Last year, a certain company began producing soup A and sold all of the soup A that it produced. To make all of the soup A produced last year, raw ingredients were cooked until their weight was 30% less than their original weight, then a total of 28 kilograms of herbs and spices were added just before soup A was packaged in cans. Did the company sell more than 4,800 cans of soup A last year?
(1) Each can of soup A sold last year contained 0.45 kilograms.
(2) Last year, the total weight of the raw ingredients for soup A, before cooking and excluding the herbs and spices added after cooking, was greater than 3,000 kilograms.
What we need to answer here is whether company sold >4800 cans of Soup A..
Stmn1 :
each soup A can contained 0.45 kgs : the given info is insufficient as we dont know what was the % of the added herbs and spices in each can , missing info of weight of soup alone is also not there.. 28kgs is the total weight of herbs & spices before its packed.. not sufficient
Stmn 2: total weight of raw ingredients for Soup A before cooking >3000 kgs so after 30% left : 3100*0.7: 2170 kgs after which 28kgs of herbs and spices are being added ..
not sufficient to determine whether >4800 cans are sold as weight per can info is missing..
From 1 & 2 .
if we consider that weight of can 0.45 kgs and total weight of soup +herbs as found from stmn 2 : 2170+28= 2198 ; total cans 2198/.45 = 4884 which is sufficient
in contrast if total weight is 3001kgs , 3001*07; 2100.7+28; 2128.7 ~ 2129 total cans 2129/.45 = ~ 4731 cans ; insufficient
IMO E is correct.
