Final answer:
The VAT percent is found by dividing the VAT amount (45, the difference between SP with VAT and original SP) by the original SP (450) and multiplying by 100, resulting in a VAT percent of 10%.
Step-by-step explanation:
To find the VAT percent, we need to calculate the percentage increase from the original selling price (SP) to the selling price including VAT.
The original SP is 450, and the SP with VAT is 495. The increase due to VAT is calculated by subtracting the original SP from the SP with VAT:
VAT amount = SP with VAT - original SP
VAT amount = 495 - 450
VAT amount = 45
To find the VAT percent, we divide the VAT amount by the original SP and multiply by 100:
VAT percent = (VAT amount / original SP) × 100
VAT percent = (45 / 450) × 100
VAT percent = 0.1 × 100
VAT percent = 10%
Therefore, the VAT percent is 10%.
