Download Solution PDFGiven:
30 men can complete a work = 12 days
Formula used:
Total work = efficiency × time
Calculation:
Let, the efficiency of a man = M
According to the question:
⇒ (30 × M × 6) + (54 × M × D) = 30 × M × 12
⇒ (54 × M × D) = 30 × M × 6
⇒ D = (30 × 6)/54 = 10/3
⇒ D = 3
∴ The correct answer is 3
