1.

A train of length 200 m can cross a man, sitting inside another train of length 100 m coming from opposite direction at speed of 25 m/sec, in 5 seconds. Find the speed of first train?

   A.) 40 m/sec
   B.) 20 m/sec
   C.) 10 m/sec
   D.) 35 m/sec

Answer: Option 'D'

Time taken by the train to cross the man = 300/(x+25) = 5 or 'x' = 35 m/sec

2.

A train 360 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 140 m long? 

   A.) 40 seconds
   B.) 45 seconds
   C.) 42 seconds
   D.) 48 seconds

Answer: Option 'A'

Given, Length of train =360 m
Length of bridge =140 m
Speed of train = 45 km/hr ---> Converting into meter/ second
= 45 × (5/18) m / sec
= 12.5 m/sec
=>Speed of train = 12.5 m/sec
Required Time =(Length of train +Length of bridge) /Speed of train
= (360 + 140) / 12.5
= 500 / 12.5
= 40 sec
=>Required Time =40 sec

3.

The 200-metre train crosses a platform double its length in 36seconds. What is the speed of the train in km/hr?

   A.) 60
   B.) 48
   C.) 64
   D.) 66

Answer: Option 'A'

Speed of the train = (200 + 400)m/36 sec = 600/36 m/sec
= (600*18)/(36*5) km/h 
= 60 km/h

4.

If a man walks 24 Km at 8 Kmph, he will be late by 25min. if he walks 12 Kmph, how early the fixed time Will he reach? 

   A.) 30 minutes
   B.) 25 minutes
   C.) 40 minutes
   D.) 35 minutes

Answer: Option 'D'

Time taken to cover 24 Km at the speed of 8 Kmph = 24/8 = 3 hours 
Thus, right time was 2 hours 35 mintes 
Now, time taken to cover 20 Km at the speed as 12 Kmph = 2 hours 
Required time = 2 hours 35 minutes - 2 hours 
= 35 minutes

5.

A train moves past a telegraph post and a bridge 264 m long in 8 seconds and 20 seconds respectively. What is the speed of the train?

   A.) 76 km/hr
   B.) 79.2 km/hr
   C.) 69.5 km/hr
   D.) 68.5 km/hr

Answer: Option 'B'

79.2 km/hr
