Q1: 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?

ANS:D - 16

Let the required number of bottles be x. More weavers, More mats (Direct Proportion) More days, More mats (Direct Proportion)

Wavers	4	:	8		:: 4 : x
Days	4	:	8

 4 x 4 x x = 8 x 8 x 4

x =	(8 x 8 x 4)
	(4 x 4)

 x = 16.
