SSC MTS 2022 PYQ — Question 54

The correct answer is option 3 i.e. 350 m.

Length of train = 200 m

Speed of train = 36 km/h

Time taken by train to cross the bridge = 55 sec

Distance = Speed × Time

Speed(in m/s) = Speed(in km/h) $\times {5 \over 18}$

The speed of the train in m/s = 36 $\times {5 \over 18}$ = 10 m/s

Let the length of the bridge = x

We know, Distance Travelled = Speed × Time

According to the given statement, 

⇒ 200 + x = 10 × 55

⇒ x = 550 - 200

⇒ 350 m
