I have more then two years of experience in home teaching in mathematics , create visualization in geometry, percentage and time and work, chapter , with different different tricks .
Ex - A can do a piece of work in 8 day , B can do in 6 day and similarly C can do it in 4 day , calculate in how many day A, B ,C together can do a piece of work in how many days ?
solution
Taking L.C.M OF A,B,C (8,6,4) =24
L.C.M = Total work
efficiency of A,B,C are =(3,4,6)
total time taken ?
Total work =(Total time)*(total efficiency)
Total time=(Total work)/(total efficiency)
=(24)/(3+4+6)
Total time= 1.84 day
= 2 days (approx)


Total time taken to complete a piece of work by ( A,B,C) in = 2 day
