Walking at 3/4 of his usual speed, a man reaches his office 20 minutes late. What is his usual time to reach the office?
सही उत्तर: ग) 60 minutes
At 3/4 speed time becomes 4/3 of usual; the extra 1/3 of usual time = 20 min, so usual time = 60 min.

A man rows to a place 48 km away and back in 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against it. What is the speed of the stream?
सही उत्तर: क) 1 km/h
Let downstream = 4k, upstream = 3k: 48/4k + 48/3k = 14 gives k = 2, so speeds are 8 and 6 km/h; stream = (8 - 6)/2 = 1 km/h.

A boat goes downstream at 20 km/h and upstream at 12 km/h. What is the speed of the boat in still water?
सही उत्तर: घ) 16 km/h
Speed in still water = (downstream + upstream)/2 = (20 + 12)/2 = 16 km/h.

In a 100 m race, A beats B by 10 m and B beats C by 10 m. By how many metres does A beat C?
सही उत्तर: ग) 19 m
When A runs 100 m, B runs 90 m; C runs 90 m for every 100 m of B, so C covers 90 x 0.9 = 81 m. A beats C by 19 m.

A train 150 m long passes a man running at 6 km/h in the same direction as the train in 9 seconds. What is the speed of the train?
सही उत्तर: घ) 66 km/h
Relative speed = 150/9 m/s = 60 km/h; train speed = 60 + 6 = 66 km/h.

Two trains 140 m and 160 m long run in the same direction at 60 km/h and 42 km/h. How long will the faster train take to pass the slower one completely?
सही उत्तर: ग) 60 seconds
Relative speed = 18 km/h = 5 m/s; distance = 140 + 160 = 300 m; time = 300/5 = 60 s.

A man walks at 5 km/h for 6 hours and then cycles at 15 km/h for 4 hours. What is his average speed for the whole journey?
सही उत्तर: क) 9 km/h
Distance = 30 + 60 = 90 km in 10 hours, so average speed = 9 km/h.

A is 50% more efficient than B. If B alone can do a work in 30 days, in how many days can A alone do it?
सही उत्तर: घ) 20 days
A does 1.5 times B's daily work, so A takes 30 / 1.5 = 20 days.

A pipe can fill a tank in 8 hours, but because of a leak it takes 10 hours. In how many hours can the leak alone empty the full tank?
सही उत्तर: क) 40 hours
Leak rate = 1/8 - 1/10 = 1/40 per hour, so the leak empties the tank in 40 hours.

-
Pipe A can fill a tank in 6 hours and pipe B in 8 hours. Both are opened together, and B is closed after 2 hours. How much longer will A take to fill the tank?
सही उत्तर: क) 2 1/2 hours
In 2 hours both fill 2(1/6 + 1/8) = 7/12; the remaining 5/12 takes A 5/12 x 6 = 2.5 hours.
