This blog is about Indian Railways.History of Indian Railways.Indain railways is the larget rail network in whole Asia,and world's second largest rail network .Country's first train ran between Bombay and Thane in 16 April 1853.Our railway system is serving millions of tourists and local passangers everyday.
The New Delhi railway station has secured place in gunniess book of record,for having worlds's largest root interlocking system.

In our previous blog we discussed some important questions of TIME AND WORK .I saw some peoples are facing problem in Que 3.
So today i am here to tell you how to solve the questions in which WORK is divided into parts or fractions.This is another high level type of question asked in RRB (CBT2)and other competitive examinations.
Time and work Trick
This is most important question from the railway point of view .Frankly telling friends when i started reading TIME AND WORK from book ,i failed to solve such type of questions.But we are going to solve this question from the same Trick i discussed in my previous post.Just use one trick and solve all types of questions based on time and work.
WORK=Efficiency*Time
This is the formulae we discussed earlier.Friends you can also find
EFFICIENCY=Work/Time and similarly,
TIME = Work/Efficiency
In question above first break the fraction into days
SoA do 2/5 part of work in=10*5/2 =25 days
andB do 1/2 part of same work in =10*2 =20 days
Now solve this by normal method discussed earlier
EfficiencyTime Total work
4 A 25
100
5 B 20
NOTE: Effieiency =Work/Time
Total Work = Efficiency*Time also( LCM of 25&20)
A and B working together for 5 days=(5+4) i.e Effi. of A+Effi. of B*5
=(5+4)*5=45 work the do together.
Total work is 100 and 45 Work is done by A+B,so Total work left is (100-45)=55
Now see que. In how many days will B finish the remaining work.
i.e Total work left/Efficiency of B=55/5=11 days
So,B alone finished the remaining work in 11 days.ANS

See the images above question no1-6.These are the questions made on TIME AND WORK.
HOW TO USE THIS TRICK?
Important thing you need to remember is .
WORK=TIME*EFFICIENCY
Always take the LCM of days i.e
Q If A is doing a work in 12days and B in 24 days ,how much time they take to finish the work together .
An. Now take LCM of 12 and 24 which is 24,
now take 24 as a total work.
Efficiency =Work/time.
so efficiency of A is 2 and B is 1.
so they both take=2+1=3 efficiency.
Now divide 3 by 24(Total Work)
now ans is 24/3=8days
See the questions in images to get better idea.
Always remember the formulae given above.This trick may solve question in just 20-25 seconds, There is no trick better than this trick.Once you start using this trick you may see your speed is increasing.This is benificical in all Competitive Examinations.RRB GROUP D ,RRB ALP ,RRB JE,RRB NTPC,RPF.Practice these questions ,trick is also helpful in PIPE AND CISTERN
