Solution of Day 13 CSAT PYQ

​Table dimensions: 6' x 10'
​Blue rectangle dimensions: 2.5' x 8' (Quantity: 2)

​Step 1:
Placement Constraint
The problem states each blue portion has "exactly two sides common with two edges of the table top."

This geometrically requires each blue rectangle to be placed exactly into one of the 4 corners of the table.

​Step 2:
Orientation Constraint
Since the table's width is 6' and the blue rectangle's length is 8', the 8' side of the blue rectangle cannot be placed along the 6' edge.

It must be aligned along the 10' edge.

Therefore, the orientation of the blue rectangles within any chosen corner is strictly fixed.

​Step 3:
Calculating Patterns
Because the table is fixed to the ground, we cannot rotate it to make patterns look identical. Every unique selection of corners creates a distinct visual pattern from above.

​To find the total patterns, calculate the number of ways to choose 2 corners out of the 4 available corners:

​4C2 = (4 × 3) / (2 × 1) = 6

​There are 6 possible patterns.

​Correct Answer:

(c) 6
