Q 1 - A train 132m long passes a telegraph post in 6 seconds. The speed of the train is
Answer : C
Explanation
speed =(132/6)m/sec =22 m/sec. =(22*18/5) kmph = (396/5) = 79.2 kmph
Q 2 - How much time will a train 171 m long take to cross a bridge 229 m long , if it is running at a speed of 45 kmph?
Answer : C
Explanation
Speed = (45*5/18)m/sec = 25/2 m/sec. Required time =(171+229)/(25/2) sec. = (400*2/25)sec. =32 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
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
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
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 - Two trains are running at 40 km/hr and 20 km/hr respectively in the same direction. Fast train completely passes a man sitting in the slower train in 5 sec.What is the length of the faster train?
Answer : D
Explanation
Relative speed = (40-20)km/hr = 20km/hr =(20*5/18)m/sec. =50/9 m/sec. Length of faster train = distance travelled by it in 5 sec. at 50/9 m/sec. =(50/9*5)m = 250/9 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
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
