Question

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?

Answer 1

No, they didn't.

Explanation:

If you consider that the 30% of the ingredients were the 28 kilograms of herbs and spices they added after cooking raw ingredients and before packing the soup in cans, then, the raw ingredients represent 70% of the total weight, so:

30% ---- 28 kg (herbs and spices)

70% ---- x= 70*28/30= 65,33 kg (raw ingredients)

So the total weight of soup produced and sold were: 28 kg + 65,33 kg = 93,33 kg

We can consider that a can of soup is 10 ounces = 0,28 kg Aprox.

If 0,28 kg = 1 can of soup,

then 93,33 kg = 333,32 cans of soup (= 93,33 kg/0,28 kg)

So they didn't sell more than 4800 cans of soup A last year.
