A and B together can do a piece of work in 8 days. B alone can do it in 12 days. B alone works at it for 4 days. In how many more days after that could A alone complete it.
Answers
Answer:
A alone can do
1/8 – 1/12 = 1/24 of the work in 1 day, i.e., A alone can do the same work in 24 days.
B's days' work = 1/12
=> B's 4 days' work
= 4/12 = 1/3
Therefore remaining 2/3 of the work is done by A alone in 2/3 × 2/4 = 16 days.

First of thank you to post this question a awesome one
We can't express what we feel or how much we love our parents through words
It's our deeds or what we can say that we got someone to really care about us is our parents...
Don't know how much in this whole world respect their parents or not but LOVING them giving them everything they had given to us is our work
to make them happy.
Every thing even they sacrificed themselves for us
At last Parents are Life take care of them
