Quantitative Apitude-Problems on Boat & Stream
Quantitative Apitude-Problems on Boat & Stream
11. A boat moves upstream at the rate of 1 km in 10 minutes and downstream at the rate o 1 km in 6 minutes. The Speed of the current is :
- 1 km/hr
- 1.5 km/hr
- 2 km/hr
- 2.5 km/hr
12. River is running at 2 kmph. If takes a man twice as long to row up as to row down the river. the rate of the man in still water is :
- 6 km/hr
- 4 km/hr
- 10 km/hr
- 8 km/hr
13. A man rows to a place 48 km distant and back in 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against the stream. The rate of the stream is :
- 1 km/hr
- 1.8 km/hr
- 3.5 km/hr
- 1.5 km/hr
14. The current of stream runs at 1 kmph. a motor boat goes 35 km upstream and back again to the starting point in 12 hours. The speed of the motor boat in still water is :
- 6 km/hr
- 7 km/hr
- 8 km/hr
- 8.5 km/hr
15. The speed of a boat in still water is 15 km/hr and the rate of current is 3 km/hr. The distance travelled downstream in 12 minutes is :
- 3.6 km
- 2.4 km
- 1.2 km
- 1.8 km
16. A man can row 5 kmph in still water. If theriver is running at 1kmph, it takes him 75 minutes to row to a place and back. Hw far is the place ?
- 3 km
- 2.5 km
- 4 km
- 5 km
17. A man can row 5 kmph in still water. If the river is running at 1kmph, it takes him 75 minutes to row to a place and back. How far is the place ?
- 3 km
- 2.5 km
- 4 km
- 5 km
18. If a man rows a the rate of 5 kmph in still water and his rate against the current is 3.5 kmph, then the man's rate along the current is :
- 4.25 kmph
- 6 kmph
- 6.5 kmph
- 8.5 kmph
19. A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream.
- 2 hours
- 3 hours
- 4 hours
- 5 hours
20. A man's speed with the current is 15 km/hr and the speed of the current is 2.5 km/hr. The man's speed against the current is:
- 8.5 km/hr
- 9 km/hr
- 10 km/hr
- 12.5 km/hr
