Parts Orders: Allocating a Limited Receipt in FIFO Order

Parts Orders: Allocating a Limited Receipt in FIFO Order

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.

Three backorders must be served in order A, then B, then C. Their quantities are A=40, B=49, C=72 units. A receipt supplies 101 usable units. There is no other stock. Partially filling an order is allowed. A later second receipt contains 18 units and continues the same queue. Calculate the units allocated to C from the first receipt. Keep intermediate values unrounded; round the final answer to 4 decimal places if needed.
