Detailed Solution
Download Solution PDFGiven:
Sarthak alone can design the entire room = 12 days
Mohan alone can design the entire room = 15 days
Formula used:
Total work = efficiency × time
Calculation:
| Efficiency | Person | Time | Total work |
| 5 | Sarthak | 12 | 60 |
| 4 | Mohan | 15 |
Now,
Sarthak and Mohan together complete the work = 60/(5 + 4)
⇒ 60/9 = 6.67 days
∴ The correct answer is 6.67 days.
