A) 12  B) 14  C) 16  D) 18  E) 20

Rationale: "explanation : please always remember , that what exactly we need to calculate before applying chain formula . as in this question we need to find how many mats , right ! so we will compare everything with ` ` number of mats ' ' as , more men , more number of mats ( direct proportion ) more days , more number of mats ( direct proportion ) so , it can be solved as , [ weavers 4 4 days 8 8 ] : : 4 : x = > x ∗ 4 ∗ 4 = 8 ∗ 8 ∗ 4 = > x = 16 option c"
Answer: C
