To measure the effective diameter of an external metric thread (included angle is $$60$$ degrees) of $$3.5$$ $$mm$$ pitch, a cylindrical standard of $$30.5$$ $$mm$$ diameter and two wires of $$2$$ $$mm$$ diameter each are used. The micrometer reading over the standard and over the wires are $$16.532$$ $$mm$$ and $$15.398$$ $$mm$$ respectively. The effective diameter (in $$mm$$) of the thread is
A
$$33.366$$
B
$$30.397$$
C
$$29.366$$
D
$$26.397$$

A small bore is designated as $$25H7.$$ The lower (minimum) and upper (maximum) limits of the bore are $$25.000mm$$ and $$25.021$$ respectively. When the bore is designated as $$25H8,$$ then the upper limit is $$25.033mm.$$ When the bore is designated as $$25H6,$$ then the upper limit of the bore in $$mm$$ is
A
$$25.001$$
B
$$25.005$$
C
$$25.009$$
D
$$25.013$$
