Quantitative Apitude-Problems on Boat & Stream
Quantitative Apitude-Problems on Boat & Stream
1. If a man swim downstream at 6 kmph and upstream at 2 kmph. his speed in still water is :
- 4 km/hr
- 2 km/hr
- 3 km/hr
- 2.5 km/hr
2. A man can row upstream at 8 kmph and downstream at 13 kmph. The speed of the stream is :
- 5 km/hr
- 2.5 km/hr
- 10.5 km/hr
- 4.2 km/hr
3. If Anshul rows 15 km upstream and 21 km downstream taking 3 hours each time, then the speed of the stream is :
- 1 km/hr
- 1.5 km/hr
- 2 km/hr
- 12 km/hr
4. A man rows 13 km upstream in 5 hours and also 28 km downstream in 5 hours. The velocity of the stream is :
- 1.5 km/hr
- 2 km/hr
- 2.5 km/hr
- 3 km/hr
5. If a boat goes 7 km upstream in 42 minutes and the speed of the stream is 3 kmph, then the speed of the boat in still water is :
- 4.2 km/hr
- 9 km /hr
- 13 km/hr
- 21 km/hr
6. A manc an row a boat at 10 kmph in still water. If the speed of the stream is 6 kmph, the time taken to row a distance of 80 km down the strea is :
- 8 hours
- 5 hourrs
- 10 hours
- 20 hours
7. A boat takes 4 hours for travelling downstream from point A to point B and coming back to point A upstream. If the velocity of the stream is 2 kmph and the speed of the boat in still water is 4 kmph, what is the distance between A and B ?
- 4 kms
- 6 km
- 8 km
- 9 km
8. If a man rows at 6 kmph in still water and 4.5 kmph against the current, then this rate along the current is ;
- 9.5 km/hr
- 7.5 km/hr
- 7 km/hr
- 5.25 km/hr
9. If a man's rate with the current is 11 kmph and the rate f the current is 1.5 kmph, then the man's rate against the current is :
- 8 km/hr
- 9.5 km/hr
- 9 km/hr
- 6.25 km/hr
10. Speed of a boat in standing water is 9 kmph and the speed of the stream is 1.5 kmph. A man rows to a place at a distance of 10.5 km and comes back to the starting point. the total time taken by his is :
- 16 hours
- 18 hours
- 20 hours
- 24 hours
