Dear Students,

Quantitative-Aptitude-Questions-for-IBPS-RRBs-PO-Exam-2017

Today we have been including some Boat and Stream.This is the Boat and Stream quiz and you should try to do it within 13-14 Mins. If you fail to complete it in stipulated time, then try again with full force. These quantitative aptitude questions are very important from exam point of view like IBPS RRB Exam, IBPS PO and IBPS Clerk.

Q1. A boat covers 48 km in upstream and 72 km in downstream in 12 hours, while it covers 72 km in upstream and 48 km in downstream in 13 hours. Find the speed of the stream
(a) 2km/h
(b) 4km/h
(c) 3km/h
(d) 5km/h
(e) 6km/h

Q2. A motor boat takes 12 hours to go downstream and it takes 24 hours to return the same distance. Find the ratio of the speed of the boat in still water to the speed of the stream.
(a) 2:3
(b) 3:1
(c) 3:4
(d) 3:2
(e) 1:3

Q3. P, Q and R are the three towns on the bank of a river which flows uniformly. Q is equidistant from P and R. I row from P to Q and back in 10 hours and I can row from P to R in 4 hours. Compare the speed of my boat in still water with that of the river.
(a) 4 : 3
(b) 5 : 3
(c) 6: 5
(d) 7 : 3
(e) 3:5

Q4. A boatman rows to a place 45 km distant and back in 20 hours. He finds that he can row 12 km with the stream in the same time as 4 km against the stream. Find the speed of the stream.
(a) 3 km/hr
(b) 2.5 km/hr
(c) 4 km/hr
(d) 5 km/hr
(e) 3.5 km/hr

Q5. A man who can swim 48 m/min in still water swims 200 m against the current and 200 m with the current. If the difference between those two times is 10 minutes, find the speed of the current.
(a) 30 m/min
(b) 29 m/min
(c) 31 m/min
(d) 32 m/min
(e) 28 m/min

Q6. A man can row 7 km/hr in still water. If the river is running at 3 km/hr, it takes 6 hours more in upstream than to go downstream for the same distance. How far is the place?
(a) 48 km
(b) 36 km
(c) 42 km
(d) 40 km
(e) None of these 

Q7. A man can cross a downstream river by steamer in 40 minutes and same by boat in 1 hour. If the time of crossing the river in the upstream direction by steamer is 50% more than downstream time by the steamer and the time required by boat to cross the same river by boat in upstream is 50% more than the time required in downstream by boat. What is the time taken for the man to cross the river downstream by steamer and then return to the same place by boat half the way and by steamer the rest of the way?
(a) 85 min
(b) 115 min
(c) 120 min
(d) 125 min
(e) 110 min

Q8. If a boat takes 4 hours to cover a distance of 8 km upstream while the speed of the stream is 1.5 km/hr. What is the speed of the boat in still water?
(a) 4 km/hr
(b) 6.5 km/hr
(c) 3.5 km/hr
(d) 2.5 km/hr
(e) None of these

Q9. A boat travels upstream from Q to P and downstream from P to Q in 3 hours. If the distance between P to Q is 4 km and the speed of the stream is 1 km/hr then what is the speed of the boat in still water?
(a) 4.5 km/hr
(b) 5.2 km/hr
(c) 2.5 km/hr
(d) 3 km/hr
(e) None of these

Q10. A boat travels upstream from P to Q and downstream from Q to Pin 3 hours. If the speed of the boat in still water is 9 km/hr and the velocity of the stream is 3 km/hr, then what is the distance from P to Q?
(a) 14 km
(b) 8 km
(c) 12 km
(d) 6 km
(e) None of these

Q11. A man can row 5 km/hr in still water and the velocity of the stream is 1.5 km/hr. He takes an hour when he travels upstream to a place and back again to the starting point. How far is the place from the starting point?
(a) 2.5 km
(b) 6.5 km
(c) 3.5 km
(d) 2.275 km
(e) None of these

Q12. A man can row 28/3 km/hr in still water and he finds that it takes him thrice as much time to row upstream as to row downstream (same distance). The speed of the current is -
Q13. A boatman can row a certain distance down the stream in 2 hours and up the stream the same distance in 3 hours. If the stream flows at the rate of 4 km/hr, what is the speed of the boat in still water?
