Detailed Solution
Download Solution PDFGiven:
10 men can do work = 25 days
Formula used:
Total work = efficiency × time
Calculation:
Let the efficiency of a man = M
According to the question:
⇒ 10 M × 25 = 10 M × 12 + 13 M × D
⇒ 250 M - 120 M = 13 M × D
⇒ 13 M × D = 130 M
⇒ D = 130/13 = 10 days
∴ The correct answer is 10 days.
