Choose the most appropriate option
A) 25 B) 19 C) 39 D) 61 E) 16
Let the required number of bottles be x.   More weavers, More mats (Direct Proportion)   More days, More mats (Direct Proportion)   Wavers	4	:	10 :: 4 : x   Days	4:10   4 * 4 * x = 10 * 10 * 4   x =	(10 * 10 * 4)/(4 x 4)   x = 25.   25nswer is 25.
