A sofa set costs $2400 before GST. What is cost of thr sofa set after GST?

To find the cost of the sofa set after GST, you need to know the GST rate. The GST rate varies from country to country. Let's assume the GST rate is 10%.

To calculate the GST: GST = (GST rate/100) * cost of the sofa set before GST
GST = (10/100) * 2400
GST = 240

Add the GST to the cost of the sofa set before GST to find the total cost after GST:
Total cost after GST = Cost of the sofa set before GST + GST
Total cost after GST = 2400 + 240
Total cost after GST = 2640

Therefore, the cost of the sofa set after GST is $2640.
