Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
30 grams of sugar are 20% of sugar syrup bottle
2. What is the percentage of sugar if we add 10 grams of it?
We can find out the solution, using the Direct Rule of Three this way:
Sugar (grams) Percentage
30 20
40 x
************************************
30x = 40 * 20
30x = 800
x = 800/30
x = 26.67
If you add 10 grams of sugar, you will get 40 grams of 27% sugar syrup (rounding to the next whole).
