4 mat-weavers can weave 4 mats in 4 days. At the same rate, how many mats would be woven by 16 mat-weavers in 16 days? Choose the correct option:
A) 25	B) 19	C) 39	D) 61	E) 64
Let the required number of bottles be x.   More weavers, More mats (Direct Proportion)   More days, More mats (Direct Proportion)   Wavers	4	:	16 :: 4 : x   Days	4:16   4 * 4 * x = 16 * 16 * 4   x =	(16 * 16 * 4)/(4 x 4)   x = 64.   Answer is 64.
