A train travelling at 36km/h crosses a pole in 25 second. How much time (in second) will it take to cross a bridge 350m long?

A) 72

B) 48

C) 60

D) 56

Detailed solution : {The above question had appeared in the CGL Mains 2020 }

Let the length of train = x

36×5/18 = x/25

x= 250

36×5/18 = 350+250/time (t)

time(t) = 60 second

ANSWER : c) 60
