Dear Aspirants,
Q1. A boat takes 12 hours to cover an upstream distance of 48 km and 6 hours to come back same distance in downstream. What is the speed of boat in steel water?
Q2. A swimmer can swim 33⅓% faster in downstream than in upstream. He takes 4 hours to swim a distance of 32 km in still water. Speed of stream is how much percent of upstream speed?
Q3. Rohit and Mohit are coming via boat towards each other from the two banks of a river. They meet after three hours from start. If speed of both boats in still water is 6 kmph and river is flowing from Mohit towards Rohit, then find the distance between two banks.
Q4. A motorboat, whose speed in 15 km/hr in still water goes 30 km downstream and comes back in a total of 4 hours 30 minutes. The speed of the stream (in km/hr) is
Q5. A boat running upstream takes 8 hours 48 minutes to cover a certain distance, while it takes 4 hours to cover the same distance running downstream. What is the ratio between the speed of the boat in still water and speed of the water current respectively?
Q6. A boat takes 9hr to travel a distance upstream and takes 6hr to travel the same distance downstream. If the speed of the boat in still water is 4 kmph, then what is the velocity of the stream?
Q7. A boat has to travel upstream 20 km distance from point X of a river to point Y. The total time taken by boat in travelling from point X to Y and Y to X is 41 min 40 s. What is the speed of the boat?
Q8. A steamer goes downstream from one port to another in 4 hr. It covers the same distance upstream in 5 hr. If the speed of the stream is 2 kmph, then find the distance between the two ports.
Q9. The ratio of speeds of a motorboat to that of the current of water is 36 : 5. The motorboat goes along with the current in 5 hours 10 min. Find the time taken by motorboat to come back.
Q10. Kamal can row a certain distance downstream in 12 hours and can return the same distance in 18 hours. If the stream flows at the rate of 6 kmph, then find the speed of Kamal in still water.

Quantitative Aptitude Quiz For SBI PO/Clerk Prelims
Numerical Ability or Quantitative Aptitude Section has given heebie-jeebies to the aspirants when they appear for a banking examination. As the level of every other section is only getting complex and convoluted, there is no doubt that this section, too, makes your blood run cold. The questions asked in this section are calculative and very time-consuming. But once dealt with proper strategy, speed, and accuracy, this section can get you the maximum marks in the examination. Following is the Quantitative Aptitude quiz to help you practice with the best of latest pattern questions.
Q1. A boat takes 12 hours to cover an upstream distance of 48 km and 6 hours to come back same distance in downstream. What is the speed of boat in steel water?
6 kmph
4 kmph
8 kmph
12 kmph
10 kmph
Solution:
Q2. A swimmer can swim 33⅓% faster in downstream than in upstream. He takes 4 hours to swim a distance of 32 km in still water. Speed of stream is how much percent of upstream speed?
16.33%
12.25%
none of these.
16.67%
14.28%
Solution:
Q3. Rohit and Mohit are coming via boat towards each other from the two banks of a river. They meet after three hours from start. If speed of both boats in still water is 6 kmph and river is flowing from Mohit towards Rohit, then find the distance between two banks.
48 km
24 km
36 km
18 km
None of these
Solution:
Q4. A motorboat, whose speed in 15 km/hr in still water goes 30 km downstream and comes back in a total of 4 hours 30 minutes. The speed of the stream (in km/hr) is
2 km/hr
3 km/hr
4 km/hr
5 km/hr
6 km/h
Solution:
Q5. A boat running upstream takes 8 hours 48 minutes to cover a certain distance, while it takes 4 hours to cover the same distance running downstream. What is the ratio between the speed of the boat in still water and speed of the water current respectively?
2 : 1
3 : 2
8 : 3
Cannot be determined
4:5
Solution:
Let the man's rate in upstream be x kmph and in downstream be y kmph.
Then, distance covered upstream in 8 hrs 48 min = Distance covered downstream in 4 hrs.
Then, distance covered upstream in 8 hrs 48 min = Distance covered downstream in 4 hrs.
Q6. A boat takes 9hr to travel a distance upstream and takes 6hr to travel the same distance downstream. If the speed of the boat in still water is 4 kmph, then what is the velocity of the stream?
1 kmph
2 kmph
1.5 kmph
0.8 kmph
0.5 kmph
Solution:
Q7. A boat has to travel upstream 20 km distance from point X of a river to point Y. The total time taken by boat in travelling from point X to Y and Y to X is 41 min 40 s. What is the speed of the boat?
66 kmph
72 kmph
48 kmph
Cannot be determined
75 kmph
Solution:
Q8. A steamer goes downstream from one port to another in 4 hr. It covers the same distance upstream in 5 hr. If the speed of the stream is 2 kmph, then find the distance between the two ports.
80 km
60 km
70 km
50 km
75 km
Solution:
