Questions and Answers

Q 1 - A train with a speed of 60 kmph crosses a pole in 30 seconds. The length of the train is

A - 500 m

B - 750 m

C - 900 m

D - 1000 m

Answer : A

Explanation

speed =  (60*5/18)m/sec  = 50/3 m/sec.
Length of the train = (50/3* 30)m = 500 m 

Q 2 - A 130 m long train crosses a bridge 30 seconds at 45 kmph. The length of the bridge is ?

A - 200 m

B - 225 m

C - 245 m

D - 250 m

Answer : C

Explanation

Let the length  of the bridge be x m.
Speed of the train = (130+x)/30 m/sec.
But, speed =(45*5/18)m/sec. =25/2 m/sec.
⇒ (130+x)/30 = 25/2 
⇒ 130 + x = 375
∴ x = 245 m

Q 3 - Two trains 105m and 90m long run at the speeds of 45kmph and 72 kmph respectively in opposite directions on parallel tracks. The time which they take to cross the each other, is

A - 5 sec

B - 6 sec

C - 7 sec

D - 8 sec

Answer : B

Explanation

Sum of the lengths of the train =(105+90)m=  195 m
 Relative speed = (72+45) kmph = 117 kmph = (117*5/18)m/sec. =585/18 m/sec.
Required time =  (195*18/585 ) sec.= 6 sec.

Q 4 - Two trains are running in opposite directions at 36kmph and 45kmph cross each other in 20 sec. if one train is 200m long, the length of the other train is

A - 144 m

B - 200 m

C - 240 m

D - 250 m

Answer : D

Explanation

let the length of the other train be x meters.
Sum of their length =(200+x)m
Relative speed =(36+45) kmph =81kmph = (81*5/18)m/sec. = 45/2 m/sec.
(200+x)/ (45/2) = 20  ⇒ 400 +2x = 900 ⇒ 2x = 500  ⇒ x = 250
∴  length of the other train is 250m 

Q 5 - Two trains running in the same direction at 40 km/hr and 22 km/hr completely pass one another in 1 minute. If the length of the first train is 125 m, the length of the second train is

A - 125 m

B - 150 m

C - 175 m

D - 200 m

Answer : C

Explanation

Relative speed =  (40-22)k/hr = 18km/hr =(18*5/18)m/sec.=5m/sec.
Let the length of the second train be x meters. then,
(125+x)/5= 60 ⇒ 125+x=300 ⇒ x =175m

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
