Answer:
The ratio of lengths of two trains is 5 : 3 and the ratio of their speeds is 6 : 5. The ratio of time taken by them to cross a pole is
A) 5:6
B) 11:8
C) 25 :18
D) 27: 16
Correct Answer:
C) 25 :18
Description for Correct answer:
We know that,
When a train crosses a pole, i.e. it covers the distance equal to its length
Time taken by train A to cross the pole
=Total distanceSpeed=5x6y
Time taken by train B to cross the pole
=TotaldistanceSpeed=3x5y
A : B
Ratio of the their time
=5x6y:3x5y= 25 : 18
