Deepa purchased 15 shirts at the rate of Rs. 1,200 each and sold them at a profit of 5%. If the customer has to pay sales tax at the rate of 4%, how much will one shirt cost to the customer?

Cost of each shirt = 1,200

No. of shirts = 15

Cost price of shirts = 15 × 1,200 = 18,000

Profit = 5%

= × 18,000

= 900

Total cost price = 18,000 + 900 = 18,900

Sales Tax = 4%

Amount of sales tax = (Rate of sales tax) (cost price)

= × 18,900

= 756

Total cost that customer has to pay = cost price + sales tax amount

= 18,900 + 756

= 19,656

Cost of 15 shirt that customer pay = 19,656

Cost of 1 shirt that customer has to pay = = 1,310.40
