**Question:**

A man can do the work in 16 days. But a woman can do that work in 24 days. 1) a woman can start the work continues and man can joined the work at the end of 4days how many days to complete that work? 2)a woman can start that work after 4 days man can joined in how many days to complete that total work?

18&12

1. 18

2. 12

16 days is the perfect ans see my explanation __frdz__

Both of them can complete the work in:-

1/16+1/24=5/48

=48/5 days

We can se that total work to be done is 48.

Daily work done by both of them is 5.

Daily work done by man is 3.

Daily work done by women is 2.

woman starts and man joins 4 day after woman.

So work done by woman in 4 days is 8 units.

Left work:- 40 units

Together they do 5 units per day.

So they complete the remaining work in:-

=40/5= 8 more days

Total time to complete total work is 12 days.

16

24*16/40=48/5

Man n woman together can complete 48/5 days.

In 4 days the work completed (5/48)*4=5/12

So 5/12 part is completed in 4 days and remaining part was completed by only woman. So (1-(5/12))=7/12 so the remaking part completed in( 7/12)*24=14 days

Therefore 14+4= 16 days

16 days is the and for two questions.

Woman and man can complete a work in 48/5=9.6days

Now in 4days woman completes 4/24 work and is left with 20/24work

Now, (20/24)*(48/5) = __8days__

plz explain in brief ?? i cudn't understand it

8more days

Total 8+4=__12days__

8 more __days__
