Cabinet Panels: Datum Coordinates and Mirrored Hole Patterns

Cabinet Panels: Datum Coordinates and Mirrored Hole Patterns

Original quantitative learning practice in English. All 24 questions are included. Four supplied cases exercise six related calculation targets; they form one topic, not four separate tests. Every question includes the complete initial data. Use the stated model and retain intermediate precision. Choose one answer. Learning target: 20/24, not an official pass mark. This bank covers the calculation topic in its title; it is not a complete professional examination, design approval or operating instruction.

A rectangular panel is 560 mm wide and 800 mm high. Coordinates start at its lower-left corner. The first hole is at (41, 110) mm; a second is 360 mm directly above it. A mirrored panel reflects both holes across the vertical centreline. Hole centres, not hole edges, define every distance. Calculate the mirrored first-hole x coordinate in mm. Keep intermediate values unrounded; round the final result to four decimal places if necessary.
