If it took him 2 days to jar 10 liters, then it would take him 3 days to jar 15 liters. First, you need to figure out how many liters he jarred in one day by dividing 10 by 2. Doing this, you will find out that he can jar 5 liters per day. Now you divide 15 by 5 which gives you 3.
If he jars 10 every two days, that means he jars five in one day.

So 10 +5=16

So, he spent three days making jam to get 15 liters.

Hope this helps and please mark brainiest.
