4 mat-weavers can weave 4 mats in 4 days. At the same rate, how many mats would be woven by 8 mat-weavers in 8 days?	Choose the correct choice from the following choices
A) 16 B) 77 C) 88 D) 26 E) 29
Explanation:   Let the required number of bottles be x.   More weavers, More mats (Direct Proportion)   More days, More mats (Direct Proportion)   {\color{Blue} \left.\begin{matrix} weavers &amp;4:8 \\ days&amp; 4:8 \end{matrix}\right\}::4:x}   {\color{Blue}\therefore }4 x 4 x x = 8 x 8 x 4   {\color{Blue}\Rightarrow x=\frac{8\times 8\times 4}{4\times 4} }   {\color{Blue} \Rightarrow }x = 16.   16nswer: 16) 16
