Answer: <em>230 - the total amount of sweets.</em>
Step-by-step explanation:
<em>Adrian received 8 pieces of sweets;</em>
<em>Ben got 5 pieces of sweets;</em>
<em>Charlie received 10 pieces of sweets.</em>
<em>The sum of all parts:</em>
8 + 5 + 10 = 23
<em>Let's calculate how many parts Charlie got more than Adrian:</em>
10 - 8 = 2
<em>It is also known that Charlie received 20 more sweets than Adrian. This means that you can calculate how many sweets are in one part.</em>
<em>20 : 2 = 10</em>
<em>Now we can calculate the total amount of sweets:</em>
<em>10 × 23 = 230</em>
