Quantitative Aptitude ( CCS) Problems on trains

A train moving at a rate of 36 km/hr, crosses a standing man in 10 seconds. It will cross a platform 55 meters long, in

6 seconds

7 seconds

15 1/2 seconds

5 1/2 seconds

length of the train = S x T

36 km/hr x 10 sec = 36 x 5/18 x 10 = 100 mts

Time taken by train to cross a plateform of 55 metre long in time

= (100 + 55) /36 x 5/18 = 155/10

Time = 15 1/2 seconds

Hence, option 3 is the correct answer.
