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 - 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:
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
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 - 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
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 - 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 train travel in opposite direction at 36 kmph and 45kmph. A man sitting in a slower train passes the faster train in 8 sec. The length of the faster train is
Answer : D
Explanation
Relative speed =(36+45)km/hr =(81*5/18)m/sec. =45/2m/sec. Length of the train = distance covered in 8 sec. at 45/2m sec. = (45/2*8)= 180 m
Q 7 - A train X speeding with 120kmph cross another train Y, running in the same direction, in 2 min. If the length of the trains X and Y be 100 m and 200m respectively, What is the speed of train Y
Answer : A
Explanation
let the speed of train y be x km/hr. Speed of x relative to y =(120-x) km/hr =[ (120-x)*5/18]m/sec. = (600-5x)/18 m/sec. 300/ (600-5x)/18 =120 ⇒120 (600-5x) =5400 ⇒ 600-5x =45 ⇒ 5x =555 ⇒ x =111 Speed of train y = 111km/hr
