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 180 units. Receive 50, issue 57, and accept 7 inspected returns into stock. Of the resulting physical stock, 10 units are quarantined; 36 other usable units are reserved. A new order requests 130 units. Reserved and quarantined units cannot fulfil it. No other movements occur. Calculate the units available for the new order. Keep intermediate values unrounded; round the final answer to 4 decimal places if needed.
