Consider a five-digit number PQRST that has distinct digits P, Q, R, S and T, and satisfies the following conditions:
$$ \begin{aligned} & P < Q \\ & S > P > T \\ & R < T \end{aligned} $$
If integers 1 through 5 are used to construct such a number, the value of $P$ is:
A color model is shown in the figure with color codes: Yellow (Y), Magenta (M), Cyan (Cy), Red (R), Blue (BI), Green (G), and Black (K).
Which one of the following options displays the color codes that are consistent with the color model?

An object is said to have an n-fold rotational symmetry if the object, rotated by an angle of $\frac{2 \pi}{n}$, is identical to the original.
Which one of the following objects exhibits 4-fold rotational symmetry about an axis perpendicular to the plane of the screen?
Note: The figures shown are representative.
Five cubes of identical size and another smaller cube are assembled as shown in Figure A. If viewed from direction X, the planar image of the assembly appears as Figure B.

If viewed from direction Y, the planar image of the assembly (Figure A) will appear as
