A can do a piece of work in 20 days and B in 30 days. A starts the work and worked for 6 days. Then B completed the remaining part of the work. In how many days was the work completed?
Read Solution (Total 2)
-
- A one day work = 1/20
B one day work = 1/30
A 6 day work = 6/20
Let B works for x days
B x day work = x/30
Now since A and B complete the work
6/20+x/30=1
Which gives x as 21
Now total no. of days=21+6=27days - 12 years agoHelpfull: Yes(5) No(0)
- 6 days A worked=6/20
work remaining=14/20
B done remaining work in=14/20*30=21 days - 13 years agoHelpfull: Yes(0) No(4)
