Given,

'A' can cultivated a field in 10 days.

Therefore,'A' can finish work in 1 day is = 1/10th part.

'B' can cultivated a field in 12 days.

Therefore,'B' can finish work in 1 day is = 1/12th part

'C' can cultivated a field in 15 days.

Therefore,'C' can finish work in 1 day is = 1/15th part

To Find,

How many days needed to do work when they whole work together.

Solution,

Therefore,

                ==> 1/10 + 1/12 + 1/15

                ==>  6 + 5 + 4/60

                ==>  15/60

                ==> 1/4

                ==> 4 days

  • NOW WE WANT TO FIND THAT WHAT  THE FRACTION OF THE WORK  WILL EACH OF THEM DONE:

Therefore,                                    

                  ==> 'A' = 4 * 1/10                  

                  ==> 'A' = 2 * 1/5

                  ==> 'A' = 2/5 DAYS

Therefore,

                  ==> 'B' = 4 * 1/12

                  ==>' B' = 1 * 1/3

                  ==> ' B' = 1/3 DAYS

Therefore,

                  ==> 'C' = 4 * 1/15

                  ==> 'C' = 4/15 DAYS

THAT I HOPE IT WILL HELP YOU!!!!!!
