A tunnel of 600m length has two parallel rail tracks laid in it. Two trains of length 400 m and 200 m enter the tunnel simultaneously. After how much time from the instant the two train entered the tunnel, will the tunnel be free of traffic? (Given the speeds of the two trains, of length 400m and 200m are 72 km/hr and 36 km/hr respectively.)

Correct

Answer – 2) 80 seconds
Explanation
The 400 m long train would cross the tunnel in 600+400/72×5/18 = 50 seconds
The 200m long train would cross the tunnel in = 600 +200/36×5/18 = 80 seconds
Hence in 80 seconds i.e. the maximum of the times taken by trains to cross the tunnel, the tunnel would be free of traffic.

Incorrect

Answer – 2) 80 seconds
Explanation
The 400 m long train would cross the tunnel in 600+400/72×5/18 = 50 seconds
The 200m long train would cross the tunnel in = 600 +200/36×5/18 = 80 seconds
Hence in 80 seconds i.e. the maximum of the times taken by trains to cross the tunnel, the tunnel would be free of traffic.
