A) 15 sec B) 12.5 sec C) 7.5 sec D) 8 sec E) 10 sec
Explanation: x = bike speed in km/h
Ans: C
2. Train A is running at a speed of 48 kmph and crosses a man who is running at 6 kmph in opposite direction in 12 seconds. Train A crosses Train Z, which is running at a speed of 30 kmph in the same direction in 1 minute. Find the length of train Z.
A) 100m B) 120m C) 150m D) 200m E) 240m
Explanation: Length of Train A
Ans: B
3. Two trains, longer train 420m, while the ratio of their speed is 5 : 4. Two trains crossed each other in 8 sec. approximately how many seconds the faster train will cross a platform half of its length. If the speed of the slower train is 152 km/hr and the long train travels at a slower?
A) 5 sec B) 10 sec C) 8 sec D) 12 sec E) 18 sec
Explanation: Train1 length = 420m,
Train1 speed = 152 km/h
Train2 length = x,
Train2 speed = 190 km/h
Ans: B]
4. 300 m long Train A crosses Train B of 180 m in length which is running in the opposite direction in 5 (5/11) sec. If the speed of train 11 B is 20% more than that of train A, then find the time taken by both trains to cross each other, when they are running in the same direction.
A) 75 sec B) 60 sec C) 108 sec D) 45 sec E) 30 sec
Explanation: Length of Train A = 300 m
Length of Train B = 180 m
Speed of Train A & B = 5x, 6x
Ans: B
5. Train B travelling at a speed of 108 km/h crosses Train A, having a length 40 meter more than Train B and travelling in opposite direction at a speed of 90 km/h in 16 seconds. If Train A crosses a bridge in 28 seconds, then find how much time Train B will take to cross the same bridge?
A) 28 sec B) 18 sec C) 22 sec D) 36 sec E) 45 sec
Explanation: Train A length = (x + 40)m
Train A speed = 90 km/h
Train B length = x m
Train B speed = 108 km/h
x + 40 = 880
2x = 840
x = 420
Train B length = 420m,
Train A length = 460m
Train A crosses a bridge in 28 sec
Ans: C
6. Train A and Train B cross each other in 15 seconds when running in the opposite direction, and Train A crosses Train B in 345/13 seconds when running in the same 13 direction. Length of Train B is 150% of the length of Train A and speed of Train B is 60 km/h. Find the speed of the train A in m/s.
A) 30 B) 75 C) 90 D) 45 E) 60
Explanation: Length of Train A = 2x
Length of Train B = 3x
Speed of Train B = 60 km/h
Speed of Train A = y
13y + 780 = 23y − 1380
10y = 2160
y = 216 km/h
Ans: D
7. Train A running at speed of 64 km/hr. crosses a pole in 27 seconds and train B crosses a man in 36 seconds. Ratio of speed of trains A to B is 8 : 7 and both trains running in the opposite direction to each other, cross each other in ........ sec?
A) 43.2 sec B) 28.8 sec C) 32.2 sec D) 25.6 sec E) 30 sec
Explanation: Length of Train A
Ans: C
8. Train A travelling at the speed of 45 km/h crosses a pole in 22 seconds. If the same train crosses a platform in 32 seconds, then find the time taken by train A to cross another stationary train B whose length is 80% more than the platform?
A) 30 sec B) 40 sec C) 60 sec D) 75 sec E) 80 sec
Explanation: Length of Train A
9. Speed of Train A and Train B is ‘S’ km/hr and ‘S + 6’ km/hr. Length of Train A is 60 meters less than Train B. While running in the same direction Train B overtakes Train A in 396 sec. Train A crosses a bridge double of its length in 108 sec. Find the time taken by Train B to cross the same bridge? (approximately)
A) 48s B) 84s C) 90s D) 96s E) 160s
Explanation: Speed of Train A = S km/h,
Length of Train A = x m
Speed of Train B = (S + 6) km/h,
Length of Train B = (x + 60)m
Length of Train A = 300 m
Length of Train B = 360 m
Bridge length = 2 × 300 = 600 m
Train A crosses a bridge in 108 sec
10. Two Trains A and B, which are ‘n’ km apart from each other start moving towards each other at the speed of 10 km/hr and 15 km/hr, respectively. In such a way that in first hour A moves and B does not move, in 2nd hour only B moves and A does not move and this continues till they meet. Find the value of n’, if they meet after 8 (1/2) hours
A) 210 km B) 100 km C) 200 km D) 105 km E) 110 km
