

Therefore, the correct sentence is: The word ‘Macabre’ has gained its significance from its use in French as la danse macabre for the allegorical representation of the universal power of death.

The correct answer is was feeling

Key Points

• The subject and the verb should agree with each other in the given sentence i.e. If the subject is singular, the verb used should be singular.

Calculation:

Here we use elimination method for finding the square root of 1485961

The unit digit of no. 1485961 is 1

We have 4 options 1213, 1219, 1229 and 1239

We get unit digit 1 when we square a no. that ends with 1 or 9. So, option (1) 1213 is eliminated.

Now we take the square of 1220 that is > 1219 and < 1229

⇒ (1220)² = 1488400

This value 1488400 > 1485961, so we can say that 1485961 is the square of 1219.

Given:

a² + b² = 80 and ab = 32

Formula used:

(a + b)2 = a2 + b2 + 2ab

(a – b)2 = a2 + b2 – 2ab 

Calculation:

(a + b)² = a² + b² + 2ab = 80 + 2 × 32 = 80 + 64 = 144

⇒ a + b = 12

(a – b)² = a² + b² – 2ab = 80 – 2 × 32 = 80 – 64 = 16

⇒ a – b = 4

$\frac{{a - b}}{{a + b}} = \frac{4}{{12}} = \frac{1}{3} = 0.333~$

Shortcut TrickLet a = 4 and b = 8, then a² = 4² = 16 and b² = 64

then a2 + b2 = 16 + 64 = 80 satisfied

So, $\frac{{a - b}}{{a + b}} = \frac{4}{{12}} = \frac{1}{3} = 0.333~$

Calculation:

${\left( { 7776} \right)^{\frac{2}{5}}} = {\left[ {\left( { {2^5}) \times ( {3^5}} \right)} \right]^{\frac{2}{5}}}~~$

$\Rightarrow {\left( { 2} \right)^{5 \times \frac{2}{5}}} \times {\left( { 3} \right)^{5; \times ;\frac{2}{5}}}$

$\Rightarrow {\left( { 2} \right)^{2;}} \times {\left( { 3} \right)^{2;}} = 4 \times 9 = 36$

Shortcut Trick$8x - \frac{8}{x} - 16 = 0$

$\Rightarrow 8x - \frac{8}{x} = 16$

$\Rightarrow 8\left( {x - \frac{1}{x}} \right) = 16$

$\Rightarrow x - \frac{1}{x} = 2$

If$;x - \frac{1}{x}; = k$ then the value of ${x^3} - \frac{1}{{{x^3}}} = k\left( {{k^2} + 3} \right)$ and here k = 2

$\Rightarrow {x^3} - \frac{1}{{{x^3}}} = 2\left( {{2^2} + 3} \right) = 14$

$\Rightarrow {x^3} - \frac{1}{{{x^3}}} + 8 = 14 + 8 = 22$

The triangle in which the orthocenter, circumcentre, Incenter and the centroid coincide each other at a point is known as Equilateral triangle

Given:

Percentage decrease in radius of circle = 25%

Formula used:

Area of circle = πr²

where r → radius of the circle

Calculation:

The radius of the circle is r.

If the radius of a circle is decreased by 25%

New radius = r - r × 0.25 = 0.75r

Old Area = πr²

New Area = π × (0.75r)² = π × 0.5625r² = 0.5625πr²

percentage decrease in the area of the circle = $\frac{πr^2-0.5625πr^2}{πr^2}× 100=43.75$%

∴ Area of the circle is decreased by 43.75%

Shortcut TrickPercentage decrease = 25 + 25 - (25 × 25/100) = 43.75%

Given:

Decrease in the price of a fan = 40%

As Price =  40% = 2/5 and Sale =  50% = 1/2

So, Decrease in revenue = 1/10 × 100 = 10% 

Shortcut TrickNet percentage increase/decrease in revenue = ± x ± y ± xy/100

Net percentage increase/decrease in revenue 

⇒ - 40 + 50 – (40 × 50)/100 = - 40 + 50 – 20 = -10%

∴ 10% decrease in fan’s revenue.

Given:

Total sum = Rs. 2489

Diminution in shares of A, B and C = Rs. 12, Rs. 12 and Rs. 5

Ratio of their share = 5 : 3 : 4

Calculation:

Let ratio of A, B and C be 5x, 3x and 4x

Total Sum = Rs. 2489

New sum after diminishing the amount

⇒ 2489 – 12 – 12 – 5

⇒ 2489 – 29 = 2460

∴ C’s share = (4x/12x) × 2460 = 820

Given:

The milk and water in two vessels are in the ratio of 3 : 1 and 7 : 11 respectively.

Concept used:

Rule of Alligation

Calculation:

Ratio of milk and water in Vessel 1 = 3 : 1

Ratio of milk and water in Vessel 2 = 7 : 11

Now using alligation method for milk,

∴ required ratio = (7 – 9)/18 : (2 – 3)/4 = -2/18 : -1/4 = 1/9 : 1/4 = 4 : 9

Given:

Average of 14 numbers = 32

Average of last 5 number = 26

Formula used:

Average = Sum of all observation ÷ no. of observation

Calculation:

Sum of 14 number = 32 × 14

Sum of last 5 numbers = 5 × 26

∴ Average of remaining numbers $= \frac{{14; × ;32; - ;5; × ;26}}{{14; - ;5}} = \frac{{448; - ;130;}}{9} = \frac{{318;}}{9} = 35.33$

Given:

Ratio of Principal and Interest = 5 : 8

Time = 8 years

Formula used:

S.I. = (P × R × T)/100

where P → Principal 

R → rate of interest and 

T  → Time period

Calculation:

Principal : Interest = 5 : 8

So, S.I. = 8a and P = 5a

S.I. = (P × R × T)/100

⇒ 8a = (5a × R × 8)/100

∴ R = (100 × 8a)/(5a × 8) = 20%

Shortcut TrickRatio of Principal and Interest = 5 : 8

Total interest for 8 years = 8/5 × 100 = 160%

Interest per year = 160%/8 = 20%

Given:

The cost price of a watch is Rs. 530 and loss = 24%

Formula used:

C.P of the watch × loss% = Loss

Calculation:

C.P of the watch × 24/100 = Loss

⇒ 530 × 24/100 = Loss

∴ Loss = Rs. 127.2

Given:

C.P. of watch = Rs.300

Successive discount = 15% and 6%

Formula used:

S.P. = M.P. × {(100 - Discount₁)/100} × {(100 - Discount₂)/100}

Calculation:

⇒ S.P. = 300 × (100 - 15)/100 × (100 - 6)/100 .

⇒ 300 × 85/100 × 94/100 

∴ S.P. = 3 × 85 × 94/100 = 239.7

Calculation:

$\sqrt {12} - \frac{1}{{\sqrt 3 }} = 2\sqrt 3 - \frac{1}{{\sqrt 3 }} = \frac{{6; - ;1}}{{\sqrt 3 }} = \frac{5}{{\sqrt 3 }}$

Given:

Time taken by P = 15 days

Time taken by Q = 24 days

Concept used:

Total Work = Efficiency × Time

Calculation:

Let Total work = LCM of 15 and 24 = 120 units

Efficiency of P = 120/15 = 8 units/day

Efficiency of Q = 120/24 = 5 units/day

Total Efficiency of P and Q = 8 + 5 = 13 units/day

Total work done by Q in 2 days = 5 × 2 = 10 units

Now New Total work = 120 + 10 = 130 units

∴ Total time taken to complete the work = 130/13 = 10 days

Given:

Speed(S_A) of bus after repairing = 84km/h

Speed(S_B) of bus before repairing = 56km/h

Distance covered after repairing = 2x in 8 hours

Formula used:

Speed = Distance traveled/Time taken

Calculation:

S_A = Distance/Time

⇒ 84 = 2x/8

⇒ x = 84 × 4 = 336 km

S_B = Distance/Time = x/Time

⇒ 56 = 336/Time

∴ Time = 336/56 = 6 hours

Calculation:

As shown in the pie chart, the value of Marketing is 450 lakhs which is greater than any other expenditure.

So answer is Marketing.

Calculation:

Total Expenditure

⇒ Expenditure of (Faculty + Staff + Marketing + Rent + Assessments + Placements + Taxes)

∴ Total Expenditure = 300 + 150 + 450 + 250 + 200 + 300 + 150 = 1800

Calculation:

∴ The central angle of the sector representing Faculty

⇒ 300/1800 × 360° = 60°

Calculation:

Total expenditure on Assessments and Placements

⇒ 200 + 300 = 500

∴ Required Percentage = 500/1800 × 100 = 500/18 = 27.77%

Given:

The perimeter of rectangle = 60cm

The breadth of the rectangle = 14cm

The correct answer is life processes.

Explanation:

The basic essential activities performed by an organism to withstand its life are called as life processes. These include nutrition, respiration, circulation, excretion and reproduction. Organisms obtain energy from food to perform these life processes which are essential for survival. These are also termed maintenance processes.

The correct answer is Lack of Oxygen.

Explanation:

• When the body has plenty of oxygen, pyruvate is shuttled to an aerobic pathway to be further broken down for more energy.
• But when oxygen is limited, the body temporarily converts pyruvate into a substance called lactate, which allows glucose breakdown and thus energy production continues.
• The first step of respiration is the breakdown of glucose, a six-carbon molecule, into a three-carbon molecule called pyruvate.
• This process takes place in the cytoplasm.
• Further, the pyruvate may be converted into ethanol and carbon dioxide. This process takes place in yeast during fermentation. Since this process takes place in the absence of air (oxygen), it is called anaerobic respiration.
• Breakdown of pyruvate using oxygen takes place in the mitochondria. This process breaks up the three-carbon pyruvate molecule to give three molecules of carbon dioxide. The other product is water. Since this process takes place in the presence of air (oxygen), it is called aerobic respiration.
• The release of energy in this aerobic process is a lot greater than in the anaerobic process.
• Sometimes, when there is a lack of oxygen in the muscle cells, another pathway for the breakdown of pyruvate is taken.
• Here the pyruvate is converted into lactic acid which is also a three-carbon molecule.
• This build-up of lactic acid in our muscles during sudden activities like exercise causes cramps.
