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?

A) 4

B)  8      

C)  12

D)  16

Correct Answer: D

Solution :

\[\therefore \]10 women will finish the work in 40 days. \[\left. \begin{align}   & 4:8 \\  & 4:8 \\ \end{align} \right\}::4:x\] \[\Rightarrow \]   \[4\times 4\times x=8\times 8\times 8\times 4\] \[\therefore \]      \[x=\frac{8\times 8\times 4}{4\times 4}=16\]
