Step 3: Calculate Car B's distance using the value of x.
Calculation: 4x = 4 × 50 = 200 km.
Explanation:
Step 2: Both units are compatible (meters per second and seconds).
Calculation: 15 × 10 = 150 meters.
Explanation:
Calculation: Speed = 300 / 5 = 60 km/h.
Explanation:
Step 2: (20 / 100) × 800 = Rs 160.
Step 3: Subtract the loss from the Cost Price.
Calculation: Selling Price = 800 - 160 = Rs 640.
Explanation:
Step 2: The expression becomes 100 ÷ 20 × 5.
Step 3: Perform division next: 100 ÷ 20 = 5.
Calculation: Perform multiplication: 5 × 5 = 25.
Explanation:
Calculation: 15 × (18 / 5) = 3 × 18 = 54 km/h.
Explanation:
Calculation: Time = 300 / 75 = 4 hours.
Explanation:
Calculation: Distance = 50 × 1.5 = 75 km.
Explanation:
Calculation: 4 × 4500 = 18000.
Explanation:
Calculation: (25 / 100) × 40 = (1 / 4) × 40 = 10 liters.
Explanation:
Step 2: Calculate the average: Total Weight / Number of packages.
Calculation: 210 / 3 = 70 kg.
Explanation:
Step 2: Given the number of cars is 10, so 2x = 10. Therefore, x = 5.
Calculation: Number of bikes = 5x = 5 × 5 = 25.
Explanation:
Calculation: Speed = 360 / 6 = 60 km/h.
Explanation:
Calculation: Speed = 400 / 20 = 20 m/s.
Explanation:
Step 2: 2400 = CP × (1 + 20/100) = CP × (120/100) = CP × 1.2.
Calculation: CP = 2400 / 1.2 = 2000.
Explanation:
Step 2: Perform multiplication: 10 × 3 = 30.
Calculation: Perform addition: 36 + 30 = 66.
Explanation: The sentence describes a completed action in the past. Therefore, the simple past tense of the verb "blow" is required, which is "blew".
Explanation: In English grammar, when referring to the shadow cast by an object (like a tree), we use the preposition "in" (e.g., in the shade). We use "under" for the physical object itself (e.g., under the tree).
Explanation: The word "great" begins with a consonant sound (/g/). Therefore, the indefinite article "a" is appropriate.
Explanation: A "collision" involves two or more objects striking each other violently. "Crash" is the most direct synonym in the context of road accidents.
Explanation: "Accelerate" means to increase speed. Its direct antonym is "Decelerate", which means to reduce speed.
Explanation: "The two buses" is a plural subject. Subject-verb agreement rules dictate that a plural subject must take a plural verb. Therefore, "was" must be corrected to "were".
Explanation: A slip road (or exit ramp) is a short road giving access to, or an exit from, a motorway or dual carriageway.
Explanation: A "Yield" sign indicates that a driver must slow down, or stop if necessary, and give the right-of-way (give way) to vehicles approaching from other directions.
Explanation: "All four tyres" is a plural subject, and "last week" indicates a completed action in the past. Therefore, the plural past tense verb "were" is correct for this passive voice construction.
Explanation: The preposition "until" is used to indicate the point in time up to which an action (waiting) continues. It perfectly connects the ongoing action to the triggering event (the light turning green).
Explanation: "Heavy" begins with a consonant sound (/h/). The indefinite article "a" is used to refer to a non-specific singular countable noun (a heavy transport truck).
Explanation: "Fatigue" is extreme tiredness resulting from mental or physical exertion. "Exhaustion" is its closest synonym.
Explanation: "Hazardous" means risky, dangerous, or full of peril. Its direct antonym is "Safe", indicating freedom from danger.
Explanation: "He" is a third-person singular subject. In the present tense, third-person singular subjects must take "does not" (doesn't), not "do not" (don't).
Explanation: In traffic terminology, an intersection or junction is a point where two or more roads cross or meet, typically requiring traffic control measures.
Explanation: A breathalyzer is an electronic device used by police to estimate a driver's Blood Alcohol Concentration (BAC) from a breath sample, to determine if they are driving under the influence.
Explanation: This is a First Conditional sentence, describing a possible future event. The structure is "If + Simple Present, Subject + will + base verb". Thus, "will" is the correct modal.
Explanation: We use the preposition "on" when referring to a surface or a line, such as a road, street, or highway (e.g., driving on the road).
Explanation: "Horrific" starts with a consonant sound (/h/). The indefinite article "a" is appropriately used before it.
Explanation: "Drowsy" means feeling lethargic, half-asleep, or struggling to stay awake. "Sleepy" is the perfect synonym.
Explanation: "Strict" means demanding that rules concerning behavior are obeyed and observed. Its antonym is "Lenient", which means more merciful, tolerant, or relaxed in enforcing rules.
Explanation: "She" is a third-person singular subject. The simple present tense verb must take an 's' or 'es' ending. Therefore, "drive" must be "drives".
Explanation: A median strip or traffic divider is the reserved area that separates opposing lanes of traffic on divided roadways, such as dual carriageways or motorways.
Explanation: A blind corner is a bend or corner in a road where a driver's line of sight is obstructed by buildings, trees, or the road's curvature, preventing them from seeing what is approaching.
Explanation: The sentence describes an ongoing action starting in the past and continuing into the present ("for over five years"). This requires the Present Perfect Continuous tense: "have + been + verb-ing".
Explanation: "Keep your eyes on the road" is a standard idiomatic expression in driving. The preposition "on" correctly indicates the focus of attention upon the surface/path.
Explanation: The phrase refers to a single, non-specific instance of a fine. "Heavy" begins with a consonant sound, necessitating the article "a".
Explanation: An "infraction" is a minor offense or a failure to observe a rule or law, especially in traffic. "Violation" is the most accurate synonym.
Explanation: "Dense traffic" means heavily congested, slow-moving traffic with many vehicles closely packed. The opposite condition is "Light traffic", where vehicles are sparse and moving freely.
Explanation: "Must" is a modal auxiliary verb. Modals are always followed directly by the base form of a verb (bare infinitive), without the particle "to". So, "must stop" is correct; "must to stop" is an error.
Explanation: Mandatory road signs are generally circular with a blue background and white symbols. An arrow pointing left strictly commands the driver to "Compulsory Turn Left" or "Keep Left" as per the road layout.
Explanation: A solid red circle with a horizontal white bar across the middle is the universally recognized regulatory traffic sign for "No Entry", prohibiting vehicular traffic from proceeding past the sign.
Explanation: Object or hazard markers consist of alternating yellow and black diagonal stripes. They are placed to warn drivers of physical obstructions within or adjacent to the roadway, such as bridge piers, medians, or sharp curves.
Explanation: A continuous solid white line on the extreme edge of a highway is an "edge line". It delineates the edge of the carriageway, separating the driving lanes from the shoulder, and drivers are prohibited from crossing it unless in an emergency.
Explanation: Under the amended Motor Vehicles Act, 2019, jumping a red light is classified as dangerous driving. The penalty has been significantly increased to range between Rs 1,000 to Rs 5,000, along with potential suspension of the driving license.
Explanation: Section 192 of the Motor Vehicles Act stipulates that driving an unregistered motor vehicle on public roads is a serious offense, punishable with a fine of Rs 5,000 for the first offense.
Explanation: In India, self-drive rental cars (commercial vehicles leased for self-driving) are legally required to display a number plate with a black background and yellow lettering.
Explanation: Under the Motor Vehicles (Driving) Regulations, using a handheld mobile phone to make calls or text while driving is strictly illegal. The only exception is using the device strictly for route navigation, provided it is mounted safely and does not distract the driver.
Explanation: Section 134 of the Motor Vehicles Act explicitly mandates that if a driver is involved in an accident resulting in injury, their primary legal duty is to take all reasonable steps to secure medical attention for the injured person and report the accident to the nearest police station within 24 hours.
Explanation: While the suspension springs absorb the impact of bumps, they will continue to bounce (oscillate). The shock absorber's mechanical purpose is to dampen or control this bounce, ensuring the tyre remains in constant contact with the road for safe steering and braking.
Explanation: When a vehicle takes a turn, the outside wheel travels a longer distance than the inside wheel. The differential is a gear mechanism in the drivetrain that splits engine torque and allows these wheels to rotate at different speeds, preventing tyre scrubbing and axle stress.
Explanation: Normal tap water contains minerals and ions (like calcium and iron) that will react with the sulfuric acid in a lead-acid battery, coating the lead plates and drastically shortening the battery's life. Distilled water is pure H2O and prevents this internal damage.
Explanation: The standard operating cycle of a 4-stroke engine follows this sequence: 1. Intake (draws fuel/air), 2. Compression (compresses the mixture), 3. Power/Combustion (spark plug ignites mixture, forcing piston down), 4. Exhaust (expels burnt gases).
Explanation: Hydroplaning occurs when water on the road accumulates in front of the vehicle's tyres faster than their treads can displace it. The tyre is pushed up onto a thin layer of water, completely losing contact with the road and resulting in a total loss of steering and braking control.
Explanation: While they provide comfort, headrests (or head restraints) are primarily critical safety devices. In a rear-end collision, the body is thrown forward, but the head snaps backward violently. A properly adjusted headrest catches the head, preventing severe whiplash injuries to the cervical spine.
Explanation: Engine braking is a technique, particularly useful on long downhill descents, where a driver shifts to a lower gear. The internal resistance (compression) of the engine slows the vehicle's momentum naturally, preventing the main wheel brakes from overheating and failing.
Explanation: Fog lights project a wide, low, and extremely bright beam designed to cut beneath fog or heavy rain to illuminate the immediate road surface. Using them in clear conditions is illegal and dangerous as their intense brightness dazzles oncoming drivers.
Explanation: In the event of a high-speed blowout, the vehicle will pull violently to one side. Slamming the brakes causes an abrupt shift in weight and will instantly throw the car into an uncontrollable spin. The driver should firmly grip the wheel, ease off the accelerator, and brake gently only after gaining control.
Explanation: Tailgating means driving too closely behind the vehicle in front. Human reaction time combined with mechanical braking time dictates a minimum safe stopping distance. Tailgating eliminates this distance, making a severe rear-end collision virtually unavoidable if the leading vehicle stops abruptly.
Explanation: At an unmanned or unguarded railway crossing, the absolute legal and life-saving duty of a driver is to bring the vehicle to a complete halt, look in both directions, and listen carefully for train horns before proceeding across the tracks.
