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 ?

Solution (By Examveda Team)

$$\eqalign{ & \frac{{{4_{{\text{mat - wevers}}}} \times {4_{{\text{days}}}}}}{{{4_{{\text{mats}}}}}} = \frac{{{8_{{\text{mat - wevers}}}} \times {8_{{\text{days}}}}}}{{{{\text{N}}_{{\text{mats}}}}}} \cr & \Leftrightarrow {\text{N}} = {\text{16 mats}} \cr} $$
