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)
