Sure, let's solve this step by step:
1. Identify the original cost and the total amount paid:
- Original cost of the calculator: Rs. 150
- Total amount Sandesh paid: Rs. 175
2. Determine the VAT amount:
- The VAT amount is the difference between the total amount paid and the original cost of the calculator.
- VAT amount = Total amount paid - Original cost
- VAT amount = 175 - 150
- VAT amount = Rs. 25
3. Calculate the VAT percentage:
- The VAT percentage is calculated by dividing the VAT amount by the original cost and then multiplying by 100 to get the percentage.
- VAT percentage = (VAT amount / Original cost) 100
- VAT percentage = (25 / 150) 100
- VAT percentage = 16.666666666666664%
Therefore, the VAT amount is Rs. 25, and the VAT percentage is approximately 16.67%.
