Detailed Solution
Download Solution PDFGiven:
Ravi can do a piece of work = 40 days
Sudha can do the same work = 60 days
Formula used:
Total work = efficiency × time
Calculation:
| Efficiency | Person | Time | Total work |
| 3 | Ravi | 40 | 120 |
| 2 | Sudha | 60 |
According to the question:
⇒ (Sudha + Ravi) = 2 days
⇒ (2 + 3) = 5 units = 2 days
⇒ 5 × 24 = 120 units = 2 × 24 = 48 days.
∴ The correct answer is 48 days.
