Explanation :

Conclusion I. Arijit Singh has a good voice.

False  (This does not follow as statement is talking about peace of mind which music gives and there is no relation between statement and conclusion)

Conclusion II. Kishor Kumar was a famous singer.

False (This also does not follow as kishore kumar is a famous singer but it does not relate with peace of mind.)

Hence, Neither of the conclusion follows is the correct answer.

Distance covered by 1 round = perimeter of the circle

2πr = 1100

⇒ 2 × 22/7 × r = 1100

⇒ r = 1100 × 7/22 × 1/2

⇒ r = 175 cm

∴ Diameter of the wheel = 2 × 175 = 350 cm

• W = work interaction of the system with its surroundings

The pattern followed here is:

According to the alphabetical positions of the letters,

Similarly,

Hence, ‘WLSAIV’ is the correct answer.

Given:

Ratio of the outer and the inner perimeter of the a circular path = 14 : 11

Width of the path = 15 m

Formula:

Perimeter of the circle = 2 πr

Calculation:

Let the radius of outer and inner circle be R and r m, then

Circumference of outer circle = 2 πR

Circumference of inner circle = 2 πr

According to the question

2 πR/2 πr = 14/11

⇒ R/r = 14/11

⇒ R : r = 14x : 11x

Length of path (R – r) = 15 m

14x – 11x = 15

⇒ 3x = 15

⇒ x = 15/3

⇒ x = 5

∴ Radius of inner circle = 11x = 11 × 5 = 55 m

Given,

 August 20, 1900, = Saturday

The total days between 20 August 1900 to 20 August 1905 is 5 years.

1900 =  Normal year (365 days = 1 odd day)

1901 =  Normal year (365 days = 1 odd day)

1902 =  Normal year (365 days = 1 odd day)

1903 =  Normal year (365 days = 1 odd day)

1904 =  Leap year (366 days = 2 odd day)

Total odd day = 1 + 1 + 1 + 1 + 2 = 6 days

So, Saturday + 6 days = Friday

Hence, the correct answer is "Friday".

HintLeap Year = ( 52 weeks + 2 Odd day)

Non-leap year  = (52 weeks + 1odd day)

Given:

The wheel makes 4000 revolutions to cover a distance 60 km

Concept Used:

Circumference of a circle of radius r is 2πr

Calculation:

Distance is 60 km = 60000 meter

Total number of revolution is 4000

In one revolution distance covered = 60000/4000 meter

⇒ 15 meter

Let, the radius of the wheel be r

2πr = 15

⇒ 2 × (22/7) × r = 15

⇒ r = 15 × (7/ 22) × (1/2)

⇒ r = 105/44

⇒ r = 2.3863..

⇒ r = 2.39

∴ The radius of the wheel is 2.39 meter

Hence, Only (II) follow is the correct answer.

Important Points

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)]%.

400 - 216 = 184

184 = 184 (LHS = RHS)

Hence, "Option - (4)" is the correct answer.

Given: A and B were two candidates in an election.

A got 55% of the total votes.

10% of the total population did not cast any votes.

B got a total of 11000 votes.

Concept: Percentage increase/ decrease = (new - actual)/actual × 100%

Calculation:

Let total population be 100x.

10% of the total population did not cast any vote.

That means 90x voters cast their votes.

A got 55% of the total votes casted and B got a total of 11000 votes.

B got 45% of the votes.

According to the question,

45/100 × 90x = 11000

⇒ x = 271.6

Total population = 100 × 271.6 = 27160

∴ The total population is 27160.

The correct answer is a seismic wave.

Key Points

• An elastic wave generated by an impulse such as an earthquake or an explosion is called a seismic wave.
• Seismic waves are waves of energy that travel through Earth's layers and are a result of earthquakes, volcanic eruptions, magma movement, large landslides, and large man-made explosions that give out low-frequency acoustic energy.
• Earthquakes are usually caused when the underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes seismic waves that make the ground shake.
• The earthquake is over when the fault stops moving. Seismic waves are generated throughout the earthquake.
• Three fundamental kinds of seismic waves are Primary (P = pressure) waves, Secondary (S = shear), and Surface waves.
• Seismic waves may travel either along or near the earth's surface (Rayleigh and Love waves) or through the earth's interior (P and S waves).

Given :

(cotθ - tanθ)/(2 tanθ) = 3/4

Formula used :

tan θ = 1/cot θ 

cosθ = base/hypotenuse 

sinθ = perpendicular/hypotenuse 

Calculations :

(cotθ - tanθ)/(2 tanθ) = 3/4

⇒ (cotθ - tanθ)/(tanθ) = 3/2 

⇒ 2cotθ - 2tanθ = 3tanθ 

⇒ 2 cot θ - 2/cot θ = 3/cot θ 

⇒ (2cot²θ - 2)/cot θ  = 3/cot θ  

⇒ 2cot²θ = 5

⇒ cot2θ = 5/2

⇒ cotθ = √(5/2) 

cosθ = √(5/7) and sinθ = √(2/7) 

Now, 

cos²θ - sin²θ = (5/7) - (2/7) 

⇒ 3/7 

∴ 3/7 is the right answer

• The Act marked a second milestone towards a completely responsible government in India. It was a lengthy and detailed document having 321 Sections and 10 Schedules.

Additional Information

• The features of this Act were as follows:  
• It provided for the establishment of an All-India Federation consisting of provinces and princely states as units.
• The Act divided the powers between the Centre and units in terms of three lists–Federal List (for Centre, with 59 items), Provincial List (for provinces, with 54 items) and the Concurrent List (for both, with 36 items).
• Residuary powers were given to the Viceroy.
• However, the federation never came into being as the princely states did not join it.
• It abolished dyarchy in the provinces and introduced ‘provincial autonomy’ in its place.
• The provinces were allowed to act as autonomous units of administration in their defined spheres.
• Moreover, the Act introduced responsible Governments in provinces, that is, the Governor was required to act with the advice of ministers responsible to the provincial legislature.
• This came into effect in 1937 and was discontinued in 1939.
• It provided for the adoption of dyarchy at the Centre.
• Consequently, the federal subjects were divided into reserved subjects and transferred subjects.
• However, this provision of the Act did not come into operation at all.
• It introduced bicameralism in six out of eleven provinces.
• Thus, the legislatures of Bengal, Bombay, Madras, Bihar, Assam and the United Provinces were made bicameral consisting of a legislative council (upper house) and a legislative assembly (lower house).
• However, many restrictions were placed on them.
• It further extended the principle of communal representation by providing separate electorates for depressed classes (Scheduled Castes), women and labor (workers).
• It abolished the Council of India, established by the Government of India Act of 1858.
• The secretary of state for India was provided with a team of advisors.
• It extended the franchise. About 10 percent of the total population got the voting right.
• It provided for the establishment of a Reserve Bank of India to control the currency and credit of the country.
• It provided for the establishment of not only a Federal Public Service Commission but also a Provincial Public Service Commission and Joint Public Service Commission for two or more provinces.
• It provided for the establishment of a Federal Court, which was set up in 1937.

The correct answer is Impulse.

Key Points

• Impulse is the effect of impulsive force.
• Impulse is the force that changes the momentum of a body,
• Impulse has the same dimension as that of linear momentum.
• Impulse(I) = Force(F) × Time(V).
• Dimensional formulae of force and time are [MLT^-2] and [T] respectively.
• Dimensional formulae of Impulse = MLT^-1 → (A)
• Linear momentum is defined as the product of the mass (m) of an object and the velocity (v) of the object.
• Linear momentum = Mass × Velocity
• Dimensional formulae of mass and velocity are [M] and [LT⁻¹] respectively.
• Dimensional formulae of Linear momentum = MLT^-1 → (B)
• ∴ (A) = (B)
• Dimensional formulae of Linear momentum= Dimensional formulae of Impulse.

The statement above discusses the point of a mouse being an input device.

The first argument is in favour of the statement above, as it mentions the actions performed by a mouse.

Since it is used to send data inside a computer, it can be called an input device.

Hence, argument I is a strong argument.

The second argument is not in favour of calling a mouse as an input device just because it is physically present outside the computer.

This reason is not appropriate enough to deny the above-mentioned statement.

Hence, argument II is a weak argument.

Given:

Pipe A = Takes 40 minutes to fill

Pipe B = Takes 120 minutes to empty

Formula Used:

(1/ t) = (1/ a) - (1/ b)

where a is time taken by pipe A to fill the tank and b is time taken by B to empty the tank

Calculation:

Here, a = 40 and b = 120,

(1/ t) = (1/ 40) - (1/ 120)

⇒ (1/ t) = (3 - 1)/ 120

⇒ (1/ t) = (2/120)

⇒  t = 60

∴ t = 60 minutes

Alternate Method

Convert minutes into efficiency

Take LCM of 40 and 120

LCM (40, 120) = 120

Now, units of time taken by pipe A = 120/ 40

⇒ Units = 3 

Units of time taken by pipe B = 120/ 120

⇒ Units = 1

Time taken by tank to fill the whole tank when both pipes are open = 120/ (3 - 1)

⇒ T = 60 minutes

∴ T = 60 minutes

The series follows an Alternate pattern in the following way:

The next element in the series will be 170.

Hence, the correct answer is Option (4).

Given: 

Amount to in 1 year = Rs. 4818

Amount to in 4 years = Rs. 6072

Concept used:

SI = Prt/100

P → princiapl R → rate of interest T → time

Calculation:

Simple interest of 3 years = 6072 – 4818 = 1254

Simple Interest of 1 year = 1254/3 = 418

Principal = 4818 – 418 = Rs. 4400

⇒ 418 = (4400 × r × 1)/100

⇒ r = (418/4400) × 100 = 9.5%

∴Rate of interest is 9.5%.

Shortcut Trick

The extra time taken to cross the tunnel compared to the pole is used to cover the tunnel length.

Time difference = 20 s − 5 s = 15 s

Tunnel Length = Speed × Time difference = 90 × 15 = 1350 m.

∴ The correct answer is 1350 m.

Alternate Method

Given:

Speed of the train = 90 m/s

Time taken to cross a pole (t₁) = 5 s

Time taken to cross the tunnel (t₂) = 20 s

Formula Used:

Distance = Speed × Time

When crossing a pole, Distance = Length of Train (L_T)

When crossing a tunnel, Distance = Length of Train (L_T) + Length of Tunnel (L_Tunnel)

Train

Pole

Tunnel

t1 = 5s

t2 - t1 = 15s
Speed = 90 m/s

Calculations:

⇒ L_T = 90 × 5 = 450 m

⇒ L_T + L_Tunnel = 90 × 20

⇒ 450 + L_Tunnel = 1800

⇒ L_Tunnel = 1800 − 450

⇒ L_Tunnel = 1350 m

∴ The correct answer is 1350 m.

Additional Information

Train Crossing Stationary Objects

When a train crosses a pole or a standing person, it covers a distance equal to its own length. When it crosses a platform or tunnel, it covers Distance = Length of Train + Length of Object.

Unit Conversion

To convert speed from km/hr to m/s, multiply by 5/18. To convert m/s to km/hr, multiply by 18/5.

Relative Speed

If two trains of lengths L₁ and L₂ cross each other, the total distance covered is always L₁ + L₂. Relative speed is S₁ + S₂ in opposite directions and |S₁ − S₂| in the same direction.

Given:

Successive discounts of  the earphone was 15% and 8%

Selling Price of  the earphone is Rs. 3128

Formula used:

Net discount = [a + b - (ab)/100]%

Where,

a = first discount rate of the earphone

b = second discount rate of the earphone

Calculation:

Let cost price of the earphone be Rs. x

a = 15%, b = 8%

Net discount = [15 + 8 - (15 × 8)/100]%

⇒ Net discount = [23 - (120)/100] 

⇒ Net discount = [23 - 1.2] = 21.8%

⇒ Marked up price of the earphone × (100 - Net discount)/100 = 3128

⇒ x × (100 - 21.8)/100 = 3128

⇒ x × 78.2/100 = 3128

⇒ x = 4000

∴ The marked up price of the earphone is Rs. 4000.

Answer: option 3. Neither assumption I nor II is implicit.

Both the assumptions are not implicit as the statement does not give any information about the people who indulge in folk music. Hence, neither assumption I nor II is implicit.

Shortcut Trick

Total work = LCM(18, 30) = 90 units.

Efficiency of (A + B) = 90 ÷ 18 = 5 units and (B + C) = 90 ÷ 30 = 3 units.

Difference in efficiency: (A + B) − (B + C) = A − C = 5 − 3 = 2 units.

Given A = 2C, so 2C − C = 2 ⇒ C's efficiency = 2 units.

Efficiency of B = Eff(B + C) − Eff(C) = 3 − 2 = 1 unit.

Time taken by B alone = 90 ÷ 1 = 90 days.

∴ The correct answer is 90 days.

Alternate Method

Given:

Time taken by (A + B) = 18 days

Time taken by (B + C) = 30 days

Efficiency of A = 2 × Efficiency of C

Formula Used:

Efficiency = Total Work ÷ Time taken

⇒ Efficiency of (A + B) = 5

⇒ Efficiency of (B + C) = 3

⇒ (A + B) − (B + C) = 5 − 3

⇒ A − C = 2

⇒ Since A = 2C, substitute A: 2C − C = 2 ⇒ C = 2 units/day

⇒ Efficiency of B = (B + C) − C = 3 − 2 = 1 unit/day

⇒ Days taken by B alone = Total Work ÷ Efficiency of B

⇒ Days taken by B = 90 ÷ 1 = 90 days

∴ The correct answer is 90 days.

Additional Information

Total Work Concept

Total Work = Efficiency × Time. When work is constant, Efficiency is inversely proportional to Time.

Efficiency Comparison

If A is n times as good as B, then the ratio of their efficiencies is n : 1 and the ratio of time taken to complete the same work is 1 : n.

Combined Work Rule

If person X takes x days and Y takes y days, together they take (x × y) ÷ (x + y) days to complete the work.
