Bakery Maths: Portion Yield and Sequential Process Losses

Original quantitative topic practice in English. All 24 questions are included in a shuffled order. Each question supplies its own data and model assumptions; use only those assumptions. Choose one answer. Practice target: 20/24, not an official examination pass mark. Keep full intermediate precision. These exercises cover the calculation scope in the title; they do not constitute a full Red Seal examination, trade qualification, site design or operating specification.

Start with 27000 g mixed dough. Handling loses 5% of that mass. Divide all usable dough into pieces of 480 g, leaving any incomplete piece as remainder. Baking loses 12% of each piece's mass. Sell products in packs of 4 pieces. These loss percentages are assumptions for this exercise, not production recommendations. Calculate the complete pieces before baking. Keep intermediate values unrounded; round the final answer to 4 decimal places if needed.
