Question

Identify the option that will replace the question mark. 

 

• A. A
• B. B
• C. C
• D. D

Hint:

Even if you don't know Braille, you can often solve such problems by identifying the logical pattern. Notice how the dots are added sequentially for 1 and 2, and then patterns emerge. In an exam, look for the simplest possible sequence, which is often numerical or alphabetical.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
The image displays a grid of characters written in the Braille alphabet, which is a tactile writing system used by visually impaired people. The question requires identifying the missing character in a logical sequence.
Step 2: Key Formula or Approach:
The approach is to first recognize the pattern in the grid. This involves decoding the Braille characters. In Braille, numbers 1 through 9 and 0 are represented by the same patterns as the letters 'a' through 'j'.


⠁ represents 1 (and 'a')
⠃ represents 2 (and 'b')
⠉ represents 3 (and 'c')
⠙ represents 4 (and 'd')
⠑ represents 5 (and 'e')
⠋ represents 6 (and 'f')
⠛ represents 7 (and 'g')
⠓ represents 8 (and 'h')
⠊ represents 9 (and 'i')
⠚ represents 0 (and 'j')
Step 3: Detailed Explanation:
Let's decode the grid row by row:


Row 1: ⠁ ⠃ ⠉ ⠙ ⠑ translates to the numbers 1, 2, 3, 4, 5.
Row 2: ⠋ ⠛ ⠓ ⠊ ⠚ translates to the numbers 6, 7, 8, 9, 0.
Row 3: ⠁ ⠃ ⠉ ? ⠑ translates to the numbers 1, 2, 3, ?, 5.
The pattern in the third row is a simple numerical sequence. The missing number is clearly 4.
We now need to find the Braille representation for the number 4. As listed above, the Braille for 4 is ⠙.
Comparing this with the given options:


(A) is ⠙.
(B) is ⠚ (0).
(C) is ⠛ (7).
(D) is ⠋ (6).
Step 4: Final Answer:
The missing character is the Braille for the number 4, which is represented by option (A).
