A solution weighing 500 g contains 40 g of salt. How many grams of salt are in 200 g of the same solution?

The solution of the problem:

500 gr. (Solution) – 40 gr. (Salt)
200 gr. (Solution) – X gr. (Salt)

X gr. (Salt) = (200 gr. (Solution) × 40 gr. (Salt)) / (500 gr. (Solution)) = 16 gr. (Salt)

Otherwise: X = (200 × 40) / 500 = 16 gr. (Salt)

Correct answer: 200 grams of solution contains 16 grams of salt.
