Answer & Solution
Answer: Option D
Solution:
Let the required number of bottles be x.
More weavers, More mats (Direct Proportion)
More days, More mats (Direct Proportion)
\[\left. \begin{gathered}
{\text{Wavers}}\,\,\,\,4:8 \hfill \\
\,\,\,\,\,\,{\text{Days}}\,\,\,\,4:8 \hfill \\
\end{gathered} \right\}::4:x\]
$$\eqalign{
& \therefore 4 \times 4 \times x = 8 \times 8 \times 4 \cr
& \Rightarrow x = \frac{{ {8 \times 8 \times 4} }}{{4 \times 4}} \cr
& \Rightarrow x = 16 \cr} $$
