Which sign is wrong in notation system :

Question

Accepted Answer

Option 3 is identified as the correct answer because it highlights a discrepancy in the notation system between the Bhatkhande and Paluskar methods for representing the note "Komal." In the Bhatkhande system, "Komal" notes are typically denoted with an underline (e.g., Re̲), whereas in the Paluskar system, "Komal" notes are often indicated with a small line or a different symbol, but not typically with a superscript "l" as shown in Reˡ. This inconsistency in notation is why Option 3 is considered incorrect.

Now, let's examine why the other options are not considered incorrect:

1. **Option 1: Sam**
   - In the Bhatkhande system, "Sam" is often denoted by the symbol "x," and in the Paluskar system, it is represented by "l." Both notations are standard and accepted within their respective systems, so there is no discrepancy here.

2. **Option 2: Khali**
   - The Bhatkhande system uses "0" to denote "Khali," and the Paluskar system uses "+." These symbols are widely recognized and accepted in their respective systems for indicating "Khali," so there is no error in this notation.

3. **Option 4: Mandra**
   - In the Bhatkhande system, "Mandra" notes are indicated by their respective note names, such as "Dha," and in the Paluskar system, they are often marked with a circumflex accent, like "Dhâ," to denote the lower octave. This is a standard practice, and there is no inconsistency here.

In conclusion, Option 3 is the correct answer because it presents a notation inconsistency between the Bhatkhande and Paluskar systems for "Komal" notes, which is not present in the other options.
