Question

Ratio between length of two trains is 1 : 2 and speed of two trains is 120
km/hr & 108 km/hr respectively
and both trains running in same direction cross each other in 108 sec. If two compartments were added in
smaller train then it can cross a platform of length of 12.5 times of length of one compartment in 14.04 sec,
then find the time taken by longer train to cross that same platform, iffive new compartments were added in
to that train?
1. 18 sec
2.22 sec

Answer 1

Answer:

We know that,

Fast train is 50km/h

And slow train is 30 km/h

Then,

The length of the faster train is

=(50−30)×

18

5

×18 {Cancel 18 by 18}

=100m

Then,

Option C is correct answer.
