1. A can finish a work in 18 days and B can do the same work in half the time taken by A. Then, working together, what part of the same work they can finish in a day ?
- A. 2/5
- B. 2/5
- C. 2/5
- D. 2/5
Answer: Option B
Explanation:
Hints: Given that B alone can complete the same work in day = half the time taken by A = 9 days
A's One day's work = 1/18
B's One days work = 1/9
(A + B)'s one days work = 1/18 + 1/9 = 1/6
