A shirt whose markedprice is 800 shillings is sold to a customer after allowing him a discount of 13 percent if the trader makes a profit of 20 percent find how much the trader paid for the shirt

The selling price of the shirt after the discount can be calculated as:

Selling price = Marked price - Discount
Selling price = 800 - (13/100)*800
Selling price = 800 - 104
Selling price = 696 shillings

Let the cost price of the shirt for the trader be x.

The profit made by the trader is given by:

Profit = Selling price - Cost price
20/100 * x = 696 - x

Solving for x, we get:

x = 870 shillings

Therefore, the trader paid 870 shillings for the shirt.
