Question : 21 [SSC CGL Prelim 2000]
The length of a train and that of a platform are equal. If with a speed of 90 km/hr the train crosses the platform in one minute, then the length of the train (in metres) is :
a) 600
b) 750
c) 900
d) 500
Answer »Answer: (b)
Using Rule 1,If a train crosses an electric pole, a sitting/standing man, km or mile stone etc. then distance = Length of train. Then,Length of train = Speed × TimeAnd Time = $\text"Length of train"/\text"Speed"$ andSpeed = $\text"Length of train"/\text"Time"$
Let the length of train be x metre Speed = 90 km/hr
= ${90 × 5}/18$ metre /sec. = 25 metre/sec.
Distance covered in 60 sec.
= 25 × 60 = 1500 metres
Now, according to question,
2x = 1500 ⇒ x = 750 metre
Question : 22 [SSC CGL Prelim 2005]
A train, 150 m long, takes 30 seconds to cross a bridge 500 m long. How much time will the train take to cross a platform 370 m long ?
a) 30 secs
b) 24 secs
c) 18 secs
d) 36 secs
Answer »Answer: (b)
Using Rule 10,
When a train croses a bridge, distance covered
= length of (bridge + train).
Speed of train = ${150 + 500}/30$
=$650/30 = 65/3$ m/sec.
Time taken to cross the 370m long platform
= ${370 + 150}/{65/3}$
= ${520 × 3}/65$ = 24 seconds
Question : 23 [SSC CPO S.I.2005]
A train takes 18 seconds to pass through a platform 162 m long and 15 seconds to pass through another platform 120 m long. The length of the train (in m) is :
a) 80
b) 90
c) 105
d) 70
Answer »Answer: (b)
Using Rule 10,
Let the length of the train be x metres.
When a train corsses a platform it covers a distance equal to the sum of lengths of train and platform.
Also, the speed of train is same.
${x + 162}/18 = {x + 120}/15$
6x + 720 = 5x + 810
6x - 5x = 810 - 720
x = 90
The length of the train = 90m.
Question : 24 [SSC CGL Tier-I 2016]
The lengths of a train and that of a platform are equal. If with a speed of 90 km/hr the train crosses the platform in one minute, then the length of the train (in metres) is
a) 600
b) 750
c) 900
d) 500
Answer »Answer: (b)
Let, length of train = length of platform = x metre
Speed of train = 90 kmph
= $({90 × 5}/18)$ m/sec.
= 25 m/sec.
Speed of train
= $\text"Length of train and platform"/ \text"Time taken in crossing"$
25 = ${2x}/60$
2x = 25 × 60
$x = {25 × 60}/2$ = 750 metre
Question : 25 [SSC CAPFs SI 2013]
A train 270 metres long is running at a speed of 36 km per hour, then it will cross a bridge of length 180 metres in :
a) 45 sec
b) 50 sec
c) 35 sec
d) 40 sec
Answer »Answer: (a)
Using Rule 10,
36 kmph = $(36 × 5/18)$ m/sec.
= 10 m/sec.
Required time = ${270 + 180}/10$
= 45 seconds
