Quantitative Aptitude For IBPS Clerk Mains 2019

Quantitative Aptitude Practice Questions is Based on Boat and StreamNumerical Ability 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 Numerical Ability quiz to help you practice with the best of latest pattern questions.

Q1. The respective ratio between the speed of the boat upstream and speed of the boat downstream is 4: 9. What is the speed of the boat in still water if it covers 84 km downstream in 2 hours 20 minutes? (in km/h) (a) 24 (b) 26 (c) 22 (d) 28 (e) 30

Q2. A man can swim 48 m/min in still water, he swims 200 m against the current and 200 m with the current. If the difference between those two times is 10 min, what is the speed of the current? (a) 30 m/min (b) 31 m/min (c) 29 m/min (d) 32 m/min (e) 26 m/min

Q4. A man can row 14 km/hr in still water. If the river is running at 4 km/hr, it takes 4 hours more in upstream than to go downstream for the same distance. How far is the place? (a) 88 km (b) 96 km (c) 92 km (d) 90 km (e) 94 km

Q5. A boat running downstream covers a distance of 24 km in 3 hours while for covering the same distance upstream, it takes 4 hours. What is the speed of the boat in still water?  (a) 4 kmph (b) 7 kmph (c) 8 kmph (d)12 kmph (e)10 kmph

Q6. A man’s speed with the current is 15 kmph and the speed of the current is 2.5 kmph. The man’s speed against the current is:  (a) 8.5 kmph (b) 9 kmph (c) 10 kmph (d)12.5 kmph (e) 14 kmph

Q7. A man can row at 7 kmph in still water. If the velocity of current is 3 kmph and it takes him 7/2 hour to row to a place and come back, how far is the place?  (a) 10 km (b) 12 km (c) 13 km (d) 16 km (e) 14 km

Q8. A man can row against the current three fourth of a kilometer in 15 min and returns same distance in 10 min, then ratio of his speed to that of current is:  (a) 3 : 5 (b) 5 : 3 (c) 1 : 5 (d) 5 : 1 (e) 4 : 1

Q9. If the speed of a swimmer in still water is 8.5 kmph. Find the downstream speed of the swimmer, when the river is flowing with the speed of 4.5 kmph.  (a) 13 kmph (b) 15 kmph (c)  3 kmph (d) 12 kmph (e) 10 kmph

Q10. A man can row 8 kmph in still water. If the speed of the current is 4 kmph, it takes 2 hours more in upstream than in the downstream for the same distance. The distance is:  (a) 10 km (b) 12 km (c) 14 km (d) 16 km (e) 18 km

Q11. A boat takes 9 hr to travel a distance upstream and takes 3 hr 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?  (a) 4 kmph (b) 3 kmph (c) 6 kmph (d) 2 kmph (e) 8 kmph

Q12. 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?  (a) 66 kmph (b) 72 kmph (c) 48 kmph (d) Cannot be determined (e) None of these

Q13. A boatman 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.  (a) 80 km (b) 60 km (c) 70 km (d) 50 km (e) 75 km

Q14. A boat running upstream takes 528 min to cover a certain distance, while it takes 240 min to cover the same distance running downstream. What is the ratio between the speed of the boat and speed of the water current respectively?  (a) 2 : 1 (b) 3 : 2 (c) 8 : 3 (d) 3 : 8 (e) 5 : 9

Q15. Harish can row a certain distance upstream in 18 hours and downstream the same distance in 12 hours. If the stream flows at the rate of 6 kmph, then find the speed of Harish in still water.  (a) 30 kmph (b) 35 kmph (c) 28 kmph (d) 25 kmph (e) 22 kmph
