Questions and Answers

Q 1 - The speed of a train 150 m long is 50 kmph. How much time will it take to pass a platform 600 m long ?

A - 50 sec

B - 54 sec

C - 60 sec

D - 64 sec

Answer : B

Explanation

Speed =(50*5/18) m/sec. =125/9 m/sec
Required time = (600+ 150)/ (125/9) sec.=(750*9/125)sec. =54 sec.

Q 2 - A train 100 m long crosses a bridge of length 100 m in 6 sec. The train will cross another bridge of length 200 m in:

A - 8 sec

B - 9 sec

C - 10 sec

D - 11 sec

Answer : B

Explanation

Time taken to cover (100+100)m= 6 sec
Speed of the train = 200/6  m/sec.
Time taken to cover (100+200)m = (300*6/200) sec =9 sec.

Q 3 - A train crosses a pole in 15 sec. while it crosses a 100m long platform in 25 sec. The length of the train is

A - 125 m

B - 135 m

C - 150 m

D - 175 m

Answer : C

Explanation

Let the length of the train be x metres. Then,
 x/15 =(100+x)/25  ⇒ 25x=1500+15x ⇒ 10x = 1500 ⇒ x = 150
Hence, the length  of the train is 150 m.

Q 4 - A train 100 m in length passes a milestone in 10 sec. and another train of the same length is going in opposite direction in 8 sec. The speed of the second train is

A - 36 kmph

B - 48 kmph

C - 54 kmph

D - 60 kmph

Answer : C

Explanation

Speed of the first train = (100/10)m/sec. =  10m/sec.
Let the speed of the second train be x m/sec.
200/ (10+x) = 8   ⇒ 8(10+x) =200 ⇒ 8x = 120 ⇒ x =15 
∴  speed of the second train =15m/sec. = (15*18/5) =54km/hr

Q 5 - A train of length 150m takes 10 sec. to pass over another train 100m long coming from the opposite direction. If the speed of the first train be 30 kmph, then the speed of the second train is

A - 54 kmph

B - 60 kmph

C - 72 kmph

D - 36 kmph

Answer : B

Explanation

Relative speed =(150+100)/10 m/sec.  =25 m/sec.= (25*18/5)km/hr = 90 km/hr 
∴ speed of the  second train = (90-30) kmph  = 60 kmph

Q 6 - A train is running at the rate of 40kmph. A man is going in the same direction parallel to the train at 25kmph . If the train crosses the man in 48 sec. , the length of the train is

A - 50 m

B - 100 m

C - 150 m

D - 200 m

Answer : D

Explanation

relative speed = (40-25)kmph =15kmph  =(15*5/18) m/sec. =25/6 m/sec.
Length of the train = (25/6*48)m= 200 m.

Q 7 - Two goods trains each 500m long, are running in opposite directions on parallel tracks. Their speeds are 45km/hr and 30km/hr respectively. The time taken by the slower train to pass the driver of the faster one is

A - 12 sec

B - 24 sec

C - 48 sec

D - 60 sec

Answer : C

Explanation

Relative speed = (45+30)km/hr =  75km/hr =(75*5/18)m/sec. = 125/6 m/sec.
Distance covered = (1500-500)= 1000m
Required time = (1000*6/25) sec.  =48 sec
