# Brinda purchased 18 coats at the rate of Rs 1,500 each and sold them at a profit of 6%. If customer is to pay sales tax at the rate of 4%, how much will one coat cost to the customer and what will be the total profit earned by Brinda after selling all coats?

Given, the cost price of each coat = Rs. 1500

Also the total number of coat purchased = 18

We need to find out the cost of each coat and profit

earned by brinda.

Now, we know that the total cost of 18 coats = total

number of coats * cost of each coat.

Total cost of 18 coats = 18*1500

= 27000

Gain% = 6%

Now, we know that

Gain =

= 1620

Now, we know that Selling price = Gain + Costprice

Amount received by brinda = 1620 + 27000

= 28620

Customer pay sales tax = 4%

Now, we know that the TotalSalesTax = Cost x SalesTax

TotalSalesTax

= 1144.8

Now, The cost price with the sales tax TotalCost = Cost + TotalSalesTax.

Total cost with sales tax = 28620 + 1144.8

= Rs. 29764.8

Cost Price of one coat =

Cost price of one coat =

= Rs.1653.6

Profit earned by Brinda = 28620 – 27000

= 1620

Hence, Brinda earned the profit of 1620
