. A and B can finish a work in 16 days while A alone can do the same work in 24 days. In how many days B alone will complete the work?
Answers
Explanation:
Let W be the total work units.
Rates of output are A= u units/day B=v units per day.
W/(u+v)=16
W/u=24
16(u+v)=24u
8u=16v
v=0.5u
No of hours taken byB alone =W/v=2W/u
=2*24=48 hrs.
Answer:
A and B can do a piece of work in 16 days and A alone can do it in 24 days. How long will B alone take to complete the work?
