  • 250m

  • 240m

  • 260m

Q 10.

If two trains of equal length 120m takes 10 sec and 15 sec to cross a woman standing on the platform respectively. Then, how long will it take the trains to cross each other if they are travelling in opposite direction.

  • 14 s

  • 15 s

  • 12 s

  • 13 s

Q 11.

Two trains A and B are running at 40 kph and 20 kph respectively. If the faster train completely passes a man sitting in the slower train in 5 seconds then what is the length of the faster train.

  • 26 7   m
    9
  • 27 7   m
    9
  • 28 7   m
    9
  • 25 7   m
    9
Q 12.

Train A and B are running in opposite direction and approaching a station. If they cross a man standing on the platform in 27 sec and 17 sec respectively and they cross each other in 23 sec. Find the ratio of their speeds.

  • 3:2

  • 2:1

  • 4:5

  • 3:5

Let ratio of their speed be x:y

Length of A = 27x

Length of B = 17y

so, (27x + 17y) / (x + y) = 23

or, x/y = 3/2
