Match the following. 
Step 1: Understanding the Concept:
This question requires knowledge of fundamental concepts in color theory to match the visual examples with the correct terms.
Step 2: Defining the Terms:
P. Complementary: Colors that are opposite each other on the color wheel (e.g., red and green). They create high contrast.
Q. Spectrum: A continuous band of colors, like a rainbow, showing the full range of visible light.
R. Cool: Colors associated with coolness, like blues, greens, and violets.
S. Harmony: The pleasing arrangement of colors in a design, based on established color schemes (e.g., analogous, triadic).
Step 3: Analyzing and Matching the Images:
Image 1: Shows a continuous gradient of all colors, transitioning smoothly from one to the next. This is a visual representation of the color Spectrum (Q).
Image 2: Displays several palettes composed exclusively of blues, greens, and purples. These are classic Cool (R) colors.
Image 3: Shows different sets of colors that are aesthetically pleasing and work well together. This illustrates the concept of color Harmony (S).
Image 4: Shows pairs of colors that are opposites, creating strong contrast (e.g., yellow and purple, red and cyan, blue and orange). These are Complementary (P) colors.
Step 4: Final Answer:
Based on the analysis, the correct matching is:
1 $\rightarrow$ Q
2 $\rightarrow$ R
3 $\rightarrow$ S
4 $\rightarrow$ P
This corresponds to the sequence 1Q, 2R, 3S, 4P, which is option (B).
The words given below are written using a particular font. Identify the digit that does not belong to the same font.
Shown below is a cross-section which is revolved 270 degrees around the P-Q axis to create a solid. How many surfaces will the resultant solid have?
Shown below is a strip of paper which is folded multiple times. How many red pawns are placed on the same side of the paper as the blue pawn? 
Shown below is an image of multiple footwear items. How many complete pairs are there? 
Shown below is a configuration of an isosceles triangle sliced into eight parts, each of the same height. While the first and last parts of the triangle remain fixed, the remaining parts have been displaced horizontally, by multiples of 0.5 cm. What is the area of the grey portion?
