Baker should use 18-kilogram pack so that no salt is left in the end.
Step-by-step explanation:
In order to find which bag should he buy, we have to check for which bag the 30 grams salt can be taken out completely i.e. which quantity is divided by 30 grams completely.
If a quantity is not divided by 30 completely that means that there will be salt left.
so,
For 800-grams pack:
Salt for one batch of bread = 30-grams
Batches from 800-grams of salt:
<u>For 18-kg pack:</u>
First of all we have to convert the kilograms into grams
As there are 1000 grams in one kilogram,
18 kg = 18*1000 grams = 180000 grams
Batches of bread from 18 kg salt:
As the 18-kilograms is completely divided by 30, so after 600 batches no salt will be left but in 800 gram pack after 26 batches salt will be left.
So,
Baker should use 18-kilogram pack so that no salt is left in the end.
