Step-by-step explanation:

Cost price of item 1 = C1

Profit = (10/100)*C1 = 0.1C1

Selling Price = C1 + 0.1C1 = 1.1C1

1.1C1 = 2000

C1 =  1818.18

Cost price of item 2 = C2

Loss = (10/100)*C2 = 0.1C2

Selling Price = C2 - ).1C2 = 0.9C2

0.9C2 = 2000

C2 = 2222.22

C1 + C2 = 1818.18 + 2222.22 = 4040.4

Selling price = 2000 + 2000 = 4000

Loss = 4040.4 - 4000 = 40.4

Loss % = (40.4/4040.4)*100 = 0.9999 % almost equal to 1%
