Parts Inventory: Physical, Usable and Available Stock

Parts Inventory: Physical, Usable and Available Stock

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.

A parts bin opens with 160 units. Receive 45, issue 54, and accept 6 inspected returns into stock. Of the resulting physical stock, 9 units are quarantined; 34 other usable units are reserved. A new order requests 120 units. Reserved and quarantined units cannot fulfil it. No other movements occur. Calculate the units of the new order that can be filled now. Keep intermediate values unrounded; round the final answer to 4 decimal places if needed.
