To calculate how many grams of sugar are in a 200 ml glass of apple juice, given that 250 ml contains 25.5 g of sugar, you can use a simple proportion:

$\text{sugar in 250 ml} = 25.5 \, \text{g}$

We want to find the sugar content in 200 ml:

$\frac{\text{sugar in 200 ml}}{200 \, \text{ml}} = \frac{25.5 \, \text{g}}{250 \, \text{ml}}$

Now solve for the sugar content in 200 ml:

$\text{sugar in 200 ml} = \frac{200 \times 25.5}{250}$

Let me calculate this for you.The amount of sugar in a 200 ml glass of apple juice is 20.4 grams.
