Time and Work

In this post, we shall discuss about the Time and Work. Lets start with some basic formulas.

Work = Strength X Time
 =>   Strength X Time = Work
=>   (Strength X Time ) / Work = 1   :)

So, For every Case  
(Strenth X Time) / Work = 1      [ No matter the values]

So, (SxT)/W will be same for all the cases.

 I mean   st/w  =  ST/W

Keep this point in your mind. 

Now lets see some more important formulas 

  • If Days are Given :

    • If A can do some work in n days, then he can do 1/n work in One day

  • If Work is Given :

    • If A can do 1/n work in One day, he can finish it in n days 

  • If A is TWICE as good a work man as B, then 

    • The ratio of work done by A and B = 2:1
    • The ratio of time taken by A and B to finish the work = 1:2 (Please Dont be confused)
Now lets do some problems on Time and Work >>

    1. For which exam you are appearing friend?

      see if you are going to write IBPS Clerks then there wont be marketing. If you want to prepare for SBI then there is no Banking Awareness. So please be clear

      If you asked for IBPS Clerks, then our Banking Awareness materials are more than enough ..

      All The Best
