MATH TRICKS , TIME AND WORK /PIPE AND CISTERN

TIME AND WORK TRICKS NOTES

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

Efficiency                       Time            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
