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.

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
