Watermelon that stood in the sun
Looking at the solid part, 1% of watermelon before sun corresponds to 10 grams. After the sun, this same solid part now corresponds to 2% of watermelon.

That is, its net part weighs 490 grams.
Adding its solid part, 10 grams, the watermelon after dehydration weighs 500 grams.
