(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)

Q9. Find total time taken by boat B to cover 80 km in downstream & same distance in upstream?

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

Q12. ‘X’ meters long train cross a pole in ‘t’ sec and a platform which is ‘L’ meters long in 20 sec. If speed of train is 72 km/hr, then what will be value of ‘t’ and ‘L’
(a) 16 & 140
(b) 12 & 200
(c) 8 & 240
(d) 8 & 200
(e) 16 & 120

Q13. Train ‘X’ takes 2 hours more than train ‘Y’ to cover certain distance ‘D’ while train ‘X’ can cover (D+160) is 8 hours. If speed of train ‘Y’ is 50% more than that of train ‘X’, then find the speed of train ‘Y’?
(a) 80 km/hr
(b) 120 km/hr
(c) 16 km/hr
(d) 40 km/hr
(e) 60 km/hr

(a) 18 sec
(b) 22 sec
(c) 16 sec
(d) 20 sec
(e) 28 sec
