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

### 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 ?

### 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 - A train 100 m long moving at a speed of 50km/hr crosses a train 120m long coming from opposite side on parallel tracks in 6 sec. The speed of the second train is

### Answer : B

### Explanation

let the speed of the second train be x kmph. Their relative speed = (50+x) kmph ={ (50+x)* 5/18) m/sec. Sum of their lengths = (100+120)m =220 m 220/ [(50+x)*5/18] = 6 ⇒30 (50+x)= 3960 ⇒ 30x =(3960-1500) = 2460 X = 82 Speed of the second train = 82 kmph.

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 moving at the rate of 36 km per hour crosses a standing man in 10 sec. It will cross a platform 55m long, in

### Answer : D

### Explanation

speed of the train = (36*5/18)m/sec. =10m/sec. Let the length of the second train be x meters. Then, x/10 =10 ⇒ x =100m Time taken by the train to cross the platform = (100+55)/10 sec.=31/2 sec.

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

### 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 - A train X start from Meerut at 4 pm and reaches Ghaziabad at 5p.m while another train Y start from Ghaziabad at 4p.m and reaches Meerut at 5.30 p.m . The two train will cross each other at

### Answer : A

### Explanation

Let the distance between meerut and Ghaziabad be x km. Time taken by y to cover x km =3/2 hours. Time taken by X to cover x km = 1 hours Speed of x = xkm/hr speed of y = 2x/3 km/hr Xy+2xy/3 =x ⇒ y (1+2/3) =1 ⇒ y = 3/5 hours = (3/5*60) min. =36 min. Hence, the two train meet at 4.36 p.m
