TYPES OF QUESTIONS ON TIME AND WORK

 

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
