Quantitative Aptitude is a nerve-racking section especially in the main examination. The intense practice is required to balance Speed with respect to accuracy. The **IBPS PO Mains Study Plan 2019** consists of **quantitative aptitude quizzes** based on the latest pattern. Moreover, various shortcut tricks & tips have been provided in solutions by experts. Bankeradda will provide daily quizzes for practice as the** IBPS PO** Mains is scheduled for 30th November 2019. So practice to sail through IBPS PO Mains Exam.

**Q1. Speed of current is 10 km/hr and speed of a motor boat is 80% more than speed of current. Motor boat travels 280 km downstream with its usual speed, after that itâ€™s increased speed by â€˜sâ€™ kmph and travelled for another 280 km then it returns and covers 560 km in upstream. If boat complete whole journey downstream to upstream in 45 hr, then find the value of â€˜sâ€™?
**(a) 10 km/hr

(b) 8 km/hr

(c) 6 km/hr

(d) 12 km/hr

(e) 4 km/hr

**Q2. The ratio between length of two goods train is 5 : 4. If both trains running in same direction at the speed of 144 km/hr and 108 km/hr and faster train cross the slower train in 54 sec, then find in what time both goods train cross each other, when running in opposite direction?**

**Q3.** **Speeds of three motor boats A, B and C are equal and all cover 8 km of distance upstream in 48 minutes. Ratio between speed of motor boats and speed of stream is 6 : 1. On first day A starts in downstream from point P to Q, which shifts 9 km away from point P each day. On second day B starts from point P in downstream and reach at point Q in 4.5 hours, then find time take by C on third day to reach at point Q, (consider speed of stream same on all three days)?**

**Q4. Train A running at the speed of 108 km/hr crosses a man, who running in the opposite direction at the speed of 12 km/hr in 7.2 sec.

(b) 2 hours

(c) 3 hours

(d) 9 hours

**Q.7. A boat took 4 hours more to cover distance â€˜Dâ€™ in upstream than covering same distance in downstream and boat covers 98 km in downstream in 3.5 hours. Then, find the value of â€˜Dâ€™, if speed of stream is 8 km/hr.**

(a) 100 km

(b) 93 km

(c) 84 km

(d) 90 km

(e) None of the above.

**Q8. The ratio of time taken by boat A to boat B to swim a certain distance upstream and downstream respectively in a river is 7 : 4 respectively. The time taken by boat A to cover another distance in upstream is 75% more than the time taken by it to cover that distance in downstream. Find speed of boat B in still water is what percent of speed of boat A in still water?**

(a) 150%

(b) 120%

(c) 125%

(d) 80%

(e) 100%

**Q9. A man driving his car at 45 km/hr to reach his office on time, but had he driven his car 40% more speed then he would have reached his office 10 minutes earlier. Then, find the distance between his office and home**

(a) 25.40 km

(b) 26.25 km

(c) 25.85 km

(d) 26.90 km

(e) None of the above.

**Q10. Time taken by boat to cover 48 km in upstream is 200% of the time taken by boat to cover 48 km in downstream and sum of time taken by boat to cover above mentioned distance in upstream and in downstream is 9 hours. Then, find speed of boat.**

(a) 8 km/hr

(b) 10 km/hr

(c) 12 km/hr

(d) 4 km/hr

(e) 6 km/hr
