Aruna can complete a piece of work in 5 days. A takes double the time ...
Given Information:
- Aruna can complete the work in 5 days
- A takes double the time of Aruna (10 days)
- B takes double the time of A (20 days)
- C takes double the time of B (40 days)
Pairing Information:
- Let the first pair be Aruna and B, and the second pair be A and C
- Aruna and B take (5 + 20) = 25 days to complete the work
- A and C take (10 + 40) = 50 days to complete the work
- It is given that the first pair takes two-thirds the time needed by the second pair
Calculations:
- Two-thirds of 50 days is (2/3) * 50 = 33.33 days
- As Aruna and B take 25 days, which is less than 33.33 days, they are the first pair
Therefore, the first pair is (a) Aruna and B as they take less time to complete the work compared to A and C.
