Which tolerance is defined as 2 mm or 1% on a side?

• A. 2 mm or 1% on a side
• B. 1 mm or 1% on a side
• C. 1 mm
• D. 2 mm

Answer: (A)

This tests your ability to read a mixed absolute/relative tolerance that is applied per side. When a spec says “2 mm or 1% on a side,” the deviation allowed for each side of the dimension is governed by both criteria: a fixed amount (2 mm) and a percentage of the nominal size (1%). The per-side wording means you consider the allowance on the positive and negative directions from the nominal separately, not as a single total tolerance. This exact phrasing is the best match because it communicates both the fixed and the relative control and that it applies per side. Other options that give only a single value or omit the “on a side” detail don’t capture the same mixed, per-side tolerance.
