Tolerance on the dimension $$'x'$$ in the two component assembly shown below is (all dimensions are in $$mm$$)

A keyway of $$5$$ $$mm$$ depth is to be milled in a shaft of diameter $$60 \pm 0.1\,\,$$ by positioning the shaft in a $$V$$-block of angle $$120deg$$ and setting the tool with reference to the intersection of the face of the $$V$$-block. The error due to shaft tolerance which would be transferred on to the component is

The surface finish of the component produced by a grinding process was measured. Based on roughness parameters obtained, which one of the following is true

A cylindrical pin of diameter $${1.996^{\matrix{ { + 0.0015} \cr { - 0.0015} \cr } }}\,\,mm$$ is assembled into a hole of diameter $${2.000^{\matrix{ { + 0.0015} \cr { - 0.0015} \cr } }}\,\,mm.$$ The allowance (in $$mm$$) provided for this assembly is
