Q:
A) 43/3 days | B) 40/3 days |
C) 50/3 days | D) 41/2 days |
Answer: B) 40/3 days
Explanation:
Explanation:
A takes 24 days to complete a work.
B is 20% more efficient than A,
hence B will take (24*100)/120 = 20 days.
C takes (20+10) = 30 days.
Time taken by A & C in completing the work = (24*30)/(24+30) = (24*30)/54 = 40/3 days.
