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   =&gt;x∗4∗4=8∗8∗4   =&gt;x=16   Option 16
<result>C</result>
