RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
12

To determine the minimum number of straight lines in the figure, follow these steps:

  1. Visually inspect the figure and identify all unique straight lines.
  2. Track each line vertically, horizontally, and diagonally to ensure they are not counted more than once.

In the given figure:

  • There are 3 vertical lines.
  • There are 3 horizontal lines.
  • There are 6 diagonal lines forming an 'X' shape across different sections.

Adding these gives a total:

  • \(3 \text{ (vertical lines)} + 3 \text{ (horizontal lines)} + 6 \text{ (diagonal lines)} = 12 \text{ lines}\)

Hence, the minimum number of straight lines in the figure is 12.

The correct answer is 12.
