A train 200 m long running at 72 km/h crosses a platform 300 m long. How much time does it take?
सही उत्तर: घ) 25 seconds
72 km/h = 20 m/s. Distance = train + platform = 500 m, so time = 500/20 = 25 s. 10 s would ignore the platform.

A train 150 m long runs at 54 km/h. How long does it take to cross a telegraph pole?
सही उत्तर: ग) 10 seconds
54 km/h = 15 m/s. To pass a pole the train covers only its own length, so time = 150/15 = 10 s.

A man goes from A to B at 60 km/h and returns at 40 km/h. What is his average speed for the whole journey?
सही उत्तर: क) 48 km/h
For equal distances, the average speed = 2xy/(x + y) = 2 × 60 × 40/100 = 48 km/h. 50 km/h is the simple average, which is wrong because more time is spent at the slower speed.

A car covers 240 km in 4 hours. What is its speed in metres per second?
सही उत्तर: ख) 16.67 m/s
Speed = 60 km/h = 60 × 5/18 = 50/3 ≈ 16.67 m/s. To convert km/h to m/s, multiply by 5/18.

A is twice as efficient as B, and together they finish a work in 14 days. In how many days can A alone finish it?
सही उत्तर: ग) 21 days
Let B do x per day and A do 2x. Then 3x = 1/14, so x = 1/42 and A's rate is 1/21. A alone takes 21 days (B alone would take 42).

A pipe can fill a tank in 6 hours, but because of a leak at the bottom it takes 9 hours. In how many hours can the leak alone empty the full tank?
सही उत्तर: घ) 18 hours
Leak rate = 1/6 − 1/9 = 1/18 per hour, so the leak empties the tank in 18 hours.

Pipe A can fill a tank in 20 minutes and pipe B in 30 minutes. If both are opened together, how long will they take to fill the tank?
सही उत्तर: क) 12 minutes
Combined rate = 1/20 + 1/30 = 1/12 per minute, so the tank fills in 12 minutes. 25 minutes is just the average of the two times.

A and B together can finish a work in 8 days. A alone can finish it in 12 days. In how many days can B alone finish it?
सही उत्तर: क) 24 days
B's one-day work = 1/8 − 1/12 = 1/24, so B alone takes 24 days. 4 days comes from wrongly subtracting the days (12 − 8).

6 men can complete a work in 20 days. In how many days will 15 men complete the same work?
सही उत्तर: ख) 8 days
Total work = 6 × 20 = 120 man-days, and 120/15 = 8 days. More men means fewer days (inverse proportion).

A can do a work in 10 days and B in 15 days. They work together for 4 days, and then A finishes the remaining work alone. How many more days does A take?
सही उत्तर: ग) 3⅓ days
Together they do 1/10 + 1/15 = 1/6 per day, so in 4 days they finish 2/3. A does the remaining 1/3 in (1/3) × 10 = 10/3 = 3⅓ days.
