The width of a screw is to be 20.5 mm, with a tolerance of 0.01 mm. What is the greatest possible width that is acceptable?

f20.5 mm
B.
f20.49 mm
C.

Step 1: The tolerance limit can be expressed as an absolute value inequality | n - 20.5 | ≤ 0.01
Step 2: n - 20.5 ≤ 0.01 or n - 20.5 ≥ - 0.01
Step 3: n ≤ 20.51 or n ≥ 20.49
Step 4: So, the greatest possible width acceptable is 20.51 mm.
