Correct Answer - Option 1 : 9 days
Given:
Man completes the task in 6 hour
A man works for 36 days
Concept used:
1 day = 24 hours
Calculation:
In 1-day man works for 6 hours
In days man works for 6 × 36 = 216 hours
Now, 24 hours = 1 day
1 hour = 1/24 days
216 hour = (1/24) × 216 = 9 days
∴ Time taken by man is 9 days
