Detailed Solution
Download Solution PDFGiven:
(Raju + Rajat) together complete the work = 5 days
Raju alone can complete the work = 7 days.
Formula used:
Total work = efficiency × time
Calculation:
Efficiency | Person | Time | Total work |
7 | Raju + Rajat | 5 | 35 |
5 | Raju | 7 |
Now,
Efficiency of Rajat = (7 - 5) = 2 unit/day
Time taken to complete the work by Rajat = 35/2 = 17.5 days
∴ The correct answer is 17.5 days.
