Two trains of equal length cross a pole in 10 seconds and 20 seconds respectively. If the length of each train is 100 meters, find the time taken by them to pass each other when running in opposite directions.
A. 12.24 seconds
B. 15.00 seconds
C. 13.33 seconds
D. 14.50 seconds
Answer: Option C
Solution (By JKSSB Mock Tests)
Speed of first train = 100 / 10 = 10 m/s. Speed of second train = 100 / 20 = 5 m/s. Total distance to cross = 100 + 100 = 200 meters. Relative speed in opposite directions = 10 + 5 = 15 m/s. Time taken = 200 / 15 = 13.33 seconds.
