If 6 men can make 10 sofas in 2 days, then 8 men can make 8 sofas in ______?
- 1.8 days
- 1.5 days
- 1.2 days
- None of these
Explanation
Given:
- 6 men make 10 sofas in 2 days.
First, find the total man-days needed for 10 sofas:
6 men × 2 days = 12 man-days for 10 sofas.
So, man-days per sofa = 12 ÷ 10 = 1.2 man-days per sofa.
Now, for 8 sofas:
Total man-days needed = 8 sofas × 1.2 = 9.6 man-days.
If 8 men are working, number of days needed = 9.6 ÷ 8 = 1.2 days
