Question : 1 [SSC CPO S.I.2003]
A moving train passes a platform 50 metres long in 14 seconds and a lamp-post in 10 seconds. The speed of the train is
a) 36 km/hr.
b) 40 km/hr.
c) 45 km/hr.
d) 24 km/hr.
Answer »Answer: (c)
Rule 10 and Rule 1,
Suppose length of train be x
According to question
${x + 50}/14 = x/10$
14x = 10x + 500
4x = 500
$x = 500/4 = 125 m$
Therefore, speed
=$125/10 × 18/5 = 45$ kmph
Question : 2 [SSC MTS 2013]
Two trains 100 metres and 95 metres long respectively pass each other in 27 seconds when they run in the same direction and in 9 seconds when they run in opposite directions. Speed of the two trains are
a) 52 km/hr, 26 km/hr
b) 36 km/hr. 18 km/hr
c) 40 km/hr, 20 km/hr
d) 44 km/hr, 22 km/hr
Answer »Answer: (a)
Let the speed of trains be x
and y metre/sec respectively,
${100 + 95}/{x - y} = 27$
$x - y = 195/27 = 65/9$ ...(i)
Again,
$195/{x + y} = 9$
$x + y = 195/9$ ...(ii)
By equation (i) + (ii)
$2x = 65/9 + 195/9 = 260/9$
$x = 260/{2 × 9} = 130/9$ m/sec.
= $(130/9 × 18/5)$ kmph = 52 kmph
From equation (ii),
$y = 195/9 - 130/9 = 65/9$ m/sec.
= $65/9 × 18/5$ = 26 kmph
Question : 3 [SSC CPO S.I.2008]
A train passes a platform 110 m long in 40 seconds and a boy standing on the platform in 30 seconds . The length of the train is
a) 110 m
b) 220 m
c) 330 m
d) 100 m
Answer »Answer: (c)
Rule 10 and Rule 1,
Let the length of the train be x metres.
Speed of train in crossing boy = $x/30$
Speed of train in crossing platform = ${x +110}/40$
According to the question,
${x +110}/40 =x/30$
${x +110}/4 = x/3$
4x = 3x + 330
x = 330 metres
Question : 4 [SSC CGL Prelim 2005]
A train passes a man standing on a platform in 8 seconds and also crosses the platform which is 264 metres long in 20 seconds. The length of the train (in metres) is :
a) 176
b) 175
c) 96
d) 188
Answer »Answer: (a)
Rule 10 and Rule 1,
Let length of train be x m
Speed of train = ${x + 264}/20$
Also, speed of train = $x/8$
Obviously, $x/8 = {x + 264}/20$
$x/2 = {x + 264}/5$
5x = 2x + 528
5x - 2x = 528
x = 528 ÷ 3 = 176 m
Question : 5 [SSC CGL Tier-I 2016]
The time for a train of length 110 metre running at the speed of 72 km/hr to cross a bridge of length 132 metre is
a) 12.1 seconds
b) 12.42 seconds
c) 14.3 seconds
d) 9.8 seconds
Answer »Answer: (a)
Speed of train = 72 kmph.
= $({72 × 5}/18)$ m./sec. = 20 m./sec.
Required time
= $\text"Length of train and bridge"/ \text"Speed of train"$
= $({110 +132}/20)$ seconds
= $(242/20)$ seconds = 12.1 seconds
