Solution:

(1) 4 × 8 men + 6 × 8 women = 3 × 10 men + 7 × 10 women
32 men – 30 men = 70 women – 48 women
2 men = 22 women
1 men = 11 women
According to the question, 44 women (4 men) + 6 women = 50 women can complete the work in 8 days.
Therefore, 10 women will complete the work in

{50 ×8}/10

= 40 days
