Given:

A policeman starts to chase a thief. When the thief goes 12 steps, the policeman moves 9 steps.

6 steps of the policeman = 9 steps of the thief.

Formula used:

Speed = Distance / Time

To find the ratio of the speed of the thief to that of the policeman:

Speed of thief / Speed of policeman = (Distance covered by thief in 1 step) / (Distance covered by policeman in 1 step).

Calculation:

Let the distance covered by the thief in 1 step = T and the distance covered by the policeman in 1 step = P.

6P = 9T

⇒ P / T = 9 / 6

⇒ P / T = 3 / 2

In the given time, the thief takes 12 steps, and the policeman takes 9 steps:

Speed of thief / Speed of policeman = (12 × T) / (9 × P)

⇒ Speed of thief / Speed of policeman = (12 × T) / (9 × (3T / 2))

⇒ Speed of thief / Speed of policeman = (12) / (9 × 3 / 2)

⇒ Speed of thief / Speed of policeman = (12 × 2) / (27)

⇒ Speed of thief / Speed of policeman = 24 / 27

⇒ Speed of thief / Speed of policeman = 8 / 9 = 8 : 9

∴ The correct answer is  8 : 9

Given:

Given:

Marked price (MP) = ₹7,200

Cost price (CP) = 70% below the marked price

Successive discounts = 25% and 25%

Further discount = 18% on net payment

Formula used:

Cost Price (CP) = MP × (1 - Discount %)

Successive Discount = MP × (1 - First Discount %) × (1 - Second Discount %)

Further Discount = SP × (1 - Discount %)

Profit Percentage = [(SP - CP) / CP] × 100

Calculations:

Cost Price:

⇒ CP = 7200 × (1 - 70/100)

⇒ CP = 7200 × 0.3 = ₹2,160

Selling Price after successive discounts:

⇒ SP after first two discounts = 7200 × (1 - 25/100) × (1 - 25/100)

⇒ SP after first two discounts = 7200 × 0.75 × 0.75

⇒ SP after first two discounts = ₹4,050

Selling Price after further discount:

⇒ Final SP = SP after first two discounts × (1 - 18/100)

⇒ Final SP = 4050 × 0.82

⇒ Final SP = ₹3,321

Profit Percentage:

⇒ Profit = Final SP - CP

⇒ Profit = 3321 - 2160 = ₹1,161

⇒ Profit Percentage = (Profit / CP) × 100

⇒ Profit Percentage = (1161 / 2160) × 100

⇒ Profit Percentage ≈ 53.75% = 54%

∴ The correct answer is 54%

Given:

6 men and 4 boys can finish a work in 20 days.

4 men and 6 boys can finish the same work in 24 days.

We need to find the number of days 2 boys and 1 man can finish the work.

Formula used:

Work = (Efficiency × Time)

Efficiency of a group = Total work / Time

Calculation:

Let the efficiency of 1 man be m and 1 boy be b.

Total work = Efficiency × Time

For 6 men and 4 boys:

Work = Efficiency × Time

⇒ (6m + 4b) × 20

⇒ Total work = 120m + 80b

For 4 men and 6 boys:

Work = Efficiency × Time

⇒ (4m + 6b) × 24

⇒ Total work = 96m + 144b

Equating the two total works:

⇒ 120m + 80b = 96m + 144b

⇒ 24m = 64b

⇒ m = 64b / 24

⇒ m = 8b / 3

Now, find the efficiency of 2 boys and 1 man:

Efficiency = (1m + 2b)

⇒ Efficiency = (8b / 3) + 2b

⇒ Efficiency = (8b / 3) + (6b / 3)

⇒ Efficiency = 14b / 3

Total work from the first case:

Total work = (6m + 4b) × 20

⇒ Total work = 120m + 80b

Substitute m = 8b / 3:

⇒ Total work = 120(8b / 3) + 80b

⇒ Total work = (960b / 3) + (240b / 3)

⇒ Total work = 1200b / 3

⇒ Total work = 400b

Time for 2 boys and 1 man:

Time = Total work / Efficiency

⇒ Time = 400b / (14b / 3)

⇒ Time = (400b × 3) / 14b

⇒ Time = 1200 / 14

⇒ Time = 85.7 days

∴ The correct answer is option (3).

The correct answer is impact.

Key Points

• Leaf springs are a type of suspension system used in vehicles, including cars, to provide support and absorb shocks.
• The curvature of leaf springs helps them to effectively absorb impact forces that occur when the car moves over bumps, potholes, or uneven surfaces.
• When an impact occurs, the curvature of the spring allows it to flex, thereby dissipating the energy of the shock and reducing the force transmitted to the vehicle body.
• Leaf springs are designed to handle both vertical loads and the forces generated during braking and acceleration.
• They are commonly used in the suspension systems of trucks, buses, and older car models, as they are robust and cost-effective.
• The specific design of the curvature also ensures that the spring can return to its original shape after the impact force is absorbed, maintaining vehicle stability and ride comfort.
• This property of leaf springs contributes to the durability and longevity of the suspension system.

Additional Information

• Tension
• Tension refers to a pulling force transmitted through a string, rope, or similar object.
• In mechanical systems, tension is not a primary function of leaf springs, as they are designed to handle compression and bending forces rather than pulling forces.
• Compression
• Compression involves forces that attempt to shorten or squeeze a material.
• While leaf springs experience compression as part of their operation, their primary role is to absorb impact forces, which may include both compression and bending.
• Twisting
• Twisting refers to torsional forces applied to an object.
• Leaf springs are not designed to handle significant twisting forces, as their primary purpose is to absorb vertical impacts and maintain suspension stability.

The Correct answer is 55 dB(A) Leq.

• This indicates the maximum vehicle height allowed to pass under a bridge, tunnel, or overhead structure.
• The sign generally includes a measurement in meters or feet with vertical arrows.
• Used in areas with low-clearance obstacles to prevent collisions with over-height vehicles.

The Correct answer is Right hair pin bend.

Key Points

• This traffic sign is a warning sign, indicated by its triangular shape with a red border.
• The symbol inside the triangle represents a hump or elevation on the road surface.
• It is officially known as the “Hump or Uneven Road Ahead” or “Right hairpin bend” warning sign.
• It alerts drivers to an upcoming speed breaker, hump, or sudden road elevation to help reduce speed and prevent accidents.
• This sign is particularly common in areas like school zones, hospital zones, residential areas, or intersections.
• According to Indian Road Congress (IRC) guidelines and traffic control manuals followed in many countries, this sign is part of the cautionary signs category.
• The purpose is to maintain road safety by giving advance notice so the driver can slow down accordingly.
• Disregarding this warning can lead to vehicle damage or loss of control, especially at high speeds.

Additional Information

• Left hand turn
• This is indicated by a different warning sign, usually showing a left-pointing curved arrow inside a red-bordered triangle.
• It alerts drivers about a left curve or bend ahead and is important for preventing sharp turn collisions.
• Right hand turn
• This sign shows a right-pointing curved arrow and warns drivers of a rightward curve ahead.
• It helps in reducing speed before taking the turn to avoid skidding or overshooting.
• Right hair pin bend
• This sign indicates a very sharp right turn or U-bend, often found in hilly terrains or mountain roads.
• The symbol used in this case is more angular and shows a tight U-shaped curve to the right.
• Such areas are known for accident-prone zones due to the sharpness of the curve.

The Correct answer is wax.

Key Points

• Car wax is a product specifically designed to provide a protective layer over the car's paint.
• It enhances the car's appearance by giving it a shiny and polished look.
• The application of wax is crucial as it protects the car paint from external elements like dirt, grime, and harmful ultraviolet radiation (UV rays).
• Wax acts as a barrier to prevent the car's paint from fading or peeling due to prolonged exposure to sunlight.
• Car wax comes in various forms, including paste, liquid, and spray formulations, offering flexibility in application.
• Many waxes contain natural ingredients like carnauba wax, which is highly regarded for its durability and sheen.
• Regular application of wax helps maintain the car's aesthetic appeal and preserves its resale value.
• Using high-quality wax ensures better protection and longer-lasting effects compared to cheaper alternatives.

Additional Information

• Oil
• Oil is primarily used for lubrication of the engine and other mechanical parts in vehicles, not for exterior protection or shine.
• It ensures smooth functioning of internal components by reducing friction and wear.
• Common types include synthetic oil, conventional oil, and high-mileage oil.
• Paint
• Paint is the primary coating applied to a car to give it color and protect the surface from corrosion.
• While paint provides initial protection, it cannot resist long-term exposure to UV radiation and other environmental factors without an additional layer like wax.
• Paint comes in various finishes, such as metallic, matte, and gloss.
• Coolant
• Coolant is a liquid used to regulate the temperature of a car's engine and prevent overheating.
• It plays no role in enhancing the car's exterior shine or protecting the paint.
• Coolants consist of a mixture of water and antifreeze compounds, such as ethylene glycol.
