A and B together can complete a piece of work in 16 days. B alone can complete the same work in 24 days. In how many days can A alone complete the same work
- 34 days
- 50 days
- 48 days
- 42 days
- None of these
- Explanation:
Let A can complete the same work in x days.
∴ A's 1 day's work = 1/x
B'x 1 day's work = 1/24
According to question,
1/x+1/24=1/16
24+x/24x=1/16
16×24+16x=24x
384=24x-16x
x=384/8= 48 days
