To determine the sales tax charged, we need to identify the difference between the final price of the TV set and its original cost. The step-by-step calculations are as follows:
1. Identify the original cost of the TV set:
The original cost is Rs. 25,000.
2. Identify the final cost of the TV set:
The final cost is Rs. 32,000.
3. Calculate the sales tax charged:
The sales tax charged is the difference between the final cost and the original cost.
So, we proceed with the calculation:
[tex]\[ \text{Sales Tax} = \text{Final Cost} - \text{Original Cost} \][/tex]
Substituting the given values:
[tex]\[ \text{Sales Tax} = 32,000 \, \text{Rs.} - 25,000 \, \text{Rs.} \][/tex]
[tex]\[ \text{Sales Tax} = 7,000 \, \text{Rs.} \][/tex]
Therefore, the sales tax charged on the TV set is Rs. 7,000.
