Best answer

Correct option (b) 6 days

Explanation: 

 16 women × 12 = 12 men × 8 

 2 women = 1 man 

Total work = 12 men × 8 days = 96 units 

16 men do work in 3 days= 16×3 = 48 units 

Work left 96-48 = 48 units 

16 men – 10 men left = 6 men + 4 women join 6 men + 2 men = 8 men

8 men will do 48 units in 48/8 = 6 days
