typo (Question: 108565.0 )

conecutively ki jagah together vapro na

Question:
 A’s efficiency is half of B, and C does half of the work done by A and B consequently. If C alone does the work in 20 days, then in how many days A, B and C together can do that piece of work?
Options:
A) \(5\cfrac{2}{3}\) days
B) \(6\cfrac{2}{3}\) days
C) 6 days
D) 7 days
Solution:
Ans: (b)

C alone can do the work in 20 days

\(\therefore\) Total time taken by (A+B) to complete the work = \(\cfrac{20}{2}\) = 10 days

Hence, total time taken by (A+B+C) to complete the work
