Q.A shopkeeper sells an article with a list price of Rs 2,400 and charges sales tax at 6%. Find the sales tax amount and the total price paid by the customer.

Apply the sales tax formula directly to the given list price.

Tax = Rs 2,400 × 6% = Rs 144. Total = Rs 2,400 + Rs 144 = Rs 2,544.

List price P = Rs 2,400, rate r = 6%.

Sales tax = 2,400 × 6/100 = Rs 144.

Total price paid = 2,400 + 144 = Rs 2,544.

Check: 2,400 × 1.06 = 2,544 — matches.

Rounding the tax or the product prematurely can introduce small errors — carry exact values through both the tax calculation and the total-price addition.
