A soup for 4 servings uses 240 grams of carrots and 800 millilitres of stock. Which proposed batches keep those two ingredients in the same recipe proportions? Select all that apply.

Explanation

The recipe has 60 grams of carrots and 200 millilitres of stock per serving, so the six-serving and eight-serving batches scale both ingredients consistently. The five-serving proposal has the right 300 grams of carrots but should use 1,000 millilitres of stock, making its 900-millilitre figure the closest mixed-scaling error.
