Maximum allowance available when the hole size is and shaft size is .

Correct option is D

· Hole size:
· Minimum hole size = 55 + 0.010 = 55.010 mm
· Maximum hole size = 55 + 0.050 = 55.050 mm
· Shaft size:
· Minimum shaft size = 55 - 0.30 = 54.70 mm
· Maximum shaft size = 55 - 0.15 = 54.85 mm
Formula for Maximum Allowance:
Maximum Allowance = Maximum Hole Size − Minimum Shaft Size
Calculation:
Maximum Allowance = 55.050 − 54.700 = 0.160 mm
