TIME AND WORK
Time and Work Aptitude trick 1
as we all know that If a person has an ability to do the work in 10 days(for example), then the person's one day's work is 1/10.... that means he can do a work 10 times that in day.
TIP NUMBER 1: EFFICIENCY
If a person is more efficient than the other, it may be Twice or Thrice or...etc..
then information given should be taken in the form of RATIO.
Eg: A is twice as good work man as B and together they finish a piece of work in 14 days .
The number of days taken by A alone to finish the the work is??
A B
2 : 1
A+B ==>2+1 => 3-----------X----------- 14
(DIRECTLY PROPORTIONAL)
A==========> 2-----------X-----------x
3 X 14=2x
x=21.
