**Q1.The speed of car is 25% more than the speed of bus. The time difference between them to cover a certain distance D, is 1 hour. On particular day, driver noticed that if they are (D- 40) km apart from each other then they can meet in 2 hours driving in opposite direction at their normal speed. Find 150% of the speed of bus ? **

(a) 150 km/hr

(b) 90 km/hr

(c) 120 km/hr

(d) 105 km/hr

(e) None of these

**Q2. Abhishek and Ayush start travelling in same direction at 8 km/hr and 13 km/hr respectively. After 4 hours, Abhishek doubled his speed and Ayush reduced his speed by 1 km/hr and reached the destination together. How long the entire journey last ? **

(a) 9 hr

(b) 8 hr

(c) 4 hr

(d) 7 hr

(e) 6 hr

**Q3. Two points A and B are 150 km are apart. Kunal leaves point A towards point B by bike at uniform speed of 50 kmph. After one hour, Hemant leaves point B towards point A by car at a uniform speed of 60 kmph. Each of them stops at a point 15 km from their starting point for 12 minutes. Find the distance between point A and the point where they meet?**

1200/11 km

1050/11 km

1350/11 km

850/11 km

1450/11 km

**Q4. A car covered 48 km less in T hours than a train, if speed of train is 25% more than speed of car, which is 64 km/hr and speed of an aircraft is 62½ % more than the sum of speed of car and train. Find how much distance will be covered by aircraft in (T – ¼) hour? **

(a) 634.5 km

(b) 624.5 km

(c) 643.5 km

(d) 648.5 km

(e) 664.5 km

**Q7. 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 it’s increased speed by ‘s’ 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 ‘s’?**

(a) 10 km/hr

(b) 8 km/hr

(c) 6 km/hr

(d) 12 km/hr

(e) 4 km/hr

**Q8. Speed of a boat in still water is 20 km/hr and speed of current is 4 km/hr, if time taken by boat to cover a distance of (d – 40) km upstream is one hour more than the time taken by boat to cover a distance of (d – 24) km in downstream, then find time taken by boat to cover a distance of (d + 48) km in downstream and in upstream both?**

(a) 16.5 hours

(b) 17 hours

(c) 18 hours

(d) 17.5 hours

(e) 18.5 hours

**Directions (9– 10):- Ratio of upstream and downstream speed of a boat (A) is 7 : 11 and boat cover 70 km upstream in 5 hours. Boat (B) takes 10 hours to cover 120 km in upstream. (speed of stream is same for both boat)**

**Q10.If speed of boat C in still water is 25% more than that of speed of boat B in still water, then find ratio of speed of boat A to speed of boat C in still water?**

(a) 7 : 10

(b) 9 : 11

(c) 9 : 8

(d) 8 : 9

(e) 9 : 10
