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?
Answer
Explanation
Let the required number of mats be $x$. More weavers, More mats (Direct Proportion) More days, More mats (Direct Proportion) $\left.\begin{array}{ll}\text { Weavers } & 4: 8 \\ \text { Days } & 4: 8\end{array}\right\}:: 4: x$ $$\therefore 4 \times 4 \times x=8 \times 8 \times 4 \Leftrightarrow x=\frac{(8 \times 8 \times 4)}{(4 \times 4)}=16 \text {. }$$
