The given equation is:

(7)² – (56 ÷ 8) + (9 × 6) = 18

Let's test the options to find the correct interchange that balances the equation.

Option 1: Interchange 8 and 6, and ÷ and +

The new equation becomes:

(7)² – (56 + 6) ÷ (9 × 8)

= (7)² – (56 + 6) ÷ (9 × 8)

= 49 – 62 ÷ 72

= 49 – 0.86

= 48.14 ≠ 18

This option is incorrect.

Option 2: Interchange 7 and 6, and + and –

The new equation becomes:

(6)² + (56 ÷ 8) – (9 × 7) = 18

= (6)² + (56 ÷ 8) – (9 × 7)

= 36 + 7 – 63

= 43 – 63

= −20 ≠ 18

This option is incorrect.

Option 3: Interchange 7 and 9, and – and +

The new equation becomes:

(9)² + (56 ÷ 8) – (7 × 6) = 18

= (9)² + (56 ÷ 8) – (7 × 6)

= 81 + 7 – 42

= 88 – 42

= 46 ≠ 18

This option is incorrect.

Option 4: Interchange 7 and 8, and – and +

The new equation becomes:

(8)² + (56 ÷ 7) − (9 × 6) = 18

= (8)² + (56 ÷ 7) − (9 × 6)

= 64 + 8 − 54

= 72 − 54

= 18

Since 18 = 18, the equation is correct.

Hence, the correct answer is "Option 4".

Given:

Average of four consecutive odd numbers A, B, C, and D = 14

Formula used:

Average = (Sum of all numbers) / (Number of terms)

For four consecutive odd numbers: A, B, C, D, we can represent them as:

A = x, B = x + 2, C = x + 4, D = x + 6

Calculation:

Average = (A + B + C + D) / 4

⇒ 14 = (x + (x + 2) + (x + 4) + (x + 6)) / 4

⇒ 14 = (4x + 12) / 4

⇒ 14 × 4 = 4x + 12

⇒ 56 = 4x + 12

⇒ 4x = 56 - 12

⇒ 4x = 44

⇒ x = 11

Now, A = x = 11, D = x + 6 = 11 + 6 = 17

Product of A and D = A × D

⇒ Product = 11 × 17

⇒ Product = 187

∴ The correct answer is option (4).

Given:

Selling Price (SP) = ₹26,650

Loss Percentage = 18%

Formula used:

Cost Price (CP) = \(\frac{SP}{1-\frac{\text{Loss %}}{100}}\)

Calculation:

CP = $\frac{26,650}{1-\frac{18}{100}}$

⇒ CP = $\frac{26,650}{1-0.18}$

⇒ CP = $\frac{26,650}{0.82}$

⇒ CP = ₹32,500

∴ The correct answer is option (4).

Given:

A finishes work in 7 days of 9 h/day ⇒ 7 × 9 = 63 h

B finishes work in 6 days of 7 h/day ⇒ 6 × 7 = 42 h

Working time per day together = 4 1/5 h = 4.2 h

Formula used:

Rate = Work ÷ Time

Calculations:

LCM method: Take LCM(63, 42) as total work (units).

⇒ LCM(63, 42) = 126 units

⇒ A’s rate = 126 ÷ 63 = 2 units/h

⇒ B’s rate = 126 ÷ 42 = 3 units/h

⇒ Together = 2 + 3 = 5 units/h

⇒ Time for full work = 126 ÷ 5 = 25.2 h

⇒ Days at 4.2 h/day = 25.2 ÷ 4.2 = 6

∴ They will finish in 6 days.

Given:

Monthly income of Mukesh = ₹75,000

Increase in income = 29%

Formula used:

New income = Original income × (1 + Percentage increase/100)

Calculations:

New income = 75,000 × (1 + 29/100)

⇒ New income = 75,000 × (1 + 0.29)

⇒ New income = 75,000 × 1.29

⇒ New income = ₹96,750

∴ The correct answer is option (4).

Given:

Initial Bill = ₹30,000

First Discount = 10%

Second Discount = 20%

Additional Discount = 10% (if net payment after first two discounts > ₹20,000)

Formula used:

Net Price after Discount = Price × (1 - Discount/100)

Calculation:

Apply the first discount of 10% on ₹30,000

⇒ Net Price = ₹30,000 × (1 - 10/100)

⇒ Net Price = ₹30,000 × 0.9

⇒ Net Price = ₹27,000

Apply the second discount of 20% on ₹27,000

⇒ Net Price = ₹27,000 × (1 - 20/100)

⇒ Net Price = ₹27,000 × 0.8

⇒ Net Price = ₹21,600

Check if the net price after two discounts is greater than ₹20,000

Since ₹21,600 > ₹20,000, apply an additional discount of 10%

⇒ Final Price = ₹21,600 × (1 - 10/100)

⇒ Final Price = ₹21,600 × 0.9

⇒ Final Price = ₹19,440

∴ The correct answer is option (2).

Given:

First number = 27

Second number = 108

Third number = 165

Formula used:

If a, b, c are given, the fourth proportional (x) is calculated using the formula:

(a : b = c : x) ⇒ x = (b × c) / a

Calculation:

x = (108 × 165) / 27

⇒ x = 17820 / 27

⇒ x = 660

∴ The fourth proportional to 27, 108, and 165 is 660.

Given:

The sum of two numbers is 60.

HCF = 5

LCM = 175

Formula used:

If HCF × LCM = Product of two numbers, then the numbers can be expressed as:

Let numbers = 5a and 5b, where a and b are co-prime.

Sum of reciprocals of two numbers = $\dfrac{1}{\text{Number 1}} + \dfrac{1}{\text{Number 2}}$.

Calculation:

HCF × LCM = Product of two numbers

⇒ 5 × 175 = 875

Let numbers = 5a and 5b

Product = 5a × 5b = 875

⇒ a × b = 35

Sum of numbers = 5a + 5b = 60

⇒ a + b = 12

From a × b = 35 and a + b = 12:

⇒ a and b are roots of the equation x² - 12x + 35 = 0

⇒ (x - 7)(x - 5) = 0

⇒ x = 7, 5

Numbers are 5a = 35 and 5b = 25.

Sum of reciprocals:

⇒ $\dfrac{1}{35} + \dfrac{1}{25}$

⇒ $\dfrac{5 + 7}{175}$

⇒ $\dfrac{12}{175}$

∴ The correct answer is option (1).

Given:

Dimensions of the cuboid:

Length (l) = 256 cm

Breadth (b) = 135 cm

Height (h) = 50 cm

The cuboid is melted and recast into a cube.

Formula used:

Volume of cuboid = l × b × h

Volume of cube = a³, where a = side of the cube

Surface area of cube = 6a²

Calculation:

Volume of cuboid = 256 × 135 × 50

⇒ Volume of cuboid = 1,728,000 cm³

Volume of cube = Volume of cuboid

⇒ a³ = 1,728,000

⇒ a = ∛1,728,000 = 120 cm

Surface area of cube = 6a²

⇒ Surface area = 6 × 120 × 120

⇒ Surface area = 86,400 cm²

∴ The correct answer is option (3).

Given:

Difference (CI − SI) = ₹964

Rate (r) = 20% per annum

Time (t) = 2 years

Formula used:

Difference for 2 years = P × (r/100)²

Calculations:

⇒ 964 = P × (20/100)²

⇒ 964 = P × (400/10000)

⇒ 964 = P × (1/25)

⇒ P = 964 × 25

⇒ P = 24,100

∴ The sum is ₹24,100.

Given:

Reeta finishes 28 m ahead of Sita.

Geeta finishes 40 m ahead of Reeta.

Geeta finishes 64 m ahead of Sita.

Formula used:

For uniform speeds, distances covered are proportional to times; ratios of distances remain constant.

Calculations:

Let total distance = y m.

When Geeta finishes: Geeta = y, Reeta = y − 40, Sita = y − 64.

Ratio Reeta : Sita = (y − 40) : (y − 64)

When Reeta finishes: Reeta = y, Sita = y − 28.

Ratio Reeta : Sita = y : (y − 28)

⇒ (y − 40)/(y − 64) = y/(y − 28)

⇒ (y − 40)(y − 28) = y(y − 64)

⇒ y² − 28y − 40y + (40 × 28) = y² − 64y

⇒ y² − 68y + 1120 = y² − 64y

⇒ −68y + 1120 = −64y

⇒ 1120 = 4y

⇒ y = 1120 ÷ 4 = 280

∴ The race distance y = 280 m.

The Correct answer is when the road ahead is not visible.

Key Points

• Overtaking is a critical maneuver that requires clear visibility of the road ahead to ensure safety.
• It is dangerous to overtake when the road ahead is not visible, as it increases the risk of collision with oncoming vehicles.
• This situation often arises on sharp curves, hilly terrains, blind spots, or areas with dense fog, where visibility is severely limited.
• Overtaking in such conditions can lead to accidents due to the inability to predict the movement of other vehicles or obstacles.
• Adherence to traffic rules and exercising caution while overtaking is essential for road safety.
• In many countries, including India, traffic laws explicitly prohibit overtaking in areas where visibility is obstructed or limited.
• Maintaining a safe distance and waiting for the road ahead to become visible is a prudent decision while driving.

Additional Information

• When there is no signal to overtake from the vehicle ahead
• While it is courteous to wait for a signal from the vehicle ahead, it is not mandatory in all driving conditions.
• Drivers should rely on their judgment, road conditions, and visibility while overtaking, rather than solely waiting for a signal.
• When the road ahead is visible
• Overtaking is generally considered safe when the road ahead is clearly visible and free from obstacles.
• Drivers need to ensure there is sufficient space and time to complete the maneuver safely.
• When you cannot see vehicles coming from the other side
• Inability to see vehicles from the opposite direction can be a result of poor visibility or road obstructions.
• This condition is closely related to the correct answer and emphasizes the importance of clear visibility before overtaking.

The Correct answer is Proceed slowly and cautiously since there is chance of students suddenly crossing the road.

Key Points

• When a school bus is stopped for picking up or setting down students, it is important to be extremely cautious to ensure the safety of children.
• Children are often unpredictable and may suddenly cross the road without looking for oncoming traffic.
• Drivers must proceed slowly and cautiously to minimize the risk of accidents and allow students to cross the road safely.
• Stopping or slowing down near a school bus ensures compliance with road safety regulations in many countries, which prioritize the protection of young pedestrians.
• School buses often display warning signs or flashing lights while stopped, indicating drivers to exercise caution and reduce speed.
• Being attentive and vigilant in such situations helps to prevent accidents and promotes a safer environment for both students and other pedestrians.
• Road safety awareness campaigns often emphasize the importance of cautious driving near school zones or buses.

Additional Information

• No special care is required
• This option is incorrect because special care is always required when driving near school buses to protect children, who are vulnerable and less aware of traffic rules.
• Children may be impulsive and not follow standard pedestrian behavior, making careful driving essential.
• Blow horn and proceed
• Blowing the horn near a school bus may and is not a recommended safety practice.
• Instead, drivers are advised to be calm and cautious without causing unnecessary noise or disturbance.
• Move fast
• Moving fast near stopped school buses can be extremely and lead to accidents involving students crossing the road.
• This behavior violates basic and can result in legal penalties in many regions.

The Correct answer is Multi Point Fuel Injection System.

Key Points

• Multi Point Fuel Injection (MPFI) System is a technology used in modern automobiles.
• It involves the precise injection of fuel into each cylinder of the engine using multiple injectors.
• MPFI systems enhance the engine's efficiency, fuel economy, and performance.
• This system ensures an optimized air-fuel mixture, leading to better combustion and reduced emissions.
• It is commonly used in vehicles powered by petrol engines.
• The MPFI system is controlled by an Electronic Control Unit (ECU), which regulates the fuel injection timing and quantity based on various inputs like engine speed, temperature, and load.
• Compared to older technologies like carburetors, MPFI systems provide greater precision and are more suitable for meeting stringent emission norms.
• Examples of vehicles equipped with MPFI technology include modern passenger cars and light commercial vehicles.

Additional Information

• Multi-Port Fuel Injection System
• While the term is similar, "Multi-Port" often refers to the location or arrangement of the injectors at multiple intake ports. However, the correct term for the technology widely used in automobiles is Multi Point Fuel Injection System.
• Multi-Port Fuel Ignition System
• This term incorrectly mixes "Fuel Injection" with "Ignition." Ignition systems are separate mechanisms designed for sparking fuel combustion rather than injecting fuel.
• Multi Point Fuel Ignition System
• Similar to the previous option, this term combines "Fuel Injection" and "Ignition," which are fundamentally different processes.
• In an engine, Fuel Injection deals with delivering fuel, while Ignition triggers combustion through spark plugs.

The Correct answer is connecting rod.

Key Points

• The connecting rod is a crucial component in an internal combustion engine that transmits motion from the piston to the crankshaft.
• It acts as a link between the piston, which moves linearly, and the crankshaft, which rotates.
• When the fuel undergoes combustion inside the cylinder, it produces a sudden rise in pressure, which pushes the piston downwards.
• The connecting rod transfers this linear motion of the piston to the rotational motion of the crankshaft.
• During this process, the connecting rod also transmits the shock caused by the sudden rise in pressure to the crankshaft.
• The layer of oil in the main bearings absorbs this shock, ensuring smooth operation and reducing wear and tear.
• Connecting rods are typically made of strong materials like forged steel or aluminum alloys to withstand high pressure and temperature conditions.
• Proper lubrication of the connecting rod bearings is essential to prevent friction and overheating, which could lead to engine failure.

Additional Information

• Camshaft
• The camshaft is responsible for controlling the timing of the opening and closing of the engine's valves.
• It does not play a role in transmitting the force generated by combustion; rather, it synchronizes the operation of the intake and exhaust valves with the movement of the piston.
• The camshaft is typically connected to the crankshaft via a timing belt or chain.
• Flywheel
• The flywheel is a rotating mechanical device that stores rotational energy and helps maintain a steady speed of the crankshaft.
• It is not directly involved in transmitting the combustion force but helps in evening out the power strokes in the engine cycle.
• Flywheels are commonly found in both internal combustion engines and electric motors.
• Crankshaft
• The crankshaft converts the reciprocating motion of the piston (via the connecting rod) into rotational motion.
• It is connected to the connecting rod and is a key component in transmitting the engine's power to the drivetrain.
• The crankshaft is generally made from forged steel or cast iron to ensure durability and strength.

The Correct answer is Turn the steering wheel in the direction the car is skidding.

Key Points

• When a vehicle starts to skid, it is often due to loss of traction between the tires and the road surface, which can be caused by slippery conditions such as rain, ice, or snow.
• Turning the steering wheel in the direction the car is skidding helps to regain control of the vehicle by aligning the tires with the direction of motion.
• This technique is effective because it reduces the imbalance and helps the vehicle to stabilize, preventing further spinning or swerving.
• It is important to avoid making sudden or jerky movements with the steering wheel, as this can worsen the skid.
• Drivers should remain calm during a skid and gently turn the wheel while keeping their focus on where they want the car to go.
• The method is widely recommended by driving experts and included in defensive driving courses globally.
• This action also works best when combined with releasing the accelerator and refraining from braking, as braking can cause further loss of traction.

Additional Information

• Put on the brake first
• Applying brakes during a skid can worsen the situation as it leads to further loss of traction.
• Braking abruptly can lock the wheels, especially in vehicles without anti-lock braking systems (ABS), making it harder to regain control.
• Accelerate vehicle
• Accelerating during a skid is not recommended as it can cause the vehicle to lose even more control.
• Acceleration increases the force and momentum, worsening the skid in slippery conditions.
• Do nothing
• Doing nothing during a skid is dangerous because it allows the vehicle to continue spinning or sliding uncontrollably.
• Inaction prevents corrective measures from being taken, increasing the likelihood of an accident.

The Correct answer is You will not blow horn.

• By dissipating excess heat generated during combustion, the cooling system ensures the engine operates efficiently.
• Emission System
• The emission system is responsible for reducing harmful pollutants released by the vehicle.
• It includes components such as the catalytic converter, exhaust manifold, and oxygen sensors.
• This system ensures compliance with emission standards set by regulatory authorities.
• Lubrication System
• The lubrication system ensures that engine components are properly lubricated to reduce friction and wear.
• It includes components such as the oil pump, oil filter, and oil pan.
• This system also helps in cooling engine parts and preventing corrosion.

The Correct answer is 2000.

Key Points

• Euro emission standards are a set of regulatory measures aimed at controlling the emission of pollutants from vehicles.
• The implementation of these standards is essential for reducing the environmental impact of vehicular emissions.
• India adopted the Euro I standards in the year 2000 as a part of its efforts to combat air pollution.
• These standards were introduced nationwide in India, marking a significant move towards improving air quality and ensuring compliance with global environmental norms.
• The Euro norms regulate the emission of critical pollutants such as carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and particulate matter (PM).
• Adoption of Euro standards in India also led to advancements in automobile technology, promoting the use of cleaner fuels and improved engine designs.
• The implementation of Euro norms paved the way for subsequent iterations, including Bharat Stage emission standards, which are modeled on Euro standards.

Additional Information

• 1999
• No significant nationwide emission standard was introduced in India in 1999.
• 2001
• India implemented stricter emission standards after 2000, but 2001 was not the year of initial implementation.
• 1998
• Emission standards were not implemented on a nationwide scale in India during 1998.

The Correct answer is The type of tyres used.

Key Points

• The type of tyres used is not a relevant factor in differentiating between a spark ignition (SI) engine and a compression ignition (CI) engine.
• Tyres are a part of the vehicle's design, not the engine's operational mechanism.
• The differentiation between SI and CI engines is based on factors such as fuel type, fuel entry mechanism, and ignition method, not external components like tyres.
• Both SI and CI engines can use the same tyre types depending on the vehicle's design and purpose, making this parameter unrelated to engine differences.
• This question highlights the importance of focusing on the engine's internal workings rather than unrelated vehicle components.

Additional Information

• The type of fuel used
• Spark Ignition (SI) engines typically use fuels like gasoline, which are more volatile and require an external ignition source (spark plug).
• Compression Ignition (CI) engines use fuels like diesel, which ignite due to high-pressure compression without the need for a spark plug.
• This fuel distinction is a key difference between the two engine types.
• The way the fuel enters the combustion chamber
• In SI engines, fuel enters the combustion chamber via a carburetor or fuel injection system that mixes air with fuel before delivering it.
• In CI engines, fuel is injected directly into the combustion chamber under high pressure, ensuring proper atomization and mixing.
• This mechanism is a critical factor in engine operation and efficiency.
• The way in which fuel is ignited
• SI engines rely on a spark plug to ignite the air-fuel mixture.
• CI engines ignite fuel through compression ignition, where high pressure and temperature cause spontaneous combustion.
• This ignition difference is a primary distinction between the two engine types.
