Quantitative Aptitude Quiz For IBPS PO/Clerk Prelims
Q1. A boat running downstream covers a distance of 16 km in 2 hours while for covering the same distance in upstream, it takes 4 hours. What is the speed of the boat in still water?
Q2. The speed of boat with the current is 15 kmph and the speed of the current is 2.5 kmph. The speed of boat against the current is:
Q3. A man can row a boat at 5 kmph in still water. If the velocity of current is 1 kmph and it takes him 1 hour to row to a place and come back, how far is the place?
Q4. A man can row a boat against the current three fourth of a kilometer in 15 min and returns same distance in 10 min, then ratio of his speed in still water to that of current is:
Q5. If the speed of a swimmer in still water is 9 kmph. Find the downstream speed of the swimmer, when the river is flowing with the speed of 6 kmph.
Q6. A man can row a boat 6 kmph in still water. If the speed of the current is 2 kmph, it takes 3 hours more in upstream than in the downstream for the same distance. The distance is:
Q7. 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?
Q8. 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?
Q9. A swimmer 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.
Q10. 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 in still water and speed of the current respectively?
Q11. The ratio of speeds of a motorboat in still water to that of the speed of current is 36 : 5. The motorboat goes along with the current in 5 hours 10 min. Find the time taken by motorboat to come back.
Q12. Akhlakh is rowing a boat. He takes half time in moving a certain distance downstream than upstream. What is the ratio of the rate of boat in still water to the rate of current?
Q13. Keshav 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 Keshav in still water.
Q14. A boatman rows 1 km in 5 min along the stream and 6 km in 1 hours against the stream. The speed of the stream is:
Q15. Simran can row a boat a certain distance downstream in 24 hours and can come back covering the same distance in 36 hours. If the stream flows at the rate of 12 kmph, find the speed of Simran in still water.
