Chocolate 7121

Setters Janko and Danko argued. She ate twice as much chocolate as I did! Janka shouted at her sister. "So what, yesterday you ate mine and your Horalka!" answered Danka. How many more sweets did Janka eat if the whole chocolate was 600 grams and Horalka 150 grams?

Correct answer:

x =  100 g

Step-by-step explanation:

C=600 g H=150 g D=2/3 C=2/3 600=400 J=2 H+C/3=2 150+600/3=500  x=JD=500400=100 g
