Q 1 - A train 210 m long is travelling with a speed of 63 kmph. How long will it take to pass a signal post?
Answer : A
Explanation
speed =(63*5/18)m/sec =35/2 m/sec Required time =(210*2/35) sec. =12 sec.
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 270 m long is moving at a speed of 25 kmph. It will cross a man coming from the opposite direction at a speed of 2kmph in
Answer : A
Explanation
Their relative speed =(25+2)kmph =27kmph = (27*5/18) m/sec. =15/2 m/sec. Required time = 270/ (15/2) sec. = (270*2)/15 sec.= 36 sec.
Q 4 - A train overtakes two persons two persons walking in the same direction in which the train is going. These persons are walking at the rate of 2km/hr and 4km/hr and the train passes them completely in 9 sec. and 10 sec. respectively. The length of the train is
Answer : C
Explanation
let the length of the train be X km and its speed be y km/hr. Speed of the train relative to first man = (y-2) km/hr Speed of the train relative to second man =(y-4)km/hr ∴ x/(y-2) = 9/(60*60) and x/(y-4) =10/(60*60) ⇒ y-2 =400x and y-4 =360x ⇒ 400x+2=360x+4 ⇒40x=2 ⇒x=1/20km =(1/20*1000)m= 50m ∴ length of the train =50m
Q 5 - Two trains A and B start running together from the same point in the same direction at 60 kmph and 72 kmph. If the length of each train is 240 m, how long will it take for the train B to cross train A ?
Answer : D
Explanation
Relative speed =(72-60)kmph =12kmph =(12*5/18)m/sec = 10/3m/sec. Total distance covered= (240+240)m= 480m Required time =(480*3/10)sec. =144 sec.= 2 min.24 sec.
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 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
