#9 Problems on Trains

Two stations P and Q are 110 km apart on a straight track. One train starts from P at 7 a.m. and travels towards Q at 20 kmph. Another train starts from Q at 8 a.m. and travels towards P at a speed of 25 kmph. At what time will they meet?

A) 10.30B) 10C) 8.45D) 9.30

Answer: B) 10 

Explanation:

Assume both trains meet after x hours after 7 am

Distance covered by train starting from P in x hours = 20x km

Distance covered by train starting from Q in (x-1) hours = 25(x-1)

Total distance = 110

=> 20x + 25(x-1) = 110

=> 45x = 135

=> x= 3

Means, they meet after 3 hours after 7 am, ie, they meet at 10 am

#7 Problems on Trains

Two trains having equal lengths, take 10 seconds and 15 seconds respectively to cross a post. If the length of each train is 120 meters, in what time (in seconds) will they cross each other when traveling in opposite direction?

A) 10 B) 25 C) 12 D) 20

Answer: C) 12 

Explanation:

Speed of train 1 =  = 12 m/sec

Speed of train 2 =  = 8 m/sec

if they travel in opposite direction, relative speed = 12 + 8 = 20 m/sec

distance covered = 120 + 120 = 240 m

time = distance/speed = 240/20 = 12 sec

#6 Problems on Trains

Two trains 140 m and 160 m long run at the speed of 60 km/hr and 40 km/hr respectively in opposite directions on parallel tracks. The time (in seconds) which they take to cross each other, is:

A) 9 B) 9.6 C) 10 D) 10.8

Answer: D) 10.8 

Explanation:

Relative speed
= (60 + 40) km/hr =[ 100 x ( 5 / 18 ) ]m/sec = ( 250 /9 ) m/sec.
Distance covered in crossing each other
= (140 + 160) m = 300 m.
Required time = [ 300 x ( 9/250 ) ] sec = ( 54/ 5 )sec = 10.8 sec.

A) 69.5 km/hr B) 70 km/hr C) 79 km/hr D) 79.2 km/hr

Answer: D) 79.2 km/hr 

Explanation:

Let the length of the train be x metres and its speed by y m/sec.
Then,
Now,  
8y + 264 = 20y
y = 22.
Speed = 22 m/sec =km/hr = 79.2 km/hr.

#2 Problems on Trains

A man sitting in a train which is traveling at 50 kmph observes that a goods train, traveling in opposite direction, takes 9 seconds to pass him. If the goods train is 280 m long, find its speed.?

A) 60 B) 62 C) 64 D) 65

Answer: B) 62 

Explanation:

Relative speed =  m / sec =  kmph = 112 kmph.

Speed of goods train = (112 - 50) kmph = 62 kmph.

#1 Problems on Trains

A jogger is running at 9 kmph alongside a railway track is 240 meters ahead of the engine of a 120 meters long train running at 45 kmph in the same direction. In how much time will the train  pass the jogger ?

Answer: B) 36 sec 

Explanation:

Speed of the train relative to jogger = (45-9) km/hr = 36 km/hr

= = 10 m/sec

Distance to be covered =(240 + 120)m = 360 m

 Time taken =  sec = 36 sec

#3 Problems on Trains

A) 230 mB) 240 mC) 260 mD) 320 m

Answer: A) 230 m 

Explanation:

Relative speed = (120 + 80) km/hr
==

Let the length of the other train be x metres.

Then, 

 x + 270 = 500

 x = 230.

#5 Question Analytical Reasoning


#5 What is the number of straight lines and the number of triangles in the given figure.
A) 10 straight lines and 34 trianglesB) 9 straight lines and 34 triangles
C) 9 straight lines and 36 trianglesD) 10 straight lines and 36 triangles
 Answer & ExplanationAnswer: C) 9 straight lines and 36 triangles

Explanation:
http://www.sawaal.com/qaimg/an-reasoning2a.png
The Horizontal lines are DF and BC i.e. 2 in number.
The Vertical lines are DG, AH and FI i.e. 3 in number.
The Slanting lines are AB, AC, BF and DC i.e. 4 in number.
Thus, there are 2 + 3 + 4 = 9 straight lines in the figure.
Now, we shall count the number of triangles in the figure.
The simplest triangles are ADE, AEF, DEK, EFK, DJK, FLK, DJB, FLC, BJG and LIC i.e. 10 in number.
The triangles composed of two components each are ADF, AFK, DFK, ADK, DKB, FCK, BKH, KHC, DGB and FIC i.e. 10 in number.
The triangles composed of three components each are DFJ and DFL i.e. 2 in number.
The triangles composed of four components each are ABK, ACK, BFI, CDG, DFB, DFC and BKC i.e. 7 in number.
The triangles composed of six components each are ABH, ACH, ABF, ACD, BFC and CDB i.e. 6 in number.
There is only one triangle i.e. ABC composed of twelve components.
There are 10 + 10 + 2 + 7 + 6+ 1 = 36 triangles in the figure.

#4 Question Analytical Reasoning

#4 Find the minimum number of straight lines required to make the given figure.
A) 9B) 11
C) 15D) 16
 Answer & ExplanationAnswer: B) 11

Explanation:
  
The horizontal lines are DE, FH, IL and BC i.e. 4 in number.
The slanting lines are AC, DO, FN, IM, AB, EM and HN i.e. 7 in number.
Thus, there are 4 + 7 = 11 straight lines in the figure.
